The Portfolio's Management Fee structure is a “bifurcated fee” structure as follows: an annual rate of 0.20% of the Portfolio's average daily net assets invested in Underlying Funds within the Voya family of funds, and 0.40% of the Portfolio's average daily net assets invested in direct investments.
2
Total Annual Portfolio Operating Expenses may be higher than the Portfolio's ratio of expenses to average net assets shown in the Portfolio's Financial Highlights, which reflects the operating expenses of the Portfolio and does not include Acquired Fund Fees and Expenses.

The adviser is contractually obligated to limit expenses to 0.89%, 0.39%, 0.64%, and 0.79% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses, and extraordinary expenses. Termination or modification of this obligation requires approval by the Portfolio’s board.
Expense Example
The 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 30% of the average value of its portfolio.

Voya Index Solution Income Portfolio

Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in a combination of Underlying Funds, which are passively managed index funds. The Portfolio will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Portfolio uses an asset allocation strategy designed for investors expecting to retire soon or are already retired. The Portfolio's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is as follows: 35% in equity securities and 65% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown. In establishing the Portfolio’s exposure to debt instruments, the investment adviser will set target allocations to funding agreements with affiliated or unaffiliated (if available) insurance companies (collectively, “Funding Agreements”), which will not exceed 10% in the case of contracts of any single issuer or 20% for all issuers combined. Because those are target allocations, the Portfolio’ s actual allocations might exceed those percentages at times due to a variety of factors, such as changes in the relative values of the Portfolio’s investments and cash flows into and out of the Portfolio, and at those times the Portfolio will typically continue to invest new cash in accordance with those target allocations.
At least 80% of the Portfolio’s assets will normally be invested in Underlying Funds affiliated with the investment adviser; this amount may include investments in one or more Funding Agreements issued by Voya Retirement Insurance and Annuity Company (“VRIAC”). The sub-adviser (“Sub-Adviser”) may in its discretion invest up to 20% of the Portfolio’s assets in Underlying Funds, including exchange-traded funds, that are not affiliated with the investment adviser and, potentially, in Funding Agreements issued by insurance companies unaffiliated with the investment adviser, should they be available for investment by the Portfolio.
The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to debt instruments and equity securities will vary from the Target Allocation depending on the actual investments held by the Underlying Funds. The Sub-Adviser may periodically cause the Portfolio to deviate from the Target Allocation based on its assessment of current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Portfolio, achieve its investment objective, or to take advantage of particular opportunities.
The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds and cash.
Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented or a blend); and emerging market securities.
Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international intermediate-, long-, and short-term bonds; high-yield bonds commonly referred to as “junk-bonds”; floating rate loans; and Funding Agreements.
The Portfolio may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, to minimize risk, and to assist in managing cash.
The Portfolio may also allocate to the following non-traditional asset classes (also known as alternative strategies) which include but are not limited to: domestic and international real estate-related securities, including real estate investment trusts; natural resource/commodity securities; and treasury inflation protected securities. There can be no assurance that these allocations will occur.
The Portfolio will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Principal Risks
You could lose money on an investment in the Portfolio. There is no guarantee that the Portfolio will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Portfolio changes with the values of the Underlying Funds and their investments. The Portfolio is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Portfolio's or an Underlying Fund's performance or cause the Portfolio or an Underlying Fund to lose money or to underperform market averages of other funds.
Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue to the manager and its affiliates, even if that results in increased expenses for the Portfolio. In many cases, investments in affiliated Underlying Funds will afford the manager greater net management fee revenue than would investments in unaffiliated Underlying Funds. In addition, the manager may prefer to invest in an
Voya Index Solution Income Portfolio
2

affiliated Underlying Fund over an unaffiliated fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund, by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Portfolio may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees than the comparable affiliated Underlying Funds. If the Portfolio invests in an Underlying Fund with higher expenses, the Portfolio’s performance would be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).
Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Portfolio invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to an asset class that underperforms compared to other asset classes or investments.
Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Portfolio’s performance and ability to achieve its investment objective.
Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.
Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether.
Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Portfolio will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks and the risk that the swap may not correlate with its underlying asset as expected. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that central clearing will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to new kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
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.
Deflation: Deflation occurs when prices throughout the economy decline over time - the opposite of inflation. When there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the 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 currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.
Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Portfolio will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. If a floating rate loan is held by the Portfolio through another financial institution, or the Portfolio relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the
Voya Index Solution Income Portfolio
3

credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer’s obligations under the loan. Furthermore, such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Portfolio may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Portfolio to meet its redemption obligations. It may also limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.
Foreign 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 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; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.
Funding Agreements: A Portfolio may invest in Funding Agreements issued by insurance companies affiliated with the investment adviser and Sub-Adviser, such as VRIAC, and insurance companies unaffiliated with the investment adviser and Sub-Adviser. A Funding Agreement has a stable principal value and typically pays interest at a relatively short-term rate, which is subject to change periodically. Investment in a Funding Agreement is subject to the credit risk of the insurer, and an insurer may be unable to repay the entire amount of principal and interest due under a Funding Agreement. In a rising interest rate environment, the interest rate provided by a Funding Agreement may not increase as quickly as the yields of other short-term investments, adversely affecting a Portfolio’s performance. In the case of a Funding Agreement with VRIAC, there can be no guarantee that the interest rate a Portfolio receives under such a Funding Agreement will be as favorable to a Portfolio as the rate that might be paid under a Funding Agreement with another, unaffiliated insurer.
The Sub-Adviser’s decision to invest in a Funding Agreement issued by VRIAC presents conflicts of interest. VRIAC will typically invest the proceeds of the Funding Agreement at a spread above what it agrees to pay a Portfolio, resulting in a financial benefit to VRIAC, and the Sub-Adviser receives a management fee from VRIAC for managing the proceeds of the Funding Agreement (along with the proceeds of other funding agreements issued by VRIAC). In addition, an investment in a Funding Agreement may have the effect of reducing a Portfolio’s gross expenses, thereby also reducing the investment adviser’s obligations under fee waiver and expense limitation arrangements with a Portfolio. Any changes in the interest rate paid by VRIAC on a Funding Agreement is determined by VRIAC, with prior notice to a Portfolio. The Sub-Adviser may have a financial incentive to invest a greater percentage of a Portfolio’s assets in a Funding Agreement with VRIAC than the percentage of a Portfolio’s assets it might invest in obligations of any other single issuer, including following a reduction in the interest rate paid on the Funding Agreement. A Portfolio’s affiliation with VRIAC might delay or limit a Portfolio’s ability to recover its investment in a Funding Agreement in the event of an insolvency of VRIAC. The Sub-Adviser is subject to a fiduciary duty to a Portfolio in its decisions as to whether, and how much, a Portfolio should invest in a Funding Agreement with VRIAC at any time. In addition, investments by a Portfolio in a Funding Agreement with VRIAC must comply with conditions set forth in applicable exemptive relief provided by the Securities and Exchange Commission designed to mitigate the foregoing conflicts of interest, and in related policies and procedures adopted by a Portfolio’s Board of Directors.
Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.
High-Yield Securities: Lower quality securities (including securities that have fallen below investment-grade and are classified as “junk bonds” or “high yield securities”) have greater credit risk and liquidity risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.
Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by
Voya Index Solution Income Portfolio
4

the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. In particular, when deciding between Underlying Index Funds benchmarked to the same index, the manager will generally select an affiliated Underlying Index Fund, even when the affiliated Underlying Index Fund has higher expenses than an unaffiliated Underlying Index Fund. When the Portfolio invests in an affiliated Underlying Index Fund with higher expenses, the Portfolio’s performance will be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance). The manager may select an unaffiliated Underlying Index Fund, including an exchange-traded fund, over an affiliated Underlying Fund benchmarked to the same index when the manager believes making an investment in the affiliated Underlying Index Fund would be disadvantageous to the affiliated Underlying Index Fund, such as when the Portfolio is investing on a short term basis.
Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.
Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the 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 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.
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.
The Chinese economy is generally considered an emerging and volatile market. 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. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States of America 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 Adviser otherwise believes is attractive, the Portfolio may incur losses.

LIBOR: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based in whole or in part on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including among others a Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. Discontinuance of LIBOR and adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Portfolio’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of an the Portfolio; and the risk of general market disruption during the transition period. Markets relying on new, non-LIBOR rates are developing slowly, and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to other rates could have a substantial adverse impact on the performance of an the Portfolio.
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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.
Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger 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 U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, 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 could adversely affect global energy and financial markets and therefore could affect the value of a Portfolio’s investments, including beyond a 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. Those events as well as other changes in 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 investments of the Portfolio and the Portfolio. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.

Natural Resources/Commodity Securities: The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.
Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Portfolio. 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.
Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This may occur when interest rates decline. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a debt 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 debt instrument will pay back the principal later than expected. This may occur when interest rates rise. This may negatively affect performance, as the value of the debt 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.
Real Estate Companies and Real Estate Investment Trusts (“REITs”): 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, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.
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. A particular risk of the Portfolio’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly.
An investment in the 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 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 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
Until the day prior to its Target Date (defined below), the Portfolio seeks to provide total return consistent with an asset allocation targeted at retirement in approximately 2025. On the Target Date, the Portfolio's investment objective will be to seek to provide a combination of total return and stability of principal consistent with an asset allocation targeted to retirement.
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.

The adviser is contractually obligated to limit expenses to 0.89%, 0.39%, 0.64%, and 0.79% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses and extraordinary expenses. Termination or modification of this obligation requires approval by the Portfolio’s board.
Expense Example
The 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 40% of the average value of its portfolio.

Voya Index Solution 2025 Portfolio

Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in a combination of Underlying Funds which are passively managed index funds. The Portfolio will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Portfolio uses an asset allocation strategy designed for investors expecting to retire around the year 2025. The Portfolio's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is as follows: 45% in equity securities and 55% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown. In establishing the Portfolio’s exposure to debt instruments, the investment adviser will set target allocations to funding agreements with affiliated or unaffiliated (if available) insurance companies (collectively, “Funding Agreements”), which will not exceed 10% in the case of contracts of any single issuer or 20% for all issuers combined. Because those are target allocations, the Portfolio’ s actual allocations might exceed those percentages at times due to a variety of factors, such as changes in the relative values of the Portfolio’s investments and cash flows into and out of the Portfolio, and at those times the Portfolio will typically continue to invest new cash in accordance with those target allocations.
At least 80% of the Portfolio’s assets will normally be invested in Underlying Funds affiliated with the investment adviser; this amount may include investments in one or more Funding Agreements issued by Voya Retirement Insurance and Annuity Company (“VRIAC”). The sub-adviser (“Sub-Adviser”) may in its discretion invest up to 20% of the Portfolio’s assets in Underlying Funds, including exchange-traded funds, that are not affiliated with the investment adviser and, potentially, in Funding Agreements issued by insurance companies unaffiliated with the investment adviser, should they be available for investment by the Portfolio.
The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to debt instruments and equity securities will vary from the Target Allocation depending on the actual investments held by the Underlying Funds. The Sub-Adviser may periodically cause the Portfolio to deviate from the Target Allocation based on its assessment of current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Portfolio, achieve its investment objective, or to take advantage of particular opportunities.
The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds and cash.
Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented or a blend); and emerging market securities.
Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international intermediate-, long-, and short-term bonds; high-yield bonds commonly referred to as “junk-bonds”; floating rate loans; and Funding Agreements.
The Portfolio may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, to minimize risk, and to assist in managing cash.
The Portfolio may also allocate to the following non-traditional asset classes (also known as alternative strategies) which include but are not limited to: domestic and international real estate-related securities, including real estate investment trusts; natural resource/commodity securities; and treasury inflation protected securities. There can be no assurance that these allocations will occur.
The Portfolio is designed primarily for long-term investors in tax-advantaged accounts. The Portfolio is structured and managed around a specific target retirement or financial goal date of 2025 (“Target Date”). The Target Date is the approximate year that an investor in the Portfolio would plan to make withdrawals from the Portfolio for retirement or other financial goals. The chart below shows the glide path and illustrates how the target allocations to equity securities and debt instruments will change over time. Generally, the Portfolio's glide path will transition to the target asset allocation illustrated below on an annual basis and become more conservative as the Portfolio approaches the Target Date. As the Portfolio approaches its Target Date, the Portfolio's Target Allocation is anticipated to be the same as that of Voya Index Solution Income Portfolio, which is equal to approximately 35% equity securities and 65% debt instruments.
Voya Index Solution 2025 Portfolio
11

As the Portfolio's Target Allocation migrates toward that of Voya Index Solution Income Portfolio by the Target Date, it is anticipated that the Portfolio would be merged with and into the Voya Index Solution Income Portfolio. The Voya Index Solution Income Portfolio is for those investors who are retired, nearing retirement or in need of making withdrawals from their portfolio soon.
In summary, the Portfolio is designed for an investor who plans to withdraw the value of the investor's investments in the Portfolio gradually on or after the Target Date. The mix of investments in the Portfolio's Target Allocation will change over time and seek to reduce investment risk as the Portfolio approaches its Target Date.
The Portfolio will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Principal Risks
You could lose money on an investment in the Portfolio, even near, at, or after the Target Date. There is no guarantee that the Portfolio will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Portfolio changes with the values of the Underlying Funds and their investments. The Portfolio is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Portfolio's or an Underlying Fund's performance or cause the Portfolio or an Underlying Fund to lose money or to underperform market averages of other funds.
Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue to the manager and its affiliates, even if that results in increased expenses for the Portfolio. In many cases, investments in affiliated Underlying Funds will afford the manager greater net management fee revenue than would investments in unaffiliated Underlying Funds. In addition, the manager may prefer to invest in an affiliated Underlying Fund over an unaffiliated fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund, by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Portfolio may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees than the comparable affiliated Underlying Funds. If the Portfolio invests in an Underlying Fund with higher expenses, the Portfolio’s performance would be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).
Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Portfolio invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to an asset class that underperforms compared to other asset classes or investments.
Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Portfolio’s performance and ability to achieve its investment objective.
Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.
Voya Index Solution 2025 Portfolio
12

Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether.
Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Portfolio will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks and the risk that the swap may not correlate with its underlying asset as expected. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that central clearing will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to new kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
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.
Deflation: Deflation occurs when prices throughout the economy decline over time - the opposite of inflation. When there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the 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 currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.
Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Portfolio will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. If a floating rate loan is held by the Portfolio through another financial institution, or the Portfolio relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer’s obligations under the loan. Furthermore, such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Portfolio may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Portfolio to meet its redemption obligations. It may also limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.
Foreign 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 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; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.
Voya Index Solution 2025 Portfolio
13

Funding Agreements: A Portfolio may invest in Funding Agreements issued by insurance companies affiliated with the investment adviser and Sub-Adviser, such as VRIAC, and insurance companies unaffiliated with the investment adviser and Sub-Adviser. A Funding Agreement has a stable principal value and typically pays interest at a relatively short-term rate, which is subject to change periodically. Investment in a Funding Agreement is subject to the credit risk of the insurer, and an insurer may be unable to repay the entire amount of principal and interest due under a Funding Agreement. In a rising interest rate environment, the interest rate provided by a Funding Agreement may not increase as quickly as the yields of other short-term investments, adversely affecting a Portfolio’s performance. In the case of a Funding Agreement with VRIAC, there can be no guarantee that the interest rate a Portfolio receives under such a Funding Agreement will be as favorable to a Portfolio as the rate that might be paid under a Funding Agreement with another, unaffiliated insurer.
The Sub-Adviser’s decision to invest in a Funding Agreement issued by VRIAC presents conflicts of interest. VRIAC will typically invest the proceeds of the Funding Agreement at a spread above what it agrees to pay a Portfolio, resulting in a financial benefit to VRIAC, and the Sub-Adviser receives a management fee from VRIAC for managing the proceeds of the Funding Agreement (along with the proceeds of other funding agreements issued by VRIAC). In addition, an investment in a Funding Agreement may have the effect of reducing a Portfolio’s gross expenses, thereby also reducing the investment adviser’s obligations under fee waiver and expense limitation arrangements with a Portfolio. Any changes in the interest rate paid by VRIAC on a Funding Agreement is determined by VRIAC, with prior notice to a Portfolio. The Sub-Adviser may have a financial incentive to invest a greater percentage of a Portfolio’s assets in a Funding Agreement with VRIAC than the percentage of a Portfolio’s assets it might invest in obligations of any other single issuer, including following a reduction in the interest rate paid on the Funding Agreement. A Portfolio’s affiliation with VRIAC might delay or limit a Portfolio’s ability to recover its investment in a Funding Agreement in the event of an insolvency of VRIAC. The Sub-Adviser is subject to a fiduciary duty to a Portfolio in its decisions as to whether, and how much, a Portfolio should invest in a Funding Agreement with VRIAC at any time. In addition, investments by a Portfolio in a Funding Agreement with VRIAC must comply with conditions set forth in applicable exemptive relief provided by the Securities and Exchange Commission designed to mitigate the foregoing conflicts of interest, and in related policies and procedures adopted by a Portfolio’s Board of Directors.
Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.
High-Yield Securities: Lower quality securities (including securities that have fallen below investment-grade and are classified as “junk bonds” or “high yield securities”) have greater credit risk and liquidity risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.
Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. In particular, when deciding between Underlying Index Funds benchmarked to the same index, the manager will generally select an affiliated Underlying Index Fund, even when the affiliated Underlying Index Fund has higher expenses than an unaffiliated Underlying Index Fund. When the Portfolio invests in an affiliated Underlying Index Fund with higher expenses, the Portfolio’s performance will be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance). The manager may select an unaffiliated Underlying Index Fund, including an exchange-traded fund, over an affiliated Underlying Fund benchmarked to the same index when the manager believes making an investment in the affiliated Underlying Index Fund would be disadvantageous to the affiliated Underlying Index Fund, such as when the Portfolio is investing on a short term basis.
Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as
Voya Index Solution 2025 Portfolio

interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.
Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the 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 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.
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.
The Chinese economy is generally considered an emerging and volatile market. 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. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States of America 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 Adviser otherwise believes is attractive, the Portfolio may incur losses.
LIBOR: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based in whole or in part on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including among others a Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. Discontinuance of LIBOR and adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Portfolio’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of an the Portfolio; and the risk of general market disruption during the transition period. Markets relying on new, non-LIBOR rates are developing slowly, and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to other rates could have a substantial adverse impact on the performance of an the Portfolio.

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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.
Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger 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 U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, 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 could adversely affect global energy and financial markets and therefore could affect the value of a Portfolio’s investments, including beyond a 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. Those events as well as other changes in 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 investments of the Portfolio and the Portfolio. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.
Natural Resources/Commodity Securities: The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.
Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Portfolio. 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.
Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This may occur when interest rates decline. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a debt 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 debt instrument will pay back the principal later than expected.
Voya Index Solution 2025 Portfolio

This may occur when interest rates rise. This may negatively affect performance, as the value of the debt 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.
Real Estate Companies and Real Estate Investment Trusts (“REITs”): 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, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.
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. A particular risk of the Portfolio’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly.
An investment in the 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 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 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
Until the day prior to its Target Date (defined below), the Portfolio seeks to provide total return consistent with an asset allocation targeted at retirement in approximately 2030. On the Target Date, the Portfolio's investment objective will be to seek to provide a combination of total return and stability of principal consistent with an asset allocation targeted to retirement.
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.

The adviser is contractually obligated to limit expenses to 0.89%, 0.39%, 0.64%, and 0.79% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses and extraordinary expenses. Termination or modification of this obligation requires approval by the Portfolio’s board.
Expense Example
The 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 41% of the average value of its portfolio.

Voya Index Solution 2030 Portfolio

Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in a combination of Underlying Funds which are passively managed index funds. The Portfolio will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Portfolio uses an asset allocation strategy designed for investors expecting to retire around the year 2030. The Portfolio's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is as follows: 57% in equity securities and 43% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown. In establishing the Portfolio’s exposure to debt instruments, the investment adviser will set target allocations to funding agreements with affiliated or unaffiliated (if available) insurance companies (collectively, “Funding Agreements”), which will not exceed 10% in the case of contracts of any single issuer or 20% for all issuers combined. Because those are target allocations, the Portfolio’ s actual allocations might exceed those percentages at times due to a variety of factors, such as changes in the relative values of the Portfolio’s investments and cash flows into and out of the Portfolio, and at those times the Portfolio will typically continue to invest new cash in accordance with those target allocations.
At least 80% of the Portfolio’s assets will normally be invested in Underlying Funds affiliated with the investment adviser; this amount may include investments in one or more Funding Agreements issued by Voya Retirement Insurance and Annuity Company (“VRIAC”). The sub-adviser (“Sub-Adviser”) may in its discretion invest up to 20% of the Portfolio’s assets in Underlying Funds, including exchange-traded funds, that are not affiliated with the investment adviser and, potentially, in Funding Agreements issued by insurance companies unaffiliated with the investment adviser, should they be available for investment by the Portfolio.
The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to debt instruments and equity securities will vary from the Target Allocation depending on the actual investments held by the Underlying Funds. The Sub-Adviser may periodically cause the Portfolio to deviate from the Target Allocation based on its assessment of current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Portfolio, achieve its investment objective, or to take advantage of particular opportunities.
The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds and cash.
Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented or a blend); and emerging market securities.
Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international intermediate-, long-, and short-term bonds; high-yield bonds commonly referred to as “junk-bonds”; floating rate loans; and Funding Agreements.
The Portfolio may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, to minimize risk, and to assist in managing cash.
The Portfolio may also allocate to the following non-traditional asset classes (also known as alternative strategies) which include but are not limited to: domestic and international real estate-related securities, including real estate investment trusts; natural resource/commodity securities; and treasury inflation protected securities. There can be no assurance that these allocations will occur.
The Portfolio is designed primarily for long-term investors in tax-advantaged accounts. The Portfolio is structured and managed around a specific target retirement or financial goal date of 2030 (“Target Date”). The Target Date is the approximate year that an investor in the Portfolio would plan to make withdrawals from the Portfolio for retirement or other financial goals. The chart below shows the glide path and illustrates how the target allocations to equity securities and debt instruments will change over time. Generally, the Portfolio's glide path will transition to the target asset allocation illustrated below on an annual basis and become more conservative as the Portfolio approaches the Target Date. As the Portfolio approaches its Target Date, the Portfolio's Target Allocation is anticipated to be the same as that of Voya Index Solution Income Portfolio, which is equal to approximately 35% equity securities and 65% debt instruments.
Voya Index Solution 2030 Portfolio
21

As the Portfolio's Target Allocation migrates toward that of Voya Index Solution Income Portfolio by the Target Date, it is anticipated that the Portfolio would be merged with and into the Voya Index Solution Income Portfolio. The Voya Index Solution Income Portfolio is for those investors who are retired, nearing retirement or in need of making withdrawals from their portfolio soon.
In summary, the Portfolio is designed for an investor who plans to withdraw the value of the investor's investments in the Portfolio gradually on or after the Target Date. The mix of investments in the Portfolio's Target Allocation will change over time and seek to reduce investment risk as the Portfolio approaches its Target Date.
The Portfolio will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Principal Risks
You could lose money on an investment in the Portfolio, even near, at, or after the Target Date. There is no guarantee that the Portfolio will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Portfolio changes with the values of the Underlying Funds and their investments. The Portfolio is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Portfolio's or an Underlying Fund's performance or cause the Portfolio or an Underlying Fund to lose money or to underperform market averages of other funds.
Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue to the manager and its affiliates, even if that results in increased expenses for the Portfolio. In many cases, investments in affiliated Underlying Funds will afford the manager greater net management fee revenue than would investments in unaffiliated Underlying Funds. In addition, the manager may prefer to invest in an affiliated Underlying Fund over an unaffiliated fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund, by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Portfolio may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees than the comparable affiliated Underlying Funds. If the Portfolio invests in an Underlying Fund with higher expenses, the Portfolio’s performance would be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).
Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Portfolio invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to an asset class that underperforms compared to other asset classes or investments.
Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Portfolio’s performance and ability to achieve its investment objective.
Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.
Voya Index Solution 2030 Portfolio
22

Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether.
Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Portfolio will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks and the risk that the swap may not correlate with its underlying asset as expected. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that central clearing will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to new kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
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.
Deflation: Deflation occurs when prices throughout the economy decline over time - the opposite of inflation. When there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the 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 currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.
Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Portfolio will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. If a floating rate loan is held by the Portfolio through another financial institution, or the Portfolio relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer’s obligations under the loan. Furthermore, such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Portfolio may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Portfolio to meet its redemption obligations. It may also limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.
Foreign 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 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; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.

Funding Agreements: A Portfolio may invest in Funding Agreements issued by insurance companies affiliated with the investment adviser and Sub-Adviser, such as VRIAC, and insurance companies unaffiliated with the investment adviser and Sub-Adviser. A Funding Agreement has a stable principal value and typically pays interest at a relatively short-term rate, which is subject to change periodically. Investment in a Funding Agreement is subject to the credit risk of the insurer, and an insurer may be unable to repay the entire amount of principal and interest due under a Funding Agreement. In a rising interest rate environment, the interest rate provided by a Funding Agreement may not increase as quickly as the yields of other short-term investments, adversely affecting a Portfolio’s performance. In the case of a Funding Agreement with VRIAC, there can be no guarantee that the interest rate a Portfolio receives under such a Funding Agreement will be as favorable to a Portfolio as the rate that might be paid under a Funding Agreement with another, unaffiliated insurer.
The Sub-Adviser’s decision to invest in a Funding Agreement issued by VRIAC presents conflicts of interest. VRIAC will typically invest the proceeds of the Funding Agreement at a spread above what it agrees to pay a Portfolio, resulting in a financial benefit to VRIAC, and the Sub-Adviser receives a management fee from VRIAC for managing the proceeds of the Funding Agreement (along with the proceeds of other funding agreements issued by VRIAC). In addition, an investment in a Funding Agreement may have the effect of reducing a Portfolio’s gross expenses, thereby also reducing the investment adviser’s obligations under fee waiver and expense limitation arrangements with a Portfolio. Any changes in the interest rate paid by VRIAC on a Funding Agreement is determined by VRIAC, with prior notice to a Portfolio. The Sub-Adviser may have a financial incentive to invest a greater percentage of a Portfolio’s assets in a Funding Agreement with VRIAC than the percentage of a Portfolio’s assets it might invest in obligations of any other single issuer, including following a reduction in the interest rate paid on the Funding Agreement. A Portfolio’s affiliation with VRIAC might delay or limit a Portfolio’s ability to recover its investment in a Funding Agreement in the event of an insolvency of VRIAC. The Sub-Adviser is subject to a fiduciary duty to a Portfolio in its decisions as to whether, and how much, a Portfolio should invest in a Funding Agreement with VRIAC at any time. In addition, investments by a Portfolio in a Funding Agreement with VRIAC must comply with conditions set forth in applicable exemptive relief provided by the Securities and Exchange Commission designed to mitigate the foregoing conflicts of interest, and in related policies and procedures adopted by a Portfolio’s Board of Directors.
Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.
High-Yield Securities: Lower quality securities (including securities that have fallen below investment-grade and are classified as “junk bonds” or “high yield securities”) have greater credit risk and liquidity risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.
Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. In particular, when deciding between Underlying Index Funds benchmarked to the same index, the manager will generally select an affiliated Underlying Index Fund, even when the affiliated Underlying Index Fund has higher expenses than an unaffiliated Underlying Index Fund. When the Portfolio invests in an affiliated Underlying Index Fund with higher expenses, the Portfolio’s performance will be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance). The manager may select an unaffiliated Underlying Index Fund, including an exchange-traded fund, over an affiliated Underlying Fund benchmarked to the same index when the manager believes making an investment in the affiliated Underlying Index Fund would be disadvantageous to the affiliated Underlying Index Fund, such as when the Portfolio is investing on a short term basis.
Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as
Voya Index Solution 2030 Portfolio
24

interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.
Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the 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 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.
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.
The Chinese economy is generally considered an emerging and volatile market. 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. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States of America 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 Adviser otherwise believes is attractive, the Portfolio may incur losses.
LIBOR: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based in whole or in part on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including among others a Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. Discontinuance of LIBOR and adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Portfolio’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of an the Portfolio; and the risk of general market disruption during the transition period. Markets relying on new, non-LIBOR rates are developing slowly, and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to other rates could have a substantial adverse impact on the performance of an the Portfolio.
Voya Index Solution 2030 Portfolio

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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.
Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger 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 U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, 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 could adversely affect global energy and financial markets and therefore could affect the value of a Portfolio’s investments, including beyond a 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. Those events as well as other changes in 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 investments of the Portfolio and the Portfolio. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.
Natural Resources/Commodity Securities: The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.
Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Portfolio. 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.
Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This may occur when interest rates decline. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a debt 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 debt instrument will pay back the principal later than expected.
Voya Index Solution 2030 Portfolio
26

This may occur when interest rates rise. This may negatively affect performance, as the value of the debt 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.
Real Estate Companies and Real Estate Investment Trusts (“REITs”): 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, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.
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. A particular risk of the Portfolio’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly.
An investment in the 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 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 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.

The adviser is contractually obligated to limit expenses to 0.89%, 0.39%, 0.64%, and 0.79% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses and extraordinary expenses. Termination or modification of this obligation requires approval by the Portfolio’s board.
Expense Example
The 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 Index Solution 2035 Portfolio

Principal Investment Strategies
Under normal market conditions, the Portfolio invests at least 80% of its net assets (plus borrowings for investment purposes) in a combination of Underlying Funds which are passively managed index funds. The Portfolio will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Portfolio uses an asset allocation strategy designed for investors expecting to retire around the year 2035. The Portfolio's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is as follows: 68% in equity securities and 32% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown. In establishing the Portfolio’s exposure to debt instruments, the investment adviser will set target allocations to funding agreements with affiliated or unaffiliated (if available) insurance companies (collectively, “Funding Agreements”), which will not exceed 10% in the case of contracts of any single issuer or 20% for all issuers combined. Because those are target allocations, the Portfolio’ s actual allocations might exceed those percentages at times due to a variety of factors, such as changes in the relative values of the Portfolio’s investments and cash flows into and out of the Portfolio, and at those times the Portfolio will typically continue to invest new cash in accordance with those target allocations.
At least 80% of the Portfolio’s assets will normally be invested in Underlying Funds affiliated with the investment adviser; this amount may include investments in one or more Funding Agreements issued by Voya Retirement Insurance and Annuity Company (“VRIAC”). The sub-adviser (“Sub-Adviser”) may in its discretion invest up to 20% of the Portfolio’s assets in Underlying Funds, including exchange-traded funds, that are not affiliated with the investment adviser and, potentially, in Funding Agreements issued by insurance companies unaffiliated with the investment adviser, should they be available for investment by the Portfolio.
The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to debt instruments and equity securities will vary from the Target Allocation depending on the actual investments held by the Underlying Funds. The Sub-Adviser may periodically cause the Portfolio to deviate from the Target Allocation based on its assessment of current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Portfolio, achieve its investment objective, or to take advantage of particular opportunities.
The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds and cash.
Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented or a blend); and emerging market securities.
Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international intermediate-, long-, and short-term bonds; high-yield bonds commonly referred to as “junk-bonds”; floating rate loans; and Funding Agreements.
The Portfolio may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, to minimize risk, and to assist in managing cash.
The Portfolio may also allocate to the following non-traditional asset classes (also known as alternative strategies) which include but are not limited to: domestic and international real estate-related securities, including real estate investment trusts; natural resource/commodity securities; and treasury inflation protected securities. There can be no assurance that these allocations will occur.
The Portfolio is designed primarily for long-term investors in tax-advantaged accounts. The Portfolio is structured and managed around a specific target retirement or financial goal date of 2035 (“Target Date”). The Target Date is the approximate year that an investor in the Portfolio would plan to make withdrawals from the Portfolio for retirement or other financial goals. The chart below shows the glide path and illustrates how the target allocations to equity securities and debt instruments will change over time. Generally, the Portfolio's glide path will transition to the target asset allocation illustrated below on an annual basis and become more conservative as the Portfolio approaches the Target Date. As the Portfolio approaches its Target Date, the Portfolio's Target Allocation is anticipated to be the same as that of Voya Index Solution Income Portfolio, which is equal to approximately 35% equity securities and 65% debt instruments.
Voya Index Solution 2035 Portfolio
30

As the Portfolio's Target Allocation migrates toward that of Voya Index Solution Income Portfolio by the Target Date, it is anticipated that the Portfolio would be merged with and into the Voya Index Solution Income Portfolio. The Voya Index Solution Income Portfolio is for those investors who are retired, nearing retirement or in need of making withdrawals from their portfolio soon.
In summary, the Portfolio is designed for an investor who plans to withdraw the value of the investor's investments in the Portfolio gradually on or after the Target Date. The mix of investments in the Portfolio's Target Allocation will change over time and seek to reduce investment risk as the Portfolio approaches its Target Date.
The Portfolio will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Principal Risks
You could lose money on an investment in the Portfolio, even near, at, or after the Target Date. There is no guarantee that the Portfolio will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Portfolio changes with the values of the Underlying Funds and their investments. The Portfolio is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Portfolio's or an Underlying Fund's performance or cause the Portfolio or an Underlying Fund to lose money or to underperform market averages of other funds.
Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue to the manager and its affiliates, even if that results in increased expenses for the Portfolio. In many cases, investments in affiliated Underlying Funds will afford the manager greater net management fee revenue than would investments in unaffiliated Underlying Funds. In addition, the manager may prefer to invest in an affiliated Underlying Fund over an unaffiliated fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund, by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Portfolio may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees than the comparable affiliated Underlying Funds. If the Portfolio invests in an Underlying Fund with higher expenses, the Portfolio’s performance would be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).
Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Portfolio invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to an asset class that underperforms compared to other asset classes or investments.
Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Portfolio’s performance and ability to achieve its investment objective.
Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.

Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether.
Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Portfolio will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks and the risk that the swap may not correlate with its underlying asset as expected. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that central clearing will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to new kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
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.
Deflation: Deflation occurs when prices throughout the economy decline over time - the opposite of inflation. When there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the 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 currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.
Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Portfolio will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. If a floating rate loan is held by the Portfolio through another financial institution, or the Portfolio relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer’s obligations under the loan. Furthermore, such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Portfolio may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Portfolio to meet its redemption obligations. It may also limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.
Foreign 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 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; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.
Voya Index Solution 2035 Portfolio
32

Funding Agreements: A Portfolio may invest in Funding Agreements issued by insurance companies affiliated with the investment adviser and Sub-Adviser, such as VRIAC, and insurance companies unaffiliated with the investment adviser and Sub-Adviser. A Funding Agreement has a stable principal value and typically pays interest at a relatively short-term rate, which is subject to change periodically. Investment in a Funding Agreement is subject to the credit risk of the insurer, and an insurer may be unable to repay the entire amount of principal and interest due under a Funding Agreement. In a rising interest rate environment, the interest rate provided by a Funding Agreement may not increase as quickly as the yields of other short-term investments, adversely affecting a Portfolio’s performance. In the case of a Funding Agreement with VRIAC, there can be no guarantee that the interest rate a Portfolio receives under such a Funding Agreement will be as favorable to a Portfolio as the rate that might be paid under a Funding Agreement with another, unaffiliated insurer.
The Sub-Adviser’s decision to invest in a Funding Agreement issued by VRIAC presents conflicts of interest. VRIAC will typically invest the proceeds of the Funding Agreement at a spread above what it agrees to pay a Portfolio, resulting in a financial benefit to VRIAC, and the Sub-Adviser receives a management fee from VRIAC for managing the proceeds of the Funding Agreement (along with the proceeds of other funding agreements issued by VRIAC). In addition, an investment in a Funding Agreement may have the effect of reducing a Portfolio’s gross expenses, thereby also reducing the investment adviser’s obligations under fee waiver and expense limitation arrangements with a Portfolio. Any changes in the interest rate paid by VRIAC on a Funding Agreement is determined by VRIAC, with prior notice to a Portfolio. The Sub-Adviser may have a financial incentive to invest a greater percentage of a Portfolio’s assets in a Funding Agreement with VRIAC than the percentage of a Portfolio’s assets it might invest in obligations of any other single issuer, including following a reduction in the interest rate paid on the Funding Agreement. A Portfolio’s affiliation with VRIAC might delay or limit a Portfolio’s ability to recover its investment in a Funding Agreement in the event of an insolvency of VRIAC. The Sub-Adviser is subject to a fiduciary duty to a Portfolio in its decisions as to whether, and how much, a Portfolio should invest in a Funding Agreement with VRIAC at any time. In addition, investments by a Portfolio in a Funding Agreement with VRIAC must comply with conditions set forth in applicable exemptive relief provided by the Securities and Exchange Commission designed to mitigate the foregoing conflicts of interest, and in related policies and procedures adopted by a Portfolio’s Board of Directors.
Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.
High-Yield Securities: Lower quality securities (including securities that have fallen below investment-grade and are classified as “junk bonds” or “high yield securities”) have greater credit risk and liquidity risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.
Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. In particular, when deciding between Underlying Index Funds benchmarked to the same index, the manager will generally select an affiliated Underlying Index Fund, even when the affiliated Underlying Index Fund has higher expenses than an unaffiliated Underlying Index Fund. When the Portfolio invests in an affiliated Underlying Index Fund with higher expenses, the Portfolio’s performance will be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance). The manager may select an unaffiliated Underlying Index Fund, including an exchange-traded fund, over an affiliated Underlying Fund benchmarked to the same index when the manager believes making an investment in the affiliated Underlying Index Fund would be disadvantageous to the affiliated Underlying Index Fund, such as when the Portfolio is investing on a short term basis.
Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as
Voya Index Solution 2035 Portfolio
33

interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.
Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the 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 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.
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.
The Chinese economy is generally considered an emerging and volatile market. 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. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States of America 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 Adviser otherwise believes is attractive, the Portfolio may incur losses.
LIBOR: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based in whole or in part on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including among others a Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. Discontinuance of LIBOR and adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Portfolio’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of an the Portfolio; and the risk of general market disruption during the transition period. Markets relying on new, non-LIBOR rates are developing slowly, and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to other rates could have a substantial adverse impact on the performance of an the Portfolio.
Voya Index Solution 2035 Portfolio

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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.
Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the 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-sized companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in larger 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 larger 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 U.S. Wars, terrorism, global health crises and pandemics, and other geopolitical events have led, and in the future may lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and world economies and markets generally. For example, the COVID-19 pandemic has resulted, and may continue to result, in significant market volatility, exchange trading suspensions and closures, declines in global financial markets, higher default rates, 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 could adversely affect global energy and financial markets and therefore could affect the value of a Portfolio’s investments, including beyond a 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. Those events as well as other changes in 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 investments of the Portfolio and the Portfolio. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio’s service providers.
Natural Resources/Commodity Securities: The operations and financial performance of companies in natural resources industries may be directly affected by commodity prices. This risk is exacerbated for those natural resources companies that own the underlying commodity.
Other Investment Companies: The main risk of investing in other investment companies, including exchange-traded funds (“ETFs”), is the risk that the value of the securities underlying an investment company might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the expenses of the Portfolio. 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.
Prepayment and Extension: Many types of debt instruments are subject to prepayment and extension risk. Prepayment risk is the risk that the issuer of a debt instrument will pay back the principal earlier than expected. This may occur when interest rates decline. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a debt 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 debt instrument will pay back the principal later than expected.
Voya Index Solution 2035 Portfolio
35

This may occur when interest rates rise. This may negatively affect performance, as the value of the debt 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.
Real Estate Companies and Real Estate Investment Trusts (“REITs”): 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, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. Investments in REITs are affected by the management skill and creditworthiness of the REIT. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.
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. A particular risk of the Portfolio’s value approach is that some holdings may not recover and provide the capital growth anticipated or a security judged to be undervalued may actually be appropriately priced. The market may not favor value-oriented securities and may not favor equities at all. During those periods, the Portfolio’s relative performance may suffer. There is a risk that funds that invest in value-oriented stocks may underperform other funds that invest more broadly.
An investment in the 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 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 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 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
Until the day prior to its Target Date (defined below), the Portfolio seeks to provide total return consistent with an asset allocation targeted at retirement in approximately 2040. On the Target Date, the Portfolio's investment objective will be to seek to provide a combination of total return and stability of principal consistent with an asset allocation targeted to retirement.
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.

The adviser is contractually obligated to limit expenses to 0.89%, 0.39%, 0.64%, and 0.79% for Class ADV, Class I, Class S, and Class S2 shares, respectively, through May 1, 2023. The limitation does not extend to interest, taxes, investment-related costs, leverage expenses and extraordinary expenses. Termination or modification of this obligation requires approval by the Portfolio’s board.
Expense Example
The 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 35% 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 a combination of Underlying Funds which are passively managed index funds. The Portfolio will provide shareholders with at least 60 days' prior written notice of any change in this investment policy. The Underlying Funds may or may not be affiliated with the investment adviser. The Underlying Funds invest in U.S. stocks, international stocks, U.S. bonds, and other debt instruments and the Portfolio uses an asset allocation strategy designed for investors expecting to retire around the year 2040. The Portfolio's current approximate target investment allocation (expressed as a percentage of its net assets) (“Target Allocation”) among the Underlying Funds is as follows: 77% in equity securities and 23% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown. In establishing the Portfolio’s exposure to debt instruments, the investment adviser will set target allocations to funding agreements with affiliated or unaffiliated (if available) insurance companies (collectively, “Funding Agreements”), which will not exceed 10% in the case of contracts of any single issuer or 20% for all issuers combined. Because those are target allocations, the Portfolio’ s actual allocations might exceed those percentages at times due to a variety of factors, such as changes in the relative values of the Portfolio’s investments and cash flows into and out of the Portfolio, and at those times the Portfolio will typically continue to invest new cash in accordance with those target allocations.
At least 80% of the Portfolio’s assets will normally be invested in Underlying Funds affiliated with the investment adviser; this amount may include investments in one or more Funding Agreements issued by Voya Retirement Insurance and Annuity Company (“VRIAC”). The sub-adviser (“Sub-Adviser”) may in its discretion invest up to 20% of the Portfolio’s assets in Underlying Funds, including exchange-traded funds, that are not affiliated with the investment adviser and, potentially, in Funding Agreements issued by insurance companies unaffiliated with the investment adviser, should they be available for investment by the Portfolio.
The Target Allocation is measured with reference to the primary investment strategies of the Underlying Funds; actual exposure to debt instruments and equity securities will vary from the Target Allocation depending on the actual investments held by the Underlying Funds. The Sub-Adviser may periodically cause the Portfolio to deviate from the Target Allocation based on its assessment of current market conditions or other factors. Generally, the deviations fall within the range of +/- 10% relative to the current Target Allocation. The Sub-Adviser may determine, in light of market conditions or other factors, to deviate by a wider margin in order to protect the Portfolio, achieve its investment objective, or to take advantage of particular opportunities.
The Underlying Funds provide exposure to a wide range of traditional asset classes which include stocks, bonds and cash.
Equity securities in which the Underlying Funds invest include, but are not limited to, domestic and international large-, mid-, and small-capitalization stocks (may be growth oriented, value oriented or a blend); and emerging market securities.
Debt instruments in which the Underlying Funds invest include, but are not limited to, domestic and international intermediate-, long-, and short-term bonds; high-yield bonds commonly referred to as “junk-bonds”; floating rate loans; and Funding Agreements.
The Portfolio may also invest in derivatives, including futures and swaps (including interest rate swaps, total return swaps, and credit default swaps), to make tactical allocations, as a substitute for taking a position in the underlying asset, to minimize risk, and to assist in managing cash.
The Portfolio may also allocate to the following non-traditional asset classes (also known as alternative strategies) which include but are not limited to: domestic and international real estate-related securities, including real estate investment trusts; natural resource/commodity securities; and treasury inflation protected securities. There can be no assurance that these allocations will occur.
The Portfolio is designed primarily for long-term investors in tax-advantaged accounts. The Portfolio is structured and managed around a specific target retirement or financial goal date of 2040 (“Target Date”). The Target Date is the approximate year that an investor in the Portfolio would plan to make withdrawals from the Portfolio for retirement or other financial goals. The chart below shows the glide path and illustrates how the target allocations to equity securities and debt instruments will change over time. Generally, the Portfolio's glide path will transition to the target asset allocation illustrated below on an annual basis and become more conservative as the Portfolio approaches the Target Date. As the Portfolio approaches its Target Date, the Portfolio's Target Allocation is anticipated to be the same as that of Voya Index Solution Income Portfolio, which is equal to approximately 35% equity securities and 65% debt instruments.
Voya Index Solution 2040 Portfolio
39

As the Portfolio's Target Allocation migrates toward that of Voya Index Solution Income Portfolio by the Target Date, it is anticipated that the Portfolio would be merged with and into the Voya Index Solution Income Portfolio. The Voya Index Solution Income Portfolio is for those investors who are retired, nearing retirement or in need of making withdrawals from their portfolio soon.
In summary, the Portfolio is designed for an investor who plans to withdraw the value of the investor's investments in the Portfolio gradually on or after the Target Date. The mix of investments in the Portfolio's Target Allocation will change over time and seek to reduce investment risk as the Portfolio approaches its Target Date.
The Portfolio will be rebalanced periodically to return to the Target Allocation. The Target Allocation may be changed at any time by the Sub-Adviser.
Principal Risks
You could lose money on an investment in the Portfolio, even near, at, or after the Target Date. There is no guarantee that the Portfolio will provide adequate income at and through your retirement or for any of your financial goals. The value of your investment in the Portfolio changes with the values of the Underlying Funds and their investments. The Portfolio is subject to the following principal risks (either directly or through investments in one or more Underlying Funds). Any of these risks, among others, could affect the Portfolio's or an Underlying Fund's performance or cause the Portfolio or an Underlying Fund to lose money or to underperform market averages of other funds.
Affiliated Underlying Funds: The manager’s selection of Underlying Funds presents conflicts of interest. The net management fee revenue received by the manager and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the manager will have an incentive to select the Underlying Funds (whether or not affiliated with the manager) that will result in the greatest net management fee revenue to the manager and its affiliates, even if that results in increased expenses for the Portfolio. In many cases, investments in affiliated Underlying Funds will afford the manager greater net management fee revenue than would investments in unaffiliated Underlying Funds. In addition, the manager may prefer to invest in an affiliated Underlying Fund over an unaffiliated fund because the investment may be beneficial to the manager in managing the affiliated Underlying Fund, by helping the affiliated Underlying Fund achieve economies of scale or by enhancing cash flows to the affiliated Underlying Fund. In certain circumstances, the manager would have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds and may implement portfolio changes in a manner intended to minimize the disruptive effects and added costs of those changes to affiliated Underlying Funds. Although the Portfolio may invest a portion of its assets in unaffiliated Underlying Funds, there is no assurance that it will do so even in cases where the unaffiliated Underlying Funds incur lower fees than the comparable affiliated Underlying Funds. If the Portfolio invests in an Underlying Fund with higher expenses, the Portfolio’s performance would be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance).
Asset Allocation: Investment performance depends on the manager’s skill in allocating assets among the asset classes in which the Portfolio invests and in choosing investments within those asset classes. There is a risk that the manager may allocate assets or investments to an asset class that underperforms compared to other asset classes or investments.
Cash/Cash Equivalents: Investments in cash or cash equivalents may lower returns and result in potential lost opportunities to participate in market appreciation which could negatively impact the Portfolio’s performance and ability to achieve its investment objective.
Company: The price of a company’s stock could decline or underperform for many reasons including, among others, poor management, financial problems, reduced demand for company goods or services, regulatory fines and judgments, or business challenges. If a company declares bankruptcy or becomes insolvent, its stock could become worthless.
Voya Index Solution 2040 Portfolio

Credit: The price of a bond or other debt instrument is likely to fall if the issuer’s actual or perceived financial health deteriorates, whether because of broad economic or issuer-specific reasons. In certain cases, the issuer could be late in paying interest or principal, or could fail to pay its financial obligations altogether.
Credit Default Swaps: The Portfolio may enter into credit default swaps, either as a buyer or a seller of the swap. A buyer of a swap pays a fee to buy protection against the risk that a security will default. If no default occurs, the Portfolio will have paid the fee, but typically will recover nothing under the swap. A seller of a swap receives payment(s) in return for an obligation to pay the counterparty the full notional value of a security in the event of a default of the security issuer. As a seller of a swap, the Portfolio would effectively add leverage to its portfolio because, in addition to its total net assets, the Portfolio would be subject to investment exposure on the full notional value of the swap. Credit default swaps are particularly subject to counterparty, credit, valuation, liquidity and leveraging risks and the risk that the swap may not correlate with its underlying asset as expected. Certain standardized swaps are subject to mandatory central clearing. Central clearing is expected to reduce counterparty credit risk and increase liquidity; however, there is no assurance that central clearing will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to new kinds of costs and risks. In addition, credit default swaps expose the Portfolio to the risk of improper valuation.
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.
Deflation: Deflation occurs when prices throughout the economy decline over time - the opposite of inflation. When there is deflation, the principal and income of an inflation-protected bond will decline and could result in losses.
Derivative Instruments: Derivative instruments are subject to a number of risks, including the risk of changes in the market price of the underlying securities, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates and liquidity and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the 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 currency, security or other risk being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment. In addition, given their complexity, derivatives expose the Portfolio to the risk of improper valuation.
Floating Rate Loans: In the event a borrower fails to pay scheduled interest or principal payments on a floating rate loan (which can include certain bank loans), the Portfolio will experience a reduction in its income and a decline in the market value of such investment. This will likely reduce the amount of dividends paid and may lead to a decline in the net asset value. If a floating rate loan is held by the Portfolio through another financial institution, or the Portfolio relies upon another financial institution to administer the loan, the receipt of scheduled interest or principal payments may be subject to the credit risk of such financial institution. Investors in floating rate loans may not be afforded the protections of the anti-fraud provisions of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, because loans may not be considered “securities” under such laws. Additionally, the value of collateral, if any, securing a floating rate loan can decline or may be insufficient to meet the issuer’s obligations under the loan. Furthermore, such collateral may be difficult to liquidate. No active trading market may exist for many floating rate loans and many floating rate loans are subject to restrictions on resale. Transactions in loans typically settle on a delayed basis and may take longer than 7 days to settle. As a result, the Portfolio may not receive the proceeds from a sale of a floating rate loan for a significant period of time. Delay in the receipts of settlement proceeds may impair the ability of the Portfolio to meet its redemption obligations. It may also limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.
Foreign 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 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; or political changes or diplomatic developments, which may include the imposition of economic sanctions or other measures by the United States or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign investment risks may be greater in developing and emerging markets than in developed markets.
Voya Index Solution 2040 Portfolio
41

Funding Agreements: A Portfolio may invest in Funding Agreements issued by insurance companies affiliated with the investment adviser and Sub-Adviser, such as VRIAC, and insurance companies unaffiliated with the investment adviser and Sub-Adviser. A Funding Agreement has a stable principal value and typically pays interest at a relatively short-term rate, which is subject to change periodically. Investment in a Funding Agreement is subject to the credit risk of the insurer, and an insurer may be unable to repay the entire amount of principal and interest due under a Funding Agreement. In a rising interest rate environment, the interest rate provided by a Funding Agreement may not increase as quickly as the yields of other short-term investments, adversely affecting a Portfolio’s performance. In the case of a Funding Agreement with VRIAC, there can be no guarantee that the interest rate a Portfolio receives under such a Funding Agreement will be as favorable to a Portfolio as the rate that might be paid under a Funding Agreement with another, unaffiliated insurer.
The Sub-Adviser’s decision to invest in a Funding Agreement issued by VRIAC presents conflicts of interest. VRIAC will typically invest the proceeds of the Funding Agreement at a spread above what it agrees to pay a Portfolio, resulting in a financial benefit to VRIAC, and the Sub-Adviser receives a management fee from VRIAC for managing the proceeds of the Funding Agreement (along with the proceeds of other funding agreements issued by VRIAC). In addition, an investment in a Funding Agreement may have the effect of reducing a Portfolio’s gross expenses, thereby also reducing the investment adviser’s obligations under fee waiver and expense limitation arrangements with a Portfolio. Any changes in the interest rate paid by VRIAC on a Funding Agreement is determined by VRIAC, with prior notice to a Portfolio. The Sub-Adviser may have a financial incentive to invest a greater percentage of a Portfolio’s assets in a Funding Agreement with VRIAC than the percentage of a Portfolio’s assets it might invest in obligations of any other single issuer, including following a reduction in the interest rate paid on the Funding Agreement. A Portfolio’s affiliation with VRIAC might delay or limit a Portfolio’s ability to recover its investment in a Funding Agreement in the event of an insolvency of VRIAC. The Sub-Adviser is subject to a fiduciary duty to a Portfolio in its decisions as to whether, and how much, a Portfolio should invest in a Funding Agreement with VRIAC at any time. In addition, investments by a Portfolio in a Funding Agreement with VRIAC must comply with conditions set forth in applicable exemptive relief provided by the Securities and Exchange Commission designed to mitigate the foregoing conflicts of interest, and in related policies and procedures adopted by a Portfolio’s Board of Directors.
Growth Investing: Prices of growth stocks are more sensitive to investor perceptions of the issuing company’s growth potential and may fall quickly and significantly if investors suspect that actual growth may be less than expected. There is a risk that funds that invest in growth-oriented stocks may underperform other funds that invest more broadly. Growth stocks tend to be more volatile than value stocks, and may underperform the market as a whole over any given time period.
High-Yield Securities: Lower quality securities (including securities that have fallen below investment-grade and are classified as “junk bonds” or “high yield securities”) have greater credit risk and liquidity risk than higher quality (investment-grade) securities, and their issuers' long-term ability to make payments is considered speculative. Prices of lower quality bonds or other debt instruments are also more volatile, are more sensitive to negative news about the economy or the issuer, and have greater liquidity and price volatility risk.
Index Strategy: An Underlying Fund that seeks to track an index’s performance and does not use defensive strategies or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market. To the extent an Underlying Fund’s investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. The correlation between an Underlying Index Fund’s performance and index performance will be reduced by the Underlying Index Fund’s expenses and could be reduced by the timing of purchases and redemptions of the Underlying Index Fund’s shares. In addition, an Underlying Index Fund’s actual holdings might not match the index and an Underlying Index Fund’s effective exposure to index securities at any given time may not precisely correlate. When deciding between Underlying Index Funds benchmarked to the same index, the manager may not select the Underlying Index Fund with the lowest expenses. In particular, when deciding between Underlying Index Funds benchmarked to the same index, the manager will generally select an affiliated Underlying Index Fund, even when the affiliated Underlying Index Fund has higher expenses than an unaffiliated Underlying Index Fund. When the Portfolio invests in an affiliated Underlying Index Fund with higher expenses, the Portfolio’s performance will be lower than if the Portfolio had invested in an Underlying Fund with comparable performance but lower expenses (although any expense limitation arrangements in place at the time might have the effect of limiting or eliminating the amount of that underperformance). The manager may select an unaffiliated Underlying Index Fund, including an exchange-traded fund, over an affiliated Underlying Fund benchmarked to the same index when the manager believes making an investment in the affiliated Underlying Index Fund would be disadvantageous to the affiliated Underlying Index Fund, such as when the Portfolio is investing on a short term basis.
Inflation-Indexed Bonds: If the index measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. In addition, inflation-indexed bonds are subject to the usual risks associated with debt instruments, such as
Voya Index Solution 2040 Portfolio
42

interest rate and credit risk. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds. For bonds that do not provide a similar guarantee, the adjusted principal value of the bond repaid at maturity may be less than the original principal.
Interest Rate: With bonds and other fixed rate debt instruments, a rise in market interest rates generally causes values to fall; conversely, values generally rise as market interest rates fall. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is likely to be to interest rate risk. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. As of the date of this Prospectus, the United States experiences a low interest rate environment, which may increase the Portfolio’s exposure to risks associated with rising market interest rates. Rising market interest rates could have unpredictable effects on the markets and may expose fixed-income and related markets to heightened volatility. To the extent that the Portfolio invests in fixed-income securities, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the 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 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.
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.
The Chinese economy is generally considered an emerging and volatile market. 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. In addition, there may be restrictions on investments in Chinese companies. For example, on November 12, 2020, the President of the United States of America 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 Adviser otherwise believes is attractive, the Portfolio may incur losses.
LIBOR: The obligations of the parties under many financial arrangements, such as debt instruments (including senior loans) and derivatives, may be determined based in whole or in part on the London Inter-Bank Offered Rate (“LIBOR”). In 2017, the UK Financial Conduct Authority announced its intention to cease compelling banks to provide the quotations needed to sustain LIBOR after 2021. ICE Benchmark Administration, the administrator of LIBOR, ceased publication of most LIBOR settings on a representative basis at the end of 2021 and is expected to cease publication of a majority of U.S. dollar LIBOR settings on a representative basis after June 30, 2023. In addition, global regulators have announced that, with limited exceptions, no new LIBOR-based contracts should be entered into after 2021. Actions by regulators have resulted in the establishment of alternative reference rates to LIBOR in many major currencies, including among others a Secured Overnight Funding Rate (“SOFR”) for U.S. dollar LIBOR. Discontinuance of LIBOR and adoption/implementation of alternative rates pose a number of risks, including, among others, whether any substitute rate will experience the market participation and liquidity necessary to provide a workable substitute for LIBOR; the effect on parties’ existing contractual arrangements, hedging transactions, and investment strategies generally from a conversion from LIBOR to alternative rates; the effect on the Portfolio’s existing investments, including the possibility that some of those investments may terminate or their terms may be adjusted to the disadvantage of an the Portfolio; and the risk of general market disruption during the transition period. Markets relying on new, non-LIBOR rates are developing slowly, and may offer limited liquidity. The general unavailability of LIBOR and the transition away from LIBOR to other rates could have a substantial adverse impact on the performance of an the Portfolio.
Voya Index Solution 2040 Portfolio

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 price at which it sells illiquid securities will be less than the price at which they were valued when held by the Portfolio. The prices of illiquid securities may be more volatile than more liquid investments. The risks associated with illiquid securities may be greater in times of financial stress. The Portfolio could lose money if it cannot sell a security at the time and price that would be most beneficial to the Portfolio.
Market: Stock prices may be volatile or have reduced liquidity in response to real or perceived impacts of factors including, but not limited to, economic conditions, changes in market interest rates, and political events. Stock markets tend to be cyclical, with periods when stock prices generally rise and periods when stock prices generally decline. Any given stock market segment may remain out of favor with investors for a short or long period of time, and stocks as an asset class may underperform bonds or other asset classes during some periods. Additionally, legislative, regulatory or tax policies or developments in these areas may adversely impact the investment techniques available to a manager, add to costs and impair the ability of the 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
