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 Qualified Plan or consult your plan administrator.

Expense Example

This Example is intended to help you compare the cost of investing in shares of the Portfolio with the costs of investing in other mutual funds. The Example does not reflect expenses and charges which are, or may be, imposed under your Variable Contract or Qualified Plan. The Example assumes that you invest $10,000 in the Portfolio for the time periods indicated. The Example also assumes that your investment had a 5% return each year and that the Portfolio's operating expenses remain

the same. The Example reflects applicable expense limitation agreements and/or waivers in effect, if any, for the one-year period and the first year of the time periods indicated. 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.

Principal Investment Strategies

The Portfolio invests primarily in a combination of actively managed funds and passively managed index funds, including exchange-traded funds ("ETFs") (collectively, the "Underlying Funds"). 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) (the "Target Allocation") among the Underlying Funds is: 70% in equity securities and 30% in debt instruments. Although this is the Target Allocation, the actual allocation of the Portfolio's assets may deviate from the percentages shown.

The Portfolio normally invests at least 80% of its assets in Underlying Funds affiliated with the Investment Adviser, although the sub-adviser (the "Sub-Adviser") may in its discretion invest up to 20% of the Portfolio's assets in Underlying Funds that are not affiliated with the Investment Adviser.

The Target Allocation is measured with reference to the principal investment strategies of the Underlying Funds; actual exposure to equity securities and debt instruments will vary from the Target Allocation if an Underlying Fund is not substantially invested in accordance with its principal investment strategy. The Portfolio will deviate from the Target Allocation based on an assessment of the 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, but are not limited to the following: stocks, bonds, and cash and non-traditional asset classes (also known as alternative strategies) which include, but are not limited to: real estate, commodities, and floating rate loans.

Equity securities in which the Underlying Funds invest include, but are not limited to the following: domestic and international large-, mid-, and small-capitalization stocks (which may be growth oriented, value oriented, or a blend); emerging market securities; domestic and international real estate-related securities, including real estate investment trusts ("REITs"); and natural resource/commodity securities.

Debt instruments in which the Underlying Funds invest include, but are not limited to the following: domestic and international long-, intermediate-, and short-term bonds; bonds rated below investment grade (sometimes referred to as "high-yield securities", "high-yield bonds", or "junk bonds"); floating rate loans; and U.S. Treasury Inflation-Protected Securities.

When investing in Underlying Funds, the Sub-Adviser takes into account a wide variety of factors and considerations, including among other things the investment strategy employed in the management of a potential Underlying Fund, and the extent to which an Underlying Fund's investment adviser considers environmental, social, and governance ("ESG") factors as part of its investment process. The manner in which an investment adviser uses ESG factors in its investment process will be only one of many considerations in the Sub-Adviser's evaluation of any potential Underlying Fund, and the extent to which the consideration of ESG factors by an investment adviser will affect the Sub-Adviser's decision to invest in an Underlying Fund, if at all, will depend on the analysis and judgment of the Sub-Adviser.

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 asset allocations, to seek to minimize risk, and to assist in managing cash.

The Portfolio may also allocate in the future to the following asset class: emerging markets debt instruments. There can be no assurance that this allocation 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 (the "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 Allocation to equity securities and debt instruments will change over time. Generally, the Portfolio's glide path will transition to the target 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 in 2040, the Portfolio's Target Allocation is anticipated to be the same as that of Voya Solution Income Portfolio, which is equal to approximately 35% equity securities and 65% debt instruments.

 

As the Portfolio's Target Allocation migrates toward that of Voya Solution Income Portfolio, by the Target Date, it is anticipated that the Portfolio would be merged with and into Voya Solution Income Portfolio. Voya Solution Income Portfolio uses an asset allocation strategy designed for investors who are expecting to retire soon, are already retired, or who are 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 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 indirectly 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. The Portfolio is exposed to most of the principal risks indirectly through investments by the Underlying Funds, and in some cases only through such investments. Unless stated otherwise, in the risk disclosures below, descriptions of investments or activities by "the Portfolio" and related risks refer to investments or activities by the Portfolio or by an Underlying Fund, as the case may be. Similarly, a reference to "the Investment Adviser" or to "the Sub-Adviser" is to the entity responsible for the investments in question, whether by the Portfolio or by an Underlying Fund. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.

Affiliated Underlying Funds: The Sub-Adviser's selection of Underlying Funds presents conflicts of interest. The net management fee revenue received or costs incurred by the Sub-Adviser and its affiliates will vary depending on the Underlying Funds it selects for the Portfolio, and the Sub-Adviser will have an incentive to select the Underlying Funds (whether or not affiliated with the Sub-Adviser) that will result in the greatest net management fee revenue or lowest costs to the Sub-Adviser and its affiliates, even if that results in increased expenses and potentially less favorable investment performance for the Portfolio. The Sub-Adviser may prefer to invest in an affiliated Underlying Fund over an unaffiliated Underlying Fund because the investment may be beneficial to the Sub-Adviser 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. For similar reasons, the Sub-Adviser may have an incentive to delay or decide against the sale of interests held by the Portfolio in affiliated Underlying Funds, and the Sub-Adviser may implement Underlying Fund 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 or have achieved better historical investment performance than the comparable affiliated Underlying Funds.

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 or within an asset class that underperforms compared to other asset classes or investments. The Portfolio may underperform funds that allocate their assets differently than the Portfolio, due to differences in the relative performance of asset classes and subsets of asset classes.

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.

China Investing Risks: The Chinese economy is generally considered an emerging and volatile market. Although China has experienced a relatively stable political environment in recent years, there is no guarantee that such stability will be maintained in the future. Significant portions of the Chinese securities markets may become rapidly illiquid because Chinese issuers have the ability to suspend the trading of their equity securities under certain circumstances, and have shown a willingness to exercise that option in response to market volatility, epidemics, pandemics, adverse economic, market or political events, and other events. Political, regulatory and diplomatic events, such as the U.S.-China "trade war" that intensified in 2018, could have an adverse effect on the Chinese or Hong Kong economies and on related investments. In addition, U.S. or foreign government restrictions on investments in Chinese companies or other intervention could negatively affect the implementation of the Portfolio's investment strategies, such as by precluding the Portfolio from making certain investments or causing the Portfolio to sell investments at disadvantageous times.

Commodities: Commodity prices can have significant volatility, and exposure to commodities can cause the net asset value of the Portfolio's shares to decline or fluctuate in a rapid and unpredictable manner. A liquid secondary market may not exist for certain commodity-related investments, which may make it difficult for the Portfolio to sell them at a desirable price or time.

Company: The price of a company's stock could decline or underperform for many reasons, including, among others, poor management, financial problems, reduced demand for the company's goods or services, regulatory fines and judgments, or business challenges. If a company is unable to meet its financial obligations, declares bankruptcy, or becomes insolvent, its stock could become worthless.

Credit: The Portfolio could lose money if the issuer or guarantor of a debt instrument in which the Portfolio invests, or the counterparty to a derivative contract the Portfolio entered into, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services, or otherwise) as unable or unwilling, to meet its financial obligations.

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 credit default swap is generally obligated to pay the seller an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference obligation has occurred. If a credit event occurs, the seller generally must pay the buyer the "par value" (full notional value) of the swap in exchange for an equal face amount of deliverable obligations of the reference entity described in the swap, or the seller may be required to deliver the related net cash amount if the swap is cash settled. As a seller of a credit default 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 reference obligation as expected. Certain standardized credit default 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 it will achieve that result, and in the meantime, central clearing and related requirements expose the Portfolio to different 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. Unless repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed, 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 asset, reference rate, or index, credit risk with respect to the counterparty, risk of loss due to changes in market interest rates, liquidity risk, valuation risk, and volatility risk. The amounts required to purchase certain derivatives may be small relative to the magnitude of exposure assumed by the Portfolio. Therefore, the purchase of certain derivatives may have an economic leveraging effect on the Portfolio and exaggerate any increase or decrease in the net asset value. Derivatives may not perform as expected, so the Portfolio may not realize the intended benefits. When used for hedging purposes, the change in value of a derivative may not correlate as expected with the asset, reference rate, or index being hedged. When used as an alternative or substitute for direct cash investment, the return provided by the derivative may not provide the same return as direct cash investment.

Environmental, Social, and Governance (Funds-of-Funds): The Sub-Adviser's consideration of ESG factors in selecting Underlying Funds for investment by the Portfolio is based on information that is not standardized, some of which can be qualitative and subjective by nature. There is no minimum percentage of the Portfolio's assets that will be allocated to Underlying Funds on the basis of ESG factors, and the Sub-Adviser may choose to select Underlying Funds on the basis of factors or considerations other than ESG factors. It is possible that the Portfolio will have less exposure to ESG-focused strategies than other comparable mutual funds. There can be no assurance that an Underlying Fund selected by the Sub-Adviser, which includes its consideration of ESG factors, when available, will provide more favorable investment performance than another potential Underlying Fund, and such an Underlying Fund may, in fact, underperform other potential Underlying Funds.

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 floating rate loan. 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 borrower's obligations under the loan, and 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, and may limit the ability of the Portfolio to repay debt, pay dividends, or to take advantage of new investment opportunities.

Foreign (Non-U.S.) Investments/Developing and Emerging Markets: Investing in foreign (non-U.S.) securities may result in the Portfolio experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies due, in part, to: smaller markets; differing reporting, accounting, auditing and financial reporting standards and practices; nationalization, expropriation, or confiscatory taxation; foreign currency fluctuations, currency blockage, or replacement; potential for default on sovereign debt; and political changes or diplomatic developments, which may include the imposition of economic sanctions (or the threat of new or modified sanctions) or other measures by the U.S. or other governments and supranational organizations. Markets and economies throughout the world are becoming increasingly interconnected, and conditions or events in one market, country or region may adversely impact investments or issuers in another market, country or region. Foreign (non-U.S.) investment risks may be greater in developing and emerging markets than in developed markets.

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

High-Yield Securities: Lower-quality securities including securities that are or have fallen below investment grade (commonly referred to as "junk bonds") 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 risk and price volatility.

Index Strategy (Funds-of-Funds): An Underlying Fund (or a portion of the Underlying Fund) that seeks to track an index's performance and does not use defensive positions or attempt to reduce its exposure to poor performing securities in an index may underperform the overall market (each, an "Underlying Index Fund"). To the extent an Underlying Index Fund's investments track its target index, such Underlying Index Fund may underperform other funds that invest more broadly. Errors in index data, index computations or the construction of the index in accordance with its methodology may occur from time to time and may not be identified and corrected by the index provider for a period of time or at all, which may have an adverse impact on the Portfolio. The correlation between an Underlying Index Fund's performance and index performance may be affected by the timing of purchases and redemptions of the Underlying Index Fund's shares. 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 Index 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 ETF, over an affiliated Underlying Index 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 bonds (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: A rise in market interest rates generally results in a fall in the value of bonds and other debt instruments; conversely, values generally rise as market interest rates fall. Interest rate risk is generally greater for debt instruments than floating-rate instruments. The higher the credit quality of the instrument, and the longer its maturity or duration, the more sensitive it is to changes in market interest rates. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rate. The U.S. Federal Reserve Board recently lowered interest rates following a period of consistent rate increases. Declining market interest rates increase the likelihood that debt instruments will be pre-paid. Rising market interest rates have unpredictable effects on the markets and may expose debt and related markets to heightened volatility. To the extent that the Portfolio invests in debt instruments, an increase in market interest rates may lead to increased redemptions and increased portfolio turnover, which could reduce liquidity for certain investments, adversely affect values, and increase costs. Increased redemptions may cause the Portfolio to liquidate portfolio positions when it may not be advantageous to do so and may lower returns. If dealer capacity in debt markets is insufficient for market conditions, it may further inhibit liquidity and increase volatility in debt markets. Fiscal, economic, monetary, or other governmental policies or measures have in the past, and may in the future, cause or exacerbate risks associated with interest rates, including changes in 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 debt and related markets to heightened volatility. In the case of inverse debt instruments, the interest rate paid by the debt instruments is a floating rate, which will generally decrease when the market rate of interest to which the inverse debt instruments are

indexed increases and will increase when the market rate of interest to which the inverse debt instruments are indexed decreases. Changes to monetary policy by the U.S. Federal Reserve Board or other regulatory actions could expose debt and related markets to heightened volatility, interest rate sensitivity, and reduced liquidity, which may impact the Portfolio's operations and return potential.

Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio's manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Portfolio to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Portfolio, which could cause the Portfolio to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress. Certain securities that are liquid when purchased may later become illiquid, particularly in times of overall economic distress or due to geopolitical events such as sanctions, trading halts, or wars. In addition, markets or securities may become illiquid quickly.

Market: The market values of securities will fluctuate, sometimes sharply and unpredictably, based on overall economic conditions, governmental actions or intervention, market disruptions caused by trade disputes or other factors, political developments, and other factors. Prices of equity securities tend to rise and fall more dramatically than those of debt instruments. Additionally, legislative, regulatory or tax policies or developments may adversely impact the investment techniques available to a manager, add to costs, and impair the ability of the Portfolio to achieve its investment objectives.

Market Capitalization: Stocks fall into three broad market capitalization categories: large, mid, and small. Investing primarily in one category carries the risk that, due to current market conditions, that category may be out of favor with investors. If valuations of large-capitalization companies appear to be greatly out of proportion to the valuations of mid- or small-capitalization companies, investors may migrate to the stocks of mid- and small-capitalization companies causing a fund that invests in these companies to increase in value more rapidly than a fund that invests in large-capitalization companies. Investing in mid- and small-capitalization companies may be subject to special risks associated with narrower product lines, more limited financial resources, smaller management groups, more limited publicly available information, and a more limited trading market for their stocks as compared with large-capitalization companies. As a result, stocks of mid- and small-capitalization companies may be more volatile and may decline significantly in market downturns.

Market Disruption and Geopolitical: The Portfolio is subject to the risk that geopolitical events will disrupt securities markets and adversely affect global economies and markets. Due to the increasing interdependence among global economies and markets, conditions in one country, market, or region might adversely impact markets, issuers and/or foreign exchange rates in other countries, including the United States. Wars, terrorism, global health crises and pandemics, trade disputes, tariffs and other restrictions on trade or economic sanctions, rapid technological developments (such as artificial intelligence technologies), and other geopolitical events that have led, and may continue to lead, to increased market volatility and may have adverse short- or long-term effects on U.S. and global economies and markets, generally. For example, the COVID-19 pandemic resulted in significant market volatility, exchange suspensions and closures, declines in global financial markets, higher default rates, supply chain disruptions, and a substantial economic downturn in economies throughout the world. The economic impacts of COVID-19 have created a unique challenge for real estate markets. Many businesses have either partially or fully transitioned to a remote-working environment and this transition may negatively impact the occupancy rates of commercial real estate over time. Natural and environmental disasters and systemic market dislocations are also highly disruptive to economies and markets. Military action by Russia in Ukraine, the prolonged conflict between Hamas and Israel, the Iranian conflict that commenced in February 2026, and political upheaval in Venezuela have resulted, and may continue to result, in sanctions, market disruptions, declines in regional and global stock markets, unusual volatility in global commodity markets, and disruptions to energy production or transportation, including through key shipping routes, any of which could adversely affect the value of the Portfolio's investments, including beyond the Portfolio's direct exposure to issuers in the affected regions. The escalation or expansion of hostilities including the involvement of additional nations, could introduce further uncertainty and volatility in global energy, commodity, and financial markets. The extent and duration of these conflicts, related sanctions, and resulting market disruptions are impossible to predict but could be substantial. A number of U.S. domestic banks and foreign (non-U.S.) banks have experienced financial difficulties and, in some cases, failures. There can be no certainty that the actions taken by regulators to limit the effect of those financial difficulties and failures on other banks or other financial institutions or on the U.S. or foreign (non-U.S.) economies generally will be successful. It is possible that more banks or other financial institutions will experience financial difficulties or fail, which may affect adversely other U.S. or foreign (non-U.S.) financial institutions and economies. These events as well as other changes in foreign (non-U.S.) and domestic economic, social, and political conditions also could adversely affect individual issuers or related groups of issuers, securities markets, interest rates, credit ratings, inflation, investor sentiment, and other factors affecting the value of the Portfolio's investments. Any of these occurrences could disrupt the operations of the Portfolio and of the Portfolio's service providers. Recent technological developments in, and the increasingly widespread use of, artificial intelligence, including machine learning technology and generative artificial intelligence ("AI"), may pose risks

to the Portfolio. For instance, the economy may be significantly impacted by the advanced development and increased regulation of AI. As AI is used more widely, the profitability and growth of Portfolio holdings may be impacted, which could significantly impact the overall performance of the Portfolio. The legal and regulatory frameworks within which AI operates continue to rapidly evolve, and it is not possible to predict the full extent of current or future risks related thereto.

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.

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 risk is heightened in a falling market interest rate environment. Prepayment may expose the Portfolio to a lower rate of return upon reinvestment of principal. Also, if a 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 risk is heightened in a rising market interest rate environment. 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: Investing in real estate companies and REITs may subject the Portfolio to risks similar to those associated with the direct ownership of real estate, including losses from casualty or condemnation, changes in local and general economic conditions, supply and demand, market interest rates, zoning laws, regulatory limitations on rents, property taxes, overbuilding, high foreclosure rates, and operating expenses in addition to terrorist attacks, wars, or other acts that destroy real property. In addition, REITs may also be affected by tax and regulatory requirements in that a REIT may not qualify for favorable tax treatment or regulatory exemptions. Investments in REITs are affected by the management skill of the REIT's sponsor. The Portfolio will indirectly bear its proportionate share of expenses, including management fees, paid by each REIT in which it invests.

Underlying Funds: Because the Portfolio invests primarily in Underlying Funds, the investment performance of the Portfolio is directly related to the investment performance of the Underlying Funds in which it invests. When the Portfolio invests in an Underlying Fund, it is exposed indirectly to the risks of a direct investment in the Underlying Fund. If the Portfolio invests a significant portion of its assets in a single Underlying Fund, it may be more susceptible to risks associated with that Underlying Fund and its investments than if it invested in a broader range of Underlying Funds. It is possible that more than one Underlying Fund will hold securities of the same issuers, thereby increasing the Portfolio's indirect exposure to those issuers. It also is possible that one Underlying Fund may be selling a particular security when another is buying it, producing little or no change in exposure but generating transaction costs and/or resulting in realization of gains with no economic benefit. There can be no assurance that the investment objective of any Underlying Fund will be achieved. In addition, the Portfolio's shareholders will indirectly bear their proportionate share of the Underlying Funds' fees and expenses, in addition to the fees and expenses of the Portfolio itself.

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

An investment in the Portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency.

Performance Information

The following information is intended to help you understand the risks of investing in the Portfolio. The following bar chart shows the changes in the Portfolio's performance from year to year, and the table compares the Portfolio's performance to the performance of a broad-based securities market index and additional indices with investment characteristics similar to those of the Portfolio for the same period. In 2024, the Investment Adviser changed the Portfolio's primary benchmark from the S&P Target Date 2040 Index to the MSCI All Country World IndexSM ("MSCI ACWI") and the Bloomberg U.S. Aggregate Bond Index in accordance with changes to regulatory disclosure requirements. The Portfolio continues to use the S&P Target Date 2040 Index as an additional benchmark that the Investment Adviser believes more closely reflects the Portfolio's principal

investment strategies. 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 U.S. federal income tax purposes. See the Variable Contract prospectus or the governing documents of your Qualified Plan for information regarding the U.S. federal income tax treatment of the distributions to your Variable Contract or Qualified Plan and the holders of the contracts or plan participants.

Payments to Broker-Dealers and Other Financial Intermediaries

If you invest in the Portfolio through a Variable Contract issued by an insurance company or through a Qualified Plan that, in turn, was purchased or serviced through an insurance company, broker-dealer or other financial intermediary, the Portfolio and its Investment Adviser or distributor or their affiliates may: (1) make payments to the insurance company issuer of the Variable Contract or to the company servicing the Qualified Plan and (2) make payments to the insurance company, broker-dealer, or other financial intermediary. These payments may create a conflict of interest by: (1) influencing the insurance company or the company servicing the Qualified Plan to make the Portfolio available as an investment option for the Variable Contract or the Qualified Plan or (2) 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.
