Investment Objective

The Portfolio seeks to maximize income while maintaining prospects for capital appreciation.

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 two years of the three-, five-, and ten-year periods. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Portfolio Turnover

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs. These costs, which are not reflected in Annual Portfolio Operating Expenses or in the Expense Example, affect the Portfolio's performance.

During the most recent fiscal year, the Portfolio's portfolio turnover rate was 80% of the average value of its portfolio.

Principal Investment Strategies

Under normal circumstances, the Portfolio intends to invest approximately 60% of its assets in debt instruments and approximately 40% of its assets in equity securities (the "Target Allocation"). The sub-adviser (the "Sub-Adviser") may deviate from the Target Allocation within the range of +/- 15% relative to the Target Allocation for each of equities or debt to adjust portfolio exposures and risk in response to changing market conditions. The Portfolio may be rebalanced periodically to return to the Target Allocation.

Debt Portion

The debt portion of the Portfolio (the "Debt Portion") is not managed relative to an index, instead the Sub-Adviser seeks to produce income and positive returns across varying market conditions. To seek this goal, the Sub-Adviser expects to invest substantially all of the Debt Portion of the Portfolio in actively managed exchange-traded funds ("ETFs") (the "Underlying Funds") affiliated with the Investment Adviser. The Underlying Funds invest across a broad range of debt instruments and derivatives. It is expected that the dollar-weighted average duration profile of the Underlying Funds, in combination, will be between 0 and 8 years. Duration is a commonly used measure of risk in debt instruments as it incorporates multiple features of debt instruments (e.g., yield, coupon, maturity, etc.) into one number. Duration is a measure of sensitivity of the price of a debt instrument to a change in interest rates. Duration is a weighted average of the times that interest payments and the final return of principal are received. The weights are the amounts of the payments discounted by the yield-to-maturity of the debt instrument. Duration is expressed as a number of years. The bigger the duration number, the greater the interest rate risk or reward for the debt instrument prices. For example, the price of a bond with an average duration of 5 years would be expected to fall approximately 5% if market interest rates rose by 1%. Conversely, the price of a bond with an average duration of 5 years would be expected to rise approximately 5% if market interest rates dropped by 1%.

The Underlying Funds may invest in debt instruments rated investment grade and below investment grade (sometimes referred to as "high-yield securities", "high-yield bonds", or "junk bonds"). Investment grade refers to a rating given by one or more nationally recognized statistical rating organizations ("NRSROs") (e.g., rated Baa3 or above by Moody's Ratings ("Moody's"), or BBB- or above by S&P Global Ratings ("S&P") or Fitch Ratings, Inc. ("Fitch")) or, if unrated, determined by the Portfolio to be of comparable quality. Below investment grade refers to a rating given by one or more NRSROs (e.g., rated Ba1 or below by Moody's, or BB+ or below by S&P or Fitch) or, if unrated, determined by the relevant Underlying Fund to be of comparable quality. The Underlying Funds may also invest in floating rate loans, and other floating rate debt instruments.

Debt instruments may be issued by various U.S. and foreign (non-U.S.) public or private sector entities (including those located in emerging market countries). Debt instruments may include, without limitation, bonds, debentures, notes, convertible securities, commercial paper, loans and related assignments and participations, corporate debt, asset- and mortgage-backed securities, preferred stock, bank certificates of deposit, fixed time deposits, bankers' acceptances and money market instruments, including money market funds denominated in U.S. dollars or other currencies. Floating rate loans and other floating rate debt instruments include floating rate bonds, floating rate notes, floating rate debentures, and tranches of floating rate asset-backed securities, including structured notes, made to, or issued by, U.S. and foreign (non-U.S.) corporations or other business entities. The Underlying Funds may also invest in inflation-indexed bonds of varying maturities issued by the U.S. and foreign (non-U.S.) governments, their agencies and instrumentalities, and U.S. and foreign (non-U.S.) corporations.

Equity Portion

The equity portion of the Portfolio (the "Equity Portion") invests in securities of U.S. and foreign (non-U.S.) issuers. The Sub-Adviser seeks to maximize total return of the Equity Portion by investing in a mix of U.S. and foreign (non-U.S.) equity securities with dividend yields the Sub-Adviser believes are attractive and/or above-average growth prospects.

The Equity Portion may also invest in real estate-related securities, including real estate investment trusts ("REITs").

In addition to the investments in the Underlying Funds by the Debt Portion of the Portfolio, the Portfolio may invest in other investment companies, including ETFs, that may or may not be affiliated with the Investment Adviser, to the extent permitted under the Investment Company Act of 1940, as amended, and the rules and regulations thereunder, and under the terms of applicable no-action relief or exemptive orders granted thereunder.

The Portfolio may invest up to 25% of its assets in foreign (non-U.S.) securities, including companies located in emerging markets, either directly or through depositary receipts.

The Portfolio, directly or through Underlying Funds, may also invest in derivatives, including options, futures, index futures, swaps (including interest rate swaps, total return swaps, and credit default swaps), and currency forwards, as a substitute for taking a position in an underlying asset, to make tactical asset allocations, to seek to minimize risk, to enhance returns, and/or to assist in managing cash.

In evaluating investments for the Portfolio, including investments in Underlying Funds, the Sub-Adviser takes into account a wide variety of factors and considerations to determine whether any or all of those factors or considerations might have a material effect on the value, risks, or prospects of an investment. Among the factors considered, the Sub-Adviser expects typically to take into account environmental, social, and governance ("ESG") factors to determine whether one or more factors may have a material effect. In considering ESG factors, the Sub-Adviser intends to rely primarily on factors identified through its proprietary empirical research and on third-party evaluations of an issuer's ESG standing. ESG factors will be only one of many considerations in the Sub-Adviser's evaluation of any potential investment, including an investment in a potential Underlying Fund; the extent to which ESG factors will affect the Sub-Adviser's decision to invest in an issuer or an Underlying Fund, if at all, will depend on the analysis and judgment of the Sub-Adviser.

The Sub-Adviser may sell securities for a variety of reasons, such as to secure gains, limit losses, or redeploy assets into opportunities believed to be more promising.

The Portfolio may lend portfolio securities on a short-term or long-term basis, up to 33 1∕3% of its total assets.

Principal Risks

You could lose money on an investment in the Portfolio. Any of the following risks, among others, could affect Portfolio performance or cause the Portfolio to lose money or to underperform market averages of other funds. The principal risks are presented in alphabetical order to facilitate readability, and their order does not imply that the realization of one risk is more likely to occur or have a greater adverse impact than another risk.

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.

Bank Instruments: Bank instruments include certificates of deposit, fixed time deposits, bankers' acceptances, and other debt and deposit-type obligations issued by banks. Changes in economic, regulatory, or political conditions, or other events that affect the banking industry may have an adverse effect on bank instruments or banking institutions that serve as counterparties in transactions with the Portfolio. In the event of a bank insolvency or failure, the Portfolio may be considered a general creditor of the bank, and it might lose some or all of the funds deposited with the bank. Even where it is recognized that a bank might be in danger of insolvency or failure, the Portfolio might not be able to withdraw or transfer its money from the bank in time to avoid any adverse effects of the insolvency or failure. Volatility in the banking system may impact the viability of banking and financial services institutions. In the event of failure of any of the financial institutions where the Portfolio maintains its cash and cash equivalents, there can be no assurance that the Portfolio would be able to access uninsured funds in a timely manner or at all and the Portfolio may incur losses. Any such event could adversely affect the business, liquidity, financial position and performance of the Portfolio.

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

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

Convertible Securities: Convertible securities are securities that are convertible into or exercisable for common stocks at a stated price or rate. Convertible securities are subject to the usual risks associated with debt instruments, such as interest rate risk and credit risk. In addition, because convertible securities react to changes in the value of the underlying stock, they are subject to market risk.

Covenant-Lite Loans: Loans in which the Portfolio may invest or to which the Portfolio may gain exposure indirectly through its investments in collateralized debt obligations, CLOs or other types of structured securities may be considered "covenant-lite" loans. Covenant-lite refers to loans which do not incorporate traditional performance-based financial maintenance covenants. Covenant-lite does not refer to a loan's seniority in a borrower's capital structure nor to a lack of the benefit from a legal pledge of the borrower's assets and does not necessarily correlate to the overall credit quality of the borrower. Covenant-lite loans generally do not include terms which allow a lender to take action based on a borrower's performance relative to its covenants. Such actions may include the ability to renegotiate and/or re-set the credit spread on the loan with a borrower, and even to declare a default or force the borrower into bankruptcy restructuring if certain criteria are breached. Covenant-lite loans typically still provide lenders with other covenants that restrict a borrower from incurring additional debt or engaging in certain actions. Such covenants can only be breached by an affirmative action of the borrower, rather than by a deterioration in the borrower's financial condition. Accordingly, the Portfolio may have fewer rights against a borrower when it invests in, or has exposure to, covenant-lite loans and, accordingly, may have a greater risk of loss on such investments as compared to investments in, or exposure to, loans with additional or more conventional covenants.

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. Asset-backed (including mortgage-backed) securities that are not issued by U.S. government agencies may have a greater risk of default

because they are not guaranteed by either the U.S. government or an agency or instrumentality of the U.S. government. The credit quality of typical asset-backed securities depends primarily on the credit quality of the underlying assets and the structural support (if any) provided to the securities.

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.

Dividend: Companies that issue dividend yielding equity securities are not required to continue to pay dividends on such securities. Therefore, there is a possibility that such companies could reduce or eliminate the payment of dividends in the future. As a result, the Portfolio's ability to execute its investment strategy may be limited.

Environmental, Social, and Governance (Equity): The Sub-Adviser's consideration of ESG factors in selecting investments for the Portfolio is based on information that is not standardized, some of which can be qualitative and subjective by nature. The Sub-Adviser's assessment of ESG factors in respect of a company may rely on third-party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Portfolio's assets that will be invested in companies that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in companies that compare favorably to other companies on the basis of ESG factors. It is possible that the Portfolio will have less exposure to certain companies due to the Sub-Adviser's assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.

Environmental, Social, and Governance (Fixed Income): The Sub-Adviser's consideration of ESG factors in selecting investments for the Portfolio is based on information that is not standardized, some of which can be qualitative and subjective by nature. The Sub-Adviser's assessment of ESG factors in respect of obligations of an issuer may rely on third-party data that might be incorrect or based on incomplete or inaccurate information. There is no minimum percentage of the Portfolio's assets that will be invested in obligations of issuers that the Sub-Adviser views favorably in light of ESG factors, and the Sub-Adviser may choose not to invest in obligations of issuers that compare favorably to obligations of other issuers on the basis of ESG factors. It is possible that the Portfolio will have less exposure to obligations of certain issuers due to the Sub-Adviser's

assessment of ESG factors than other comparable mutual funds. There can be no assurance that an investment selected by the Sub-Adviser, which includes its consideration of ESG factors, will provide more favorable investment performance than another potential investment, and such an investment may, in fact, underperform other potential investments.

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, where 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.

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.

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 in Loans: The value and the income streams of interests in loans (including participation interests in lease financings and assignments in secured variable or floating rate loans) will decline if borrowers delay payments or fail to pay altogether. A significant rise in market interest rates could increase this risk. Although loans may be fully collateralized when purchased, such collateral may become illiquid or decline in value.

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. 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.

Investment Model: The Sub-Adviser's proprietary investment model may not adequately take into account existing or unforeseen market factors or the interaction among such factors, including changes in how such factors interact, and there is no guarantee that the use of a proprietary investment model will result in effective investment decisions for the Portfolio. Volatility management techniques may not always be successful in reducing volatility, may not protect against market declines, and may limit the Portfolio's participation in market gains, negatively impacting performance even during periods when the market is rising. During sudden or significant market rallies, such underperformance may be significant. Moreover, volatility management strategies may increase portfolio transaction costs, which may increase losses or reduce gains. The Portfolio's volatility may not be lower than that of the Portfolio's Index during all market cycles due to market factors. Portfolios that are actively managed, in whole or in part, according to a quantitative investment model (including models that utilize forms of artificial intelligence, such as machine learning) can perform differently from the market, based on the investment model and the factors used in the analysis, the weight placed on each factor, and changes from the factors' historical trends. Mistakes in the construction and implementation of the investment models (including, for example, data problems and/or software issues) may create errors or limitations that might go undetected or are discovered only after the errors or limitations have negatively impacted performance.

Liquidity: If a security is illiquid, the Portfolio might be unable to sell the security at a time when the Portfolio's manager might wish to sell, or at all. Further, the lack of an established secondary market may make it more difficult to value illiquid securities, exposing the Portfolio to the risk that the prices at which it sells illiquid securities will be less than the prices at which they were valued when held by the Portfolio, which could cause the Portfolio to lose money. The prices of illiquid securities may be more volatile than more liquid securities, and the risks associated with illiquid securities may be greater in times of financial stress. 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, 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. In addition, military action by Russia in Ukraine has, and may continue to, adversely affect global energy and financial markets and therefore could affect the value of the Portfolio's investments, including beyond the Portfolio's direct exposure to Russian issuers or nearby geographic regions. Furthermore, the prolonged conflict between Hamas and Israel, and the potential expansion of the conflict in the surrounding areas and the involvement of other nations in such conflict, such as the Houthi movement's attacks on marine vessels in the Red Sea, could further destabilize the Middle East region and introduce new uncertainties in global markets, including the oil and natural gas markets. The extent and duration of the military action, sanctions, and resulting market disruptions are impossible to predict and 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.

Mortgage- and/or Asset-Backed Securities: Defaults on, or low credit quality or liquidity of, the underlying assets of the asset-backed (including mortgage-backed) securities may impair the value of these securities and result in losses. There may be limitations on the enforceability of any security interest or collateral granted with respect to those underlying assets, and the value of collateral may not satisfy the obligation upon default. These securities also present a higher degree of prepayment and extension risk and interest rate risk than do other types of debt instruments.

Other Investment Companies: The main risk of investing in other investment companies, including ETFs, is the risk that the value of an investment company's underlying investments might decrease. Shares of investment companies that are listed on an exchange may trade at a discount or premium from their net asset value. You will pay a proportionate share of the expenses of those other investment companies (including management fees, administration fees, and custodial fees) in addition to the Portfolio's expenses. The investment policies of the other investment companies may not be the same as those of the Portfolio; as a result, an investment in the other investment companies may be subject to additional or different risks than those to which the Portfolio is typically subject. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF's shares, which could cause a material decline in the ETF's net asset value.

Portfolio Turnover: A high portfolio turnover rate may increase transaction costs, which may lower the Portfolio's performance and may increase the likelihood of capital gains distributions.

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.

Securities Lending: Securities lending involves two primary risks: "investment risk" and "borrower default risk." When lending securities, the Portfolio will receive cash or U.S. government securities as collateral. Investment risk is the risk that the Portfolio will lose money from the investment of the cash collateral received from the borrower. Borrower default risk is the risk that the Portfolio will lose money due to the failure of a borrower to return a borrowed security. Securities lending may result in leverage. The use of leverage may exaggerate any increase or decrease in the net asset value, causing the Portfolio to be more volatile. The use of leverage may increase expenses and increase the impact of the Portfolio's other risks.

Sovereign Debt: Sovereign debt is issued or guaranteed by foreign (non-U.S.) government entities. Investments in sovereign debt are subject to the risk that a government entity may delay payment, restructure its debt, or refuse to pay interest or repay principal on its sovereign debt due to cash flow problems, insufficient foreign currency reserves, political considerations, social changes, the relative size of its debt position to its economy, or its failure to put in place economic reforms required by the International Monetary Fund or other multilateral agencies. If a government entity defaults, it may ask for more time in which to pay or for further loans. There is no legal process for collecting amounts owed on sovereign debt, such as bankruptcy proceedings, that a government does not pay.

U.S. Government Securities and Obligations: U.S. government securities are obligations of, or guaranteed by, the U.S. government, its agencies, or government-sponsored enterprises. U.S. government securities are subject to market risk and interest rate risk, and may be subject to varying degrees of credit risk.

Underlying Funds: Because the Portfolio invests in Underlying Funds, the investment performance of the Debt Portion 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.

Since the Underlying Funds are ETFs, such investment would be subject to additional risks, which include that: (i) an active trading market for an ETF's shares may not develop or be maintained; or (ii) trading may be halted if the listing exchanges' officials deem such action appropriate, the shares are delisted from an exchange, or the activation of market-wide "circuit breakers" (which are tied to large decreases in stock prices) halts trading of an ETF's shares. In addition, shares of ETFs may trade at a premium or discount to net asset value and are subject to secondary market trading risks. Secondary markets may be subject to irregular trading activity, wide bid/ask spreads, and extended trade settlement periods in times of market stress because market makers and authorized participants may step away from making a market in an ETF's shares, which could cause a material decline in the ETF's net asset value.

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. 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.

The Portfolio's performance prior to July 9, 2021 reflects returns achieved pursuant to different principal investment strategies. The Portfolio's performance prior to May 1, 2019 reflects returns achieved by a different sub-adviser and pursuant to different principal investment strategies. If the Portfolio's current sub-adviser and principal investment strategies had been in place for the prior periods, the performance information shown would have been different.

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) 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.
