**Transamerica 60/40 Allocation VP** <br>

**Summary Prospectus May 1, 2026**

------

Class Service (No Ticker)

This summary prospectus is designed to provide shareholders with key portfolio information in a clear and concise format. Before you invest, you may want to review the portfolio's prospectus, which contains more information about the portfolio and its risks. You can find the portfolio's prospectus, reports to shareholders, and other information about the portfolio, including the portfolio's statement of additional information, online at https://www.transamerica.com/financial-pro/annuities/prospectus. You can also get this information at no cost by calling 866-414-6349 or by sending an e-mail request to orders@mysummaryprospectus.com, or from your financial professional. The portfolio's prospectus and statement of additional information, both dated May 1, 2026, as supplemented from time to time, are incorporated by reference into this summary prospectus.

**Investment Objective:** Seeks long-term capital appreciation and current income.

**Fees and Expenses:** This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the portfolio, but it does not reflect any charges that are, or may be, imposed under your variable life insurance policy or variable annuity contract. If such charges were reflected, fees would be higher.

------

**Shareholder Fees (fees paid directly from your investment)** 

---

| | |
|:---|:---|
| **Class:** | **Service** |
| Maximum sales charge (load) imposed on purchases (as a <br> percentage of offering price)<br>| None |
| Maximum deferred sales charge (load) (as a percentage of <br> purchase price or redemption proceeds, whichever is lower)<br>| None |

---

**Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)** 

---

| | |
|:---|:---|
| **Class:** | **Service** |
| Management fees | 0.30% |
| Distribution and service (12b-1) fees | 0.25% |
| Other expenses<sup>1</sup> <br>| 0.07% |
| Acquired fund fees and expenses<sup>2</sup> <br>| 0.25% |
| Total annual fund operating expenses | 0.87% |
| Fee waiver and/or expense reimbursement<sup>3</sup> <br>| 0.18% |
| Total annual fund operating expenses after fee waiver and/or <br> expense reimbursement<br>| 0.69% |

---

Total annual fund operating expenses do not correlate to the ratios of expenses to average net assets in the Financial Highlights table, which include overdraft charges that are considered extraordinary expenses. Had these extraordinary expenses been included, Other Expenses would have been 0.08% for Service Class shares.

Acquired fund fees and expenses reflect the portfolio's pro rata share of the fees and expenses incurred by investing in other investment companies. Acquired fund fees and expenses are not included in the calculation of the ratios of expenses to average net assets shown in the Financial Highlights section of the portfolio's prospectus.

Transamerica Asset Management, Inc. ("TAM"), the portfolio's investment manager, has contractually agreed to waive 0.18% of its management fee through May 1, 2027. TAM's contractual waiver cannot be terminated before May 1, 2027 without the consent of the Board of Trustees and is not subject to recapture by TAM.

**Example:** This Example is intended to help you compare the cost of investing in the portfolio with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the portfolio for the time periods indicated and then redeem all shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the portfolio's operating expenses remain the same. The Example does not reflect charges that are, or may be, imposed under your variable life insurance policy or variable annuity contract. If such charges were reflected, costs would be higher. The Example reflects applicable waivers and/or reimbursements for the duration of such arrangement(s). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **1 year** | **3 years** | **5 years** | **10 years** |
| Service Class | &nbsp;&nbsp; $70 | &nbsp;&nbsp; $260 | &nbsp;&nbsp; $465 | &nbsp;&nbsp; $1056 |

---

**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 Example, affect the portfolio's performance.

During the most recent fiscal year, the portfolio turnover rate for the portfolio was 14% of the average value of its portfolio.

**Principal Investment Strategies:** The portfolio is a fund of funds. The portfolio invests its assets in a combination of Transamerica funds ("underlying portfolios"). Transamerica Asset Management, Inc. (the "Investment Manager") selects the underlying portfolios, and determines the amount invested in each of them, based on the portfolio's investment objective, and may make changes from time to time without notice and without shareholder approval.

Under normal circumstances, the portfolio expects to allocate its assets among underlying portfolios with the goal of achieving exposure targets over time of approximately 60% of its net assets in equities and approximately 40% of its net assets in fixed-income. In the short-term, actual asset allocations may vary.

Each underlying portfolio has its own investment objective, principal investment strategies and investment risks. The underlying portfolios may invest in derivatives such as futures contracts, options and swaps. The sub-adviser for each underlying portfolio decides which securities to purchase and sell for that underlying portfolio. The portfolio's ability to achieve its investment objective depends largely on the performance of the underlying portfolios in which it invests.

------

The portfolio may be a significant shareholder in certain underlying portfolios and/or may invest a significant percentage of its assets in one or more underlying portfolios. The portfolio may invest in a limited number of underlying portfolios.

**Principal Risks:** Risk is inherent in all investing. Many factors and risks affect the portfolio's performance, including those described below. The value of your investment in the portfolio, as well as the amount of return you receive on your investment, may fluctuate significantly day to day and over time. You may lose part or all of your investment in the portfolio or your investment may not perform as well as other similar investments. The portfolio, through its investments in underlying portfolios, is subject to the risks of the underlying portfolios. The following is a summary description of principal risks (in alphabetical order after certain key risks) of investing in the portfolio (either directly or through its investments in underlying portfolios). Each risk described below may not apply to each underlying portfolio and an underlying portfolio may be subject to additional or different risks than those described below. The relative significance of the key risks below may change over time and you should review each risk factor carefully. An investment in the portfolio is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. **You may lose money if you invest in this portfolio.**

**Market** – The market prices of the portfolio's securities or other assets may go up or down, sometimes rapidly or unpredictably, due to factors such as economic events, inflation, changes in interest rates, governmental actions or interventions, actions taken by the U.S. Federal Reserve or foreign central banks, market disruptions caused by tariffs, trade disputes, labor strikes, supply chain disruptions or other factors, government shutdowns, political developments, civil unrest, acts of terrorism, armed conflicts, economic sanctions, countermeasures in response to sanctions, cybersecurity events, technological developments (such as artificial intelligence and machine learning), investor sentiment, the global and domestic effects of widespread or local health, weather or climate events, and other factors that may or may not be related to the issuer of the security or other asset. The market price of a security may also fall due to specific conditions that affect a particular sector of the securities market, a particular industry or a particular issuer or group of issuers. To the extent that securities of certain issuers behave or are perceived to behave similarly to each other, the market prices of those securities (or the market as a whole) may fall in response to a decline in the price of a particular security or group of securities. If the market prices of the portfolio's securities and assets fall, the value of your investment in the portfolio could go down.

Economies and financial markets throughout the world are increasingly interconnected. Events or circumstances in one or more countries or regions could be highly disruptive to, and have profound impacts on, global economies or markets. As a result, whether or not the portfolio invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the portfolio's investments may go down.

The long-term consequences to the U.S. economy of the continued expansion of U.S. government debt and deficits are not known. Also, raising the ceiling on U.S. government debt and

periodic legislation to fund the government have become increasingly politicized. Any failure to do either could lead to a default on U.S. government obligations, with unpredictable consequences for the portfolio's investments, and generally for economies and markets in the U.S. and elsewhere.

**Asset Allocation –** The portfolio's investment performance is significantly impacted by the portfolio's asset allocation and reallocation from time to time. The value of your investment may decrease if the Investment Manager's judgment about the attractiveness, value or market trends affecting a particular asset class, investment style, technique or strategy, underlying portfolio or other issuer is incorrect.

**Underlying Portfolios** – Because the portfolio invests its assets in various underlying portfolios, its ability to achieve its investment objective depends largely on the performance of the underlying portfolios in which it invests. Investing in underlying portfolios subjects the portfolio to the risks of investing in the underlying securities or assets held by those underlying portfolios. Each of the underlying portfolios in which the portfolio may invest has its own investment risks, and those risks can affect the value of the underlying portfolios' shares and therefore the value of the portfolio's investments. There can be no assurance that the investment objective of any underlying portfolio will be achieved. To the extent that the portfolio invests more of its assets in one underlying portfolio than in another, the portfolio will have greater exposure to the risks of that underlying portfolio. In addition, the portfolio will bear a pro rata portion of the operating expenses of the underlying portfolios in which it invests. The "List and Description of Underlying Portfolios" section of the portfolio's prospectus identifies certain risks of each underlying portfolio.

**Equity Securities** – Equity securities generally have greater risk of loss than debt securities. Stock markets are volatile and the value of equity securities may go up or down, sometimes rapidly and unpredictably. The market price of an equity security may fluctuate based on overall market conditions, such as real or perceived adverse economic or political conditions or trends, tariffs and trade disruptions, wars, social unrest, inflation, substantial economic downturn or recession, changes in interest rates, or adverse investor sentiment. The market price of an equity security also may fluctuate based on real or perceived factors affecting a particular industry or industries or the company itself. If the market prices of the equity securities owned by the portfolio fall, the value of your investment in the portfolio will decline. The portfolio may lose its entire investment in the equity securities of an issuer. A change in financial condition or other event affecting a single issuer may adversely impact securities markets as a whole.

**Foreign Investments** – Investing in securities of foreign issuers or issuers with significant exposure to foreign markets involves additional risks. Foreign markets can be less liquid, less regulated, less transparent and more volatile than U.S. markets. The value of the portfolio's foreign investments may decline, sometimes rapidly or unpredictably, because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable government actions, including nationalization, expropriation or confiscatory taxation, reduction of government or central bank support, tariffs and trade disruptions, sanctions, political or financial instability, social unrest or other adverse economic or political developments. Foreign investments may also be subject to different

------

accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value than investments in U.S. issuers. Certain foreign clearance and settlement procedures may result in an inability to execute transactions or delays in settlement.

**Fixed-Income Securities** – Risks of fixed-income securities include credit risk, interest rate risk, counterparty risk, prepayment risk, extension risk, valuation risk, and liquidity risk. The value of fixed-income securities may go up or down, sometimes rapidly and unpredictably, due to general market conditions, such as real or perceived adverse economic or political conditions, tariffs and trade disruptions, wars, social unrest, inflation, changes in interest rates, lack of liquidity in the bond markets or adverse investor sentiment. In addition, the value of a fixed-income security may decline if the issuer or other obligor of the security fails to pay principal and/or interest, otherwise defaults or has its credit rating downgraded or is perceived to be less creditworthy, or the credit quality or value of any underlying assets declines. If the value of fixed-income securities owned by the portfolio falls, the value of your investment will go down. The portfolio may lose its entire investment in the fixed-income securities of an issuer.

**Interest Rate** –The value of fixed-income securities generally goes down when interest rates rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. Changes in interest rates can be sudden and unpredictable and may expose the markets to significant volatility, which also may affect the liquidity of the portfolio's investments and detract from portfolio performance. A variety of factors can impact interest rates, including central bank monetary policies and inflation rates. A general rise in interest rates may cause investors to sell fixed-income securities on a large scale, which could adversely affect the price and liquidity of fixed-income securities generally and could also result in increased redemptions from the portfolio. Increased redemptions could cause the portfolio to sell securities at inopportune times or depressed prices and result in further losses. Inflation and interest rates have been volatile and may increase in the future. Interest rate increases in the future may cause the value of fixed-income securities to decrease and, conversely, interest rate reductions may cause the value of fixed-income securities to increase.

**Index Tracking –** While certain underlying portfolios may seek to track the performance of an index (i.e., achieve a high degree of correlation with the applicable index), the returns of any underlying portfolios that seek to track an index may not match the returns of the applicable index.

**Management** – The value of your investment may go down if the Investment Manager's judgments and decisions are incorrect or otherwise do not produce the desired results, or if the investment strategy does not work as intended. You may also suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, investment techniques applied, or the analyses employed or relied on, by the Investment Manager, if such tools, resources, information or data are used incorrectly or otherwise do not work as intended, or if the Investment Manager's investment style is out of favor or otherwise fails to produce the desired results. Any of these things could cause the portfolio to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

**Active Trading** – The portfolio may engage in active trading of its portfolio. Active trading will increase transaction costs and could detract from performance. Active trading may be more pronounced during periods of market volatility.

**Allocation Conflicts** – The Investment Manager is subject to conflicts of interest in the selection and allocation of the portfolio's assets among underlying portfolios. For example, the Investment Manager has an incentive to select an underlying Transamerica fund over an unaffiliated fund because it receives more revenue, even if the unaffiliated fund has better investment performance or lower total expenses. The Investment Manager also has an incentive to allocate the portfolio's assets to those underlying portfolios paying the highest net management fees to the Investment Manager, to those which are sub-advised by an affiliate of the Investment Manager, and/or to subscale underlying portfolios to reduce amounts waived and/or reimbursed by the Investment Manager to maintain applicable expense caps.

**Asset Class Variation** – The underlying portfolios invest principally in the securities constituting their asset class (i.e., equity or fixed-income) or underlying index components. However, an underlying portfolio may vary the percentage of its assets in these securities (subject to any applicable regulatory requirements). Depending upon the percentage of securities in a particular asset class held by the underlying portfolios at any given time, and the percentage of the portfolio's assets invested in various underlying portfolios, the portfolio's actual exposure to the securities in a particular asset class may vary substantially from its target allocation for that asset class, and this in turn may adversely affect the portfolio's performance.

**Counterparty** – The portfolio could lose money if the counterparties to derivatives, repurchase agreements and/or other financial contracts entered into for the portfolio do not fulfill their contractual obligations. In addition, the portfolio may incur costs and may be hindered or delayed in enforcing its rights against a counterparty. These risks may be greater to the extent the portfolio has more contractual exposure to a counterparty.

**Credit** – If an issuer or other obligor (such as a party providing insurance or other credit enhancement) of a security held by the portfolio or a counterparty to a financial contract with the portfolio is unable or unwilling to meet its financial obligations, or is downgraded or perceived to be less creditworthy (whether by market participants, ratings agencies, pricing services or otherwise), or if the value of any underlying assets declines, the value of your investment will typically decline. A decline may be rapid and/or significant, particularly in certain market environments. In addition, the portfolio may incur costs and may be hindered or delayed in enforcing its rights against an issuer, obligor or counterparty.

**Currency** – The value of a portfolio's investments in securities denominated in foreign currencies increases or decreases as the rates of exchange between those currencies and the U.S. dollar change. U.S. dollar-denominated securities of foreign issuers may also be affected by currency risk. Currency exchange rates can be volatile and may fluctuate significantly over short periods of time. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. A portfolio may be unable or may choose not to hedge its foreign currency exposure or any hedge may not be effective.

------

**Cybersecurity** – Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to portfolio assets, portfolio or shareholder data (including private shareholder information), or proprietary information, cause the portfolio or its service providers (including, but not limited to, the portfolio's investment manager, any sub-adviser(s), transfer agent, distributor, custodian, fund accounting agent and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality, or prevent portfolio investors from purchasing, redeeming or exchanging shares, receiving distributions or receiving timely information regarding the portfolio or their investment in the portfolio. Cybersecurity incidents may render records of portfolio assets and transactions, shareholder ownership of portfolio shares, and other data integral to the functioning of the portfolio inaccessible, inaccurate or incomplete. The use of artificial intelligence and machine learning could exacerbate these risks. Cybersecurity incidents may result in financial losses to the portfolio and its shareholders, and substantial costs may be incurred in order to prevent or mitigate any future cybersecurity incidents.

**Derivatives** – The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Risks of derivatives include leverage risk, liquidity risk, interest rate risk, valuation risk, market risk, counterparty risk and credit risk. Use of derivatives can increase portfolio losses, increase costs, reduce opportunities for gains, increase portfolio volatility, and not produce the result intended. Certain derivatives have the potential for unlimited loss, regardless of the size of the initial investment. Even a small investment in derivatives can have a disproportionate impact on the portfolio. Derivatives may be difficult or impossible to sell, unwind or value, and the counterparty (including, if applicable, the portfolio's clearing broker, the derivatives exchange or the clearinghouse) may default on its obligations to the portfolio. In certain cases, the portfolio may incur costs and may be hindered or delayed in enforcing its rights against or closing out derivatives instruments with a counterparty, which may result in additional losses. Derivatives are also generally subject to the risks applicable to the assets, rates, indices or other indicators underlying the derivative, including market risk, credit risk, liquidity risk, management risk and valuation risk. Also, suitable derivative transactions may not be available in all circumstances or at reasonable prices. The value of a derivative may fluctuate more or less than, or otherwise not correlate well with, the underlying assets, rates, indices or other indicators to which it relates. Using derivatives also subjects the portfolio to certain operational and legal risks. The portfolio may segregate cash or other liquid assets to cover the funding of its obligations under derivatives contracts or make margin payments when it takes positions in derivatives involving obligations to third parties. Rule 18f-4 under the 1940 Act provides a comprehensive regulatory framework for the use of derivatives by funds and imposes requirements and restrictions on portfolios using derivatives. Rule 18f-4 could have an adverse impact on the portfolio's performance and its ability to implement its investment strategies and may increase costs related to the portfolio's use of derivatives. The rule may affect the availability, liquidity or performance of derivatives, and may not effectively limit the risk of loss from derivatives.

**Extension** – When interest rates rise, payments of fixed-income securities, including asset- and mortgage-backed securities, may occur more slowly than anticipated, causing their market prices to decline.

**Focused Investing –** To the extent the portfolio invests a significant portion of its assets in a limited number of countries, regions, sectors, industries or market segments, in a limited number of issuers, or in issuers in related businesses or that are subject to related operating risks, the portfolio will be more susceptible to negative events affecting those countries, regions, sectors, industries, segments or issuers, and the value of its shares may be more volatile than if it invested more widely.

**Industry Concentration** – Certain underlying portfolios may concentrate their investments in issuers of one or more particular industries. Concentration in a particular industry subjects an underlying portfolio to the risks associated with that industry. As a result, an underlying portfolio may be subject to greater price volatility and risk of loss as a result of adverse economic, business or other developments affecting that industry than underlying portfolios investing in a broader range of industries.

**Inflation –** The value of assets or income from investment may be worth less in the future as inflation decreases the value of money. As inflation increases, the real value of the portfolio's assets can decline as can the value of the portfolio's distributions.

**Large Capitalization Companies –** The portfolio's investments in larger, more established companies may underperform other segments of the market because they may be less responsive to competitive challenges and opportunities and unable to attain high growth rates during periods of economic expansion.

**Large Shareholder –** A significant portion of the portfolio's shares may be owned by one or more investment vehicles or institutional investors. Transactions by these large shareholders may be disruptive to the management of the portfolio. For example, the portfolio may experience large redemptions and could be required to sell securities at a time when it may not otherwise desire to do so. Such transactions may increase the portfolio's brokerage and/or other transaction costs. In addition, sizeable redemptions could cause the portfolio's total expenses to increase.

**Leveraging** – To the extent that the portfolio borrows or uses derivatives or other investments, such as ETFs, that have embedded leverage, your investment may be subject to heightened volatility, risk of loss and costs. Other risks also will be compounded because leverage generally magnifies the effect of a change in the value of an asset and creates a risk of loss of value on a larger pool of assets than the portfolio would otherwise have. Use of leverage may result in the loss of a substantial amount, and possibly all, of the portfolio's assets. The portfolio also may have to sell assets at inopportune times to satisfy its obligations.

**Liquidity** – The portfolio may make investments that are illiquid or that become illiquid after purchase. Illiquid investments can be difficult to value, may trade at a discount from comparable, more liquid investments, and may be subject to wide fluctuations in value. Liquidity risk may be magnified in rising interest rate or volatile environments. If the portfolio is forced to sell an illiquid investment to meet redemption requests or other cash needs, the portfolio may be forced to sell at a substantial loss or may not be able to sell at all. Liquidity of particular investments, or even entire asset classes, including U.S. Treasury securities, can deteriorate

------

rapidly, particularly during times of market turmoil, and those investments may be difficult or impossible for the portfolio to sell. This may prevent the portfolio from limiting losses.

**Mortgage-Related and Asset-Backed Securities –** The value of mortgage-related and asset-backed securities will be influenced by factors affecting the housing market and the assets underlying such securities. As a result, during periods of declining asset values, difficult or frozen credit markets, swings in interest rates, or deteriorating economic conditions, mortgage-related and asset-backed securities may decline in value, face valuation difficulties, become more volatile and/or become illiquid, which could negatively impact the portfolio. Mortgage-backed securities represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Asset-backed securities represent participations in, or are secured by and payable from, assets such as installment sales or loan contracts, leases, credit card receivables and other categories of receivables. The value of mortgage-backed and asset-backed securities may be affected by changes in credit quality or value of the mortgage loans or other assets that support the securities. Mortgage-backed and asset-backed securities are subject to prepayment or call and extension risks. Some of these securities may receive little or no collateral protection from the underlying assets. Privately issued mortgage-backed and asset-backed securities are not traded on an exchange and may have a limited market. Without an active trading market, these securities may be particularly difficult to value given the complexities in valuing the underlying collateral. Unlike mortgage-related securities issued or guaranteed by the U.S. government or its agencies and instrumentalities, mortgage-related securities issued by private issuers do not have a government or government-sponsored entity guarantee (but may have other credit enhancement), and may, and frequently do, have less favorable collateral, credit risk or other characteristics. Privately issued mortgage-related securities are also not subject to the same underwriting requirements for the underlying mortgages that are applicable to those mortgage-related securities that have a government or government-sponsored entity guarantee.

**Passive Investment –** Because the sub-adviser of an underlying portfolio seeking to track an index does not select individual companies in the index that the underlying portfolio tracks, the underlying portfolio may hold securities of companies that present risks that an investment adviser researching individual securities might seek to avoid.

**Prepayment or Call** – Many issuers have a right to prepay their fixed-income securities. If this happens, the portfolio will not benefit from the rise in the market price of the securities that normally accompanies a decline in interest rates and may be forced to reinvest the prepayment proceeds in securities with lower yields.

**Small and Medium Capitalization Companies –** The portfolio will be exposed to additional risks as a result of its investments in the securities of small or medium capitalization companies. Small or medium capitalization companies may be more at risk than large capitalization companies because, among other things, they may have limited product lines, operating history, market or financial resources, or because they may depend on a limited management group. Securities of small and medium capitalization companies may be more volatile than and may underperform large

capitalization companies, may have limited liquidity, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

**Structure Conflicts** – Transamerica Asset Management, Inc. ("TAM"), the portfolio's investment manager, has established an investment program whereby a substantial portion of the portfolio's assets are invested in underlying Transamerica funds. TAM does not consider unaffiliated funds as underlying investment options for these assets, even if unaffiliated funds have better investment performance or lower total expenses.

**Valuation** – Certain investments may be more difficult to value than other types of investments. The sales price the portfolio could receive for any particular portfolio investment may differ from the portfolio's valuation of the investment, particularly for securities that trade in thin or volatile markets, that are priced based upon valuations provided by third party pricing services, or that are valued using a fair value methodology. These differences may increase significantly and affect portfolio investments more broadly during periods of market volatility. Investors who purchase or redeem portfolio shares on days when the portfolio is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the portfolio had not fair-valued securities or had used a different valuation methodology. The portfolio's ability to value its investments may also be impacted by technological issues and/or errors by pricing services or other third party service providers. Fair value pricing involves subjective judgment, which may prove to be incorrect.

**Performance:** The bar chart and the table below provide some indication of the risks of investing in the portfolio. The bar chart shows how the portfolio's performance has varied from year to year. The first index in the table shows how the portfolio's average annual total returns for different periods compare to the returns of a broad measure of market performance. One or more secondary indices that the manager believes more closely reflect the market sectors and/or types of investments in which the portfolio invests also are used to measure the portfolio's performance.

The performance calculations do not reflect any charges that are, or may be, imposed under your variable life insurance policy or variable annuity contract. If such charges were reflected, performance would be lower.

Absent any applicable fee waivers and/or expense limitations, performance would be lower.

As with all mutual funds, past performance is not a prediction of future results. Updated performance information is available on our website at https://www.transamerica.com/annuities-performance-center or by calling 1-800-851-9777.

**Purchase and Sale of Portfolio Shares:** Shares of the portfolio may only be purchased or redeemed through variable life insurance policies and variable annuity contracts offered by the separate accounts of participating life insurance companies. Please refer to the corresponding prospectus of the policy or annuity contract that you have chosen for more information about the terms of the offering.

The portfolio does not have any initial or subsequent investment minimums. However, your insurance company may impose investment minimums.

**Tax Information:** Distributions made by the portfolio to an insurance company separate account, and exchanges and redemptions of portfolio shares made by the separate account, ordinarily do not cause the owners of insurance policies and annuity contracts invested in the separate account to recognize income or gain for federal income tax purposes. Please refer to the corresponding

prospectus of the policy or annuity contract that you have chosen for more information regarding the tax consequences of your investment.

**Payments to Broker-Dealers and Other Financial Intermediaries:** The portfolio is generally only available as an underlying investment option for separate accounts of Transamerica life insurance companies to fund benefits under variable life insurance policies and variable annuity contracts. The portfolio and/or its affiliates may make payments to a Transamerica insurance company (or its affiliates) and to broker-dealers and other financial intermediaries for the sale of variable contracts (and thus, indirectly, the portfolio's shares) and related services. These payments may create a conflict of interest by influencing the Transamerica insurance company or other intermediary to recommend the variable contracts that invest in the portfolio. Ask your salesperson or visit your financial intermediary's website for more information.
