Example:

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

The Example assumes that you invest $10,000 in the fund 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 fund’s operating expenses remain the same. Only the 1 year dollar amount shown below reflects TAM's agreement to waive fees and/or reimburse fund expenses. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example - Transamerica Asset Allocation Short Horizon - USD ($)	1 year	3 years	5 years	10 years
Class R	110	348	604	1,338
Class R4	85	271	474	1,058

Portfolio Turnover:

The fund 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 and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the fund’s performance.

During the most recent fiscal year, the portfolio turnover rate for the fund was 26% of the average value of its portfolio.

Principal Investment Strategies:

Transamerica Asset Allocation Short Horizon invests in a combination of Transamerica Funds (“underlying funds”). Transamerica Asset Management, Inc. (the “Investment Manager”) selects the combination and amount of underlying funds to invest in based on the fund’s investment objective.

The following chart shows approximately how much of the assets of the fund are invested in underlying bond, stock and money market funds. These allocations reflect the Investment Manager’s present strategy for asset allocation during normal market conditions, and may be changed at any time without notice to shareholders and without shareholder approval. In the short-term, actual asset allocations may vary due to short-term changes in cash flows caused by purchases and redemptions in the fund.

	Normal Approximate Allocations
	Bond Funds	Stock Funds	Money Market Fund
Short Horizon	89.8%	10%	0.2%

The underlying bond funds normally invest principally in fixed income securities, the underlying stock funds normally invest principally in equity securities, and the underlying money market fund, Transamerica Government Money Market, normally invests principally in U.S. government securities and/or repurchase agreements collateralized by U.S. government securities. In attempting to respond to adverse market or other conditions or to process a large purchase or redemption within the fund, the Investment Manager may allocate assets of the fund without limit to the underlying money market fund.

Each underlying fund has its own investment objective, principal investment strategies and investment risks. The sub-adviser for each underlying fund decides which securities to purchase and sell for that underlying fund. The fund’s ability to achieve its investment objective depends largely on the performance of the underlying funds in which it invests.

The fund may be a significant shareholder in certain underlying funds.

Principal Risks:

Risk is inherent in all investing. Many factors and risks affect the fund's performance, including those described below. The value of your investment in the fund, 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 fund or your investment may not perform as well as other similar investments. The fund, through its investments in underlying funds, is subject to the risks of the underlying funds.

The following is a summary description of principal risks (in alphabetical order after certain key risks) of investing in the fund (either directly or through its investments in underlying funds). Each risk described below may not apply to each underlying fund and an underlying fund may be subject to additional or different risks than those described below. An investment in the fund 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 fund.

Market – The market prices of the fund's securities may go up or down, sometimes rapidly or unpredictably, due to general market conditions, such as overall economic trends or events, government actions or interventions, market disruptions caused by trade disputes or other factors, political factors or adverse investor sentiment. The market prices of securities also may go down due to events or conditions that affect particular sectors, industries or issuers. Adverse market conditions may be prolonged and may not have the same impact on all types of securities. If the market prices of the securities owned by the fund fall, the value of your investment will go down. The fund may experience a substantial or complete loss on any individual security.

Economies and financial markets throughout the world are increasingly interconnected. Economic, financial or political events, trading and tariff arrangements, terrorism, technology and data interruptions, natural disasters and other circumstances in one country or region could be highly disruptive to, and have profound impacts on, global economies or markets. During periods of market disruption, the fund's exposure to the risks described elsewhere in this summary will likely increase. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries directly affected, the value and liquidity of the fund's investments may be negatively affected.

Fixed-Income Securities – Fixed-income securities are subject to risks including 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, 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 fund falls, the value of your investment will go down. The prices of fixed-income securities will generally go down when interest rates rise. Interest rates in the U.S. and certain foreign markets have been low relative to historic levels, so the fund faces a risk that interest rates may rise. A rise in rates tends to have a greater impact on the prices of longer term or duration securities.

Equity Securities – Equity securities represent an ownership interest in an issuer, rank junior in a company’s capital structure and consequently may entail greater risk of loss than debt securities. Equity securities include common and preferred stocks. Stock markets are volatile and the value of equity securities may go up or down sometimes rapidly and unpredictably. Equity securities may have greater price volatility than other asset classes, such as fixed income securities. The value of equity securities fluctuates based on changes in a company’s financial condition, factors affecting a particular industry or industries, and overall market and economic conditions. If the market prices of the equity securities owned by the fund fall, the value of your investment in the fund will decline. If the fund holds equity securities in a company that becomes insolvent, the fund’s interests in the company will rank junior in priority to the interests of debtholders and general creditors of the company, and the fund may lose its entire investment in the company.

Interest Rate – Interest rates in the U.S. and certain foreign markets have been low relative to historic levels. The fund faces a risk that interest rates may rise. The value of fixed income securities generally goes down when interest rates rise, and therefore the value of your investment in the fund may also go down. Debt securities have varying levels of sensitivity to changes in interest rates. A rise in rates tends to have a greater impact on the prices of longer term or duration securities. A significant or rapid rise in rates may result in losses. Changes in interest rates may affect the liquidity and value of the fund’s investments. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions from the fund. If the fund holds variable or floating rate securities, a decrease in interest rates will adversely affect the income received from such securities and the value of the fund’s shares.

Allocation  Conflicts – The Investment Manager is subject to conflicts of interest in allocating the fund’s assets among underlying funds. The Investment Manager and its affiliates will receive more revenue when the Investment Manager selects a Transamerica fund rather than an unaffiliated fund for inclusion in the fund. The Investment Manager has an incentive to allocate the fund’s assets to those underlying funds for which the net management fees payable to the Investment Manager are higher than the fees payable by other underlying funds and/or which are sub-advised by an affiliate of the Investment Manager. The Investment Manager also has an incentive to allocate the fund’s assets to subscale underlying funds to provide scale and reduce amounts waived and/or reimbursed by the Investment Manager to maintain applicable expense caps.

Allocation – The fund’s ability to achieve its investment objectives depends, in large part, upon the Investment Manager’s skill in determining the fund’s asset class allocation and reallocation from time to time, deciding whether and when to tactically overweight or underweight asset classes and selecting a mix of underlying funds. These actions may be unsuccessful in maximizing return and/or avoiding investment losses. 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 fund or other issuer is incorrect. The available underlying funds selected by the Investment Manager may underperform the market or similar funds.

Underlying Funds – Because the fund invests its assets in various underlying funds, its ability to achieve its investment objective depends largely on the performance of the underlying funds in which it invests. Investing in underlying funds subjects the fund to the risks of investing in the underlying securities or assets held by those underlying funds. Each of the underlying funds in which the fund may invest has its own investment risks, and those risks can affect the value of the underlying funds' shares and therefore the value of the fund's investments. There can be no assurance that the investment objective of any underlying fund will be achieved. To the extent that the fund invests more of its assets in one underlying fund than in another, the fund will have greater exposure to the risks of that underlying fund. In addition, the fund will bear a pro rata portion of the operating expenses of the underlying funds in which it invests. See “Appendix A – Asset Allocation Funds” in the prospectus for additional information regarding each underlying fund.

Management – The fund is subject to the risk that the Investment Manager’s judgments and decisions may be incorrect or otherwise may not produce the desired results. The value of your investment may decrease if the Investment Manager’s judgment about the quality, relative yield or value of, or market trends affecting, a particular security or issuer, industry, sector, region or market segment, or about the economy or interest rates, is incorrect. The fund may also suffer losses if there are imperfections, errors or limitations in the quantitative, analytic or other tools, resources, information and data used, or the analyses employed or relied on, by the Investment Manager, if such tools, resources, information or data are used incorrectly, fail to produce the desired results 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. The fund’s investment strategies designed by the Investment Manager may not work as intended. In addition, the fund’s investment strategies or policies may change from time to time. Those changes may not lead to the results intended by the Investment Manager and could have an adverse effect on the value or performance of the fund. Any of these things could cause the fund to lose value or its results to lag relevant benchmarks or other funds with similar objectives.

Active Trading – The fund may purchase and sell securities without regard to the length of time held. Active trading may have a negative impact on performance by increasing transaction costs and may generate greater amounts of net short-term capital gains, which, for shareholders holding shares in taxable accounts, would generally be subject to tax at ordinary income tax rates upon distribution. During periods of market volatility, active trading may be more pronounced.

Asset Class Variation – The underlying funds invest principally in the securities constituting their asset class (i.e., equity or fixed income) or underlying index components. However, an underlying fund 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 funds at any given time, and the percentage of the fund's assets invested in various underlying funds, the fund's actual exposure to the securities in a particular asset class may vary substantially from its target allocation for that asset class.

Convertible Securities – Convertible securities are subject to risks associated with both fixed income and equity securities. When the underlying common stock falls in value, the market price of the convertible security may be more influenced by the security’s yield and fixed income characteristics. When the underlying common stock rises in value, the market price may be more influenced by the equity conversion features. Since the convertible security derives its value from the underlying common stock, the security is also subject to the same types of market and issuer-specific risks that apply to the underlying common stock. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality.

Counterparty – The fund will be subject to the risk that the counterparties to derivatives, repurchase agreements and other financial contracts entered into by the fund or held by special purpose or structured vehicles in which the fund invests will not fulfill their contractual obligations. Adverse changes to counterparties (including derivatives exchanges and clearinghouses) may cause the value of financial contracts to go down. If a counterparty becomes bankrupt or otherwise fails to perform its obligations, the value of your investment in the fund may decline. In addition, the fund may incur costs and may be hindered or delayed in enforcing its rights against 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 fund or a counterparty to a financial contract with the fund is unable or unwilling to meet its financial obligations or is downgraded, or is perceived to be less creditworthy, or if the value of any underlying assets declines, the value of your investment will typically decline. A decline may be significant, particularly in certain market environments. In addition, the fund may incur costs and may be hindered or delayed in enforcing its rights against an issuer, obligor or counterparty. The degree of credit risk of a security or financial contract depends upon, among other things, the financial condition of the issuer and the terms of the security or contract.

Currency – The value of 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, as the revenue earned by issuers of these securities may also be impacted by changes in the issuer’s local currency. Currency conversion costs and currency fluctuations could reduce or eliminate investment gains or add to investment losses. Currency exchange rates can be volatile and may fluctuate significantly over short periods of time, and are affected by factors such as general economic conditions, the actions of the U.S. and foreign governments or central banks, the imposition of currency controls, and speculation. A fund may be unable or may choose not to hedge its foreign currency exposure.

Derivatives – Derivatives involve special risks and costs and may result in losses to the fund. Using derivatives exposes the fund to additional or heightened risks, including leverage risk, liquidity risk, valuation risk, market risk, counterparty risk and credit risk. Their usage can increase fund losses and reduce opportunities for gains when market prices or volatility, interest rates, currencies, or the derivatives themselves, behave in a way not anticipated. Using derivatives may have a leveraging effect, increase fund 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 fund. Derivatives may be difficult to sell, unwind or value, and the counterparty (including, if applicable, the fund’s clearing broker, the derivatives exchange or the clearinghouse) may default on its obligations to the fund. In certain cases, the fund 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 subject to additional risks such as operational risk, including settlement issues, and legal risk, including that underlying documentation is incomplete or ambiguous. 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 and valuation risk. Also, suitable derivative transactions may not be available in all circumstances. 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. The fund may be required to segregate or earmark liquid assets or otherwise cover its obligations under derivatives transactions and may have to liquidate positions before it is desirable in order to meet these segregation and coverage requirements. Use of derivatives may have different tax consequences for the fund than an investment in the underlying assets or indices, and those differences may affect the amount, timing and character of income distributed to shareholders.

Emerging Markets – Investments in the securities of issuers located in or principally doing business in emerging markets are subject to heightened foreign investments risks. Emerging market countries tend to have economic, political and legal systems and regulatory and accounting standards that are less developed, and that can be expected to be less stable. For example, the economies of such countries can be subject to rapid and unpredictable rates of inflation or deflation, and may be based on only a few industries. Emerging market countries may have policies that restrict investment by foreigners or that prevent foreign investors such as the fund from withdrawing their money at will. Emerging market securities are often particularly sensitive to market movements because their market prices tend to reflect speculative expectations. Low trading volumes may result in a lack of liquidity and extreme price volatility. An investment in emerging market securities should be considered speculative.

Extension – When interest rates rise, repayments of fixed income securities, particularly asset- and mortgage-backed securities, may occur more slowly than anticipated, extending the effective duration of these fixed income securities at below market interest rates and causing their market prices to decline more than they would have declined due to the rise in interest rates alone. This may cause the fund's share price to be more volatile or go down.

Focused Investing – To the extent the fund invests 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 fund 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. Local events, such as political upheaval, social unrest, wars and terror attacks, financial troubles, pandemics, epidemics and natural disasters may disrupt a country’s or region’s securities markets. Geographic risk is especially high in emerging and frontier markets.

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 fund’s foreign investments may decline because of factors affecting the particular issuer as well as foreign markets and issuers generally, such as unfavorable or unsuccessful government actions, reduction of government or central bank support, tariffs and trade disruptions, political or financial instability, social unrest or other adverse economic or political developments. Lack of information and weaker legal systems and accounting standards also may affect the value of these securities. Foreign investments may have lower liquidity and be more difficult to value than investments in U.S. issuers.

Growth Stocks – Returns on growth stocks may not move in tandem with returns on other categories of stocks or the market as a whole. Growth stocks typically are particularly sensitive to market movements and may involve larger price swings because their market prices tend to reflect future expectations. When it appears those expectations may not be met, the prices of growth securities typically fall. Growth stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “value” stocks.

High-Yield Debt Securities – High-yield debt securities, commonly referred to as “junk” bonds, are securities that are rated below “investment grade” or, if unrated, determined to be below investment grade by the sub-adviser. Issuers of junk bonds are typically in weaker financial health. Changes in interest rates, the market’s perception of the issuers, the creditworthiness of the issuers and negative perceptions of the junk bond market generally may significantly affect the value of these bonds. Junk bonds are considered speculative, have a higher risk of default, tend to be less liquid and may be more difficult to value than higher grade securities, and they may result in losses for the fund. Junk bonds tend to be volatile and more susceptible to adverse events, credit downgrades and negative sentiments.

Leveraging – The value of your investment may be more volatile to the extent that the fund borrows or uses derivatives or other investments, such as ETFs, that have embedded leverage. 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 fund would otherwise have. The use of leverage is considered to be a speculative investment practice and may result in the loss of a substantial amount, and possibly all, of the fund's assets. The fund also may have to sell assets at inopportune times to satisfy its obligations or meet segregation or coverage requirements.

Liquidity – The fund 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. As a general matter, a reduction in the willingness or ability of dealers and other institutional investors to make markets in fixed income securities may result in even less liquidity in certain markets. If the fund is forced to sell an illiquid investment to meet redemption requests or other cash needs, the fund may be forced to sell at a loss. The fund may not receive its proceeds from the sale of less liquid or illiquid securities for an extended period (for example, several weeks or even longer), and such sale may involve additional costs. Liquidity of particular investments, or even an entire market segment, can deteriorate rapidly, particularly during times of market turmoil, and those investments may be difficult or impossible for the fund to sell. This may prevent the fund 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 fund. Mortgage-backed securities may be issued by private issuers, by government-sponsored entities such as Fannie Mae or Freddie Mac or by agencies of the U.S. government, such as Ginnie Mae. Mortgage-backed securities represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Unlike mortgage-related securities issued or guaranteed by agencies of the U.S. government or government-sponsored entities, 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 underwriting characteristics. 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. The risk of default is generally higher in the case of mortgage-backed investments that include so-called “sub-prime” mortgages. The structure of some of these securities may be complex and there may be less information available than for other types of debt securities. Upon the occurrence of certain triggering events or defaults, the fund may become the holder of underlying assets at a time when those assets may be difficult to sell or may be sold only at a loss.

Prepayment or Call – Many issuers have a right to prepay their fixed income securities. Issuers may be more likely to prepay their securities if interest rates fall. If this happens, the fund will not benefit from the rise in the market price of the securities that normally accompanies a decline in interest rates and will be forced to reinvest prepayment proceeds at a time when yields on securities available in the market are lower than the yield on prepaid securities. The fund may also lose any premium it paid on prepaid securities.

Small and Medium Capitalization Companies – The fund 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. The prices of securities of small and medium capitalization companies generally are more volatile than those of large capitalization companies and are more likely to be adversely affected than large capitalization companies by changes in earnings results and investor expectations or poor economic or market conditions. Securities of small and medium capitalization companies may underperform large capitalization companies, may be harder to sell at times and at prices the portfolio managers believe appropriate and may offer greater potential for losses.

U.S. Government and Agency Obligations – Government agency obligations have different levels of credit support and, therefore, different degrees of credit risk. Securities issued by agencies and instrumentalities of the U.S. government that are supported by the full faith and credit of the U.S. government generally present a lesser degree of credit risk than securities issued by agencies and instrumentalities sponsored by the U.S. government that are supported only by the issuer’s right to borrow from the U.S. Treasury and securities issued by agencies and instrumentalities sponsored by the U.S. government that are supported only by the credit of the issuing agencies. A security backed by the “full faith and credit” of the U.S. government is guaranteed only as to its stated interest rate and face value at maturity, not its current market price.

Valuation – The sales price the fund could receive for any particular portfolio investment may differ from the fund'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 that use matrix or evaluated pricing systems, or that are valued using a fair value methodology. Investors who purchase or redeem fund shares on days when the fund is holding fair-valued securities may receive fewer or more shares or lower or higher redemption proceeds than they would have received if the fund had not fair-valued securities or had used a different valuation methodology. The fund's ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third party service providers.

Value Investing – The prices of securities the sub-adviser to an underlying fund believes are undervalued may not appreciate as anticipated or may go down. The value approach to investing involves the risk that stocks may remain undervalued, undervaluation may become more severe, or perceived undervaluation may actually represent intrinsic value. Value stocks as a group may be out of favor and underperform the overall equity market for a long period of time, for example, while the market favors “growth” stocks.

Performance:

The bar chart and the table below provide some indication of the risks of investing in the fund. The bar chart shows how the fund’s performance has varied from year to year. The table shows how the fund’s average annual total returns for different periods compare to the returns of a broad measure of market performance, as well as comparison to one or more secondary indices.

The fund acquired the assets and assumed the liabilities of two Transamerica Partners asset allocation funds, including Transamerica Institutional Asset Allocation - Short Horizon (the “predecessor fund”), on May 19, 2017, and the predecessor fund was the accounting and performance survivor of the reorganizations. This means that the predecessor fund's financial and performance history became the financial and performance history of the fund. In the reorganization of the predecessor fund, former shareholders of the predecessor fund received Class R4 shares of the fund. The performance of Class R4 shares includes the performance of the predecessor fund prior to the reorganizations, and has not been restated to reflect the annual operating expenses of Class R4 shares.

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

In the “10 Years or Since Inception” column of the table, returns are shown for ten years or since inception of the share class, whichever is less. Index returns are for ten years.

As with all mutual funds, past performance (before and after taxes) is not a prediction of future results. Updated performance information is available on our website at www.transamerica.com/individual/products/mutual-funds/performance/ or by calling 1-888-233-4339.

The after-tax returns are calculated using the historic highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns may depend on the investor’s individual tax situation and may differ from those shown. After-tax returns may not be relevant if the investment is made through a tax-exempt or tax-deferred account, such as a 401(k) plan.

[1] Acquired fund fees and expenses reflect the fund’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 fund’s prospectus.

[2] Contractual arrangements have been made with the fund’s investment manager, Transamerica Asset Management, Inc. (“TAM”), through March 1, 2021 to waive fees and/or reimburse fund expenses to the extent that total annual fund operating expenses exceed 0.60% for Class R shares and 0.35% for Class R4 shares, excluding, as applicable, acquired fund fees and expenses, interest, taxes, brokerage commissions, dividend and interest expenses on securities sold short, extraordinary expenses and other expenses not incurred in the ordinary course of the fund’s business. These arrangements cannot be terminated prior to March 1, 2021 without the Board of Trustees’ consent. TAM is permitted to recapture amounts waived and/or reimbursed to a class during any of the 36 months from the date on which TAM waived fees and/or reimbursed expenses for the class. A class may reimburse TAM only if such reimbursement does not cause, on any particular business day of the fund, the class’ total annual operating expenses (after the reimbursement is taken into account) to exceed the applicable limits described above or any other lower limit then in effect.
