Transamerica Inflation-Protected Securities

The fund is newly organized. The fund acquired the assets and assumed the liabilities of three Transamerica Partners funds, including Transamerica Partners Institutional Inflation-Protected Securities (the “predecessor fund”), on April 21, 2017, and the predecessor fund is 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, 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 reorganization, and has not been restated to reflect the estimated annual operating expenses of Class R4 shares. Please read the prospectus for more information.

Effective at the close of business on June 29, 2018, the fund changed sub-advisers. The fund’s principal investment strategies, principal risks and portfolio managers changed. The fund’s investment objective and benchmark index remained the same.

30-DAY SEC YIELD
The 30-Day SEC Yield is computed in accordance with a standardized method prescribed by rules of the SEC. The 30-Day SEC Yield is computed by dividing the fund's investment income per share earned during a particular 30-day base period by the maximum offering price per share on the last day of the base period, and then annualizing the result. The 30-Day SEC Yield is calculated at each month end and updated within the first ten business days of the following month. Be advised that the 30-Day SEC Yield calculation does not account for return of capital. Please refer to the most recent Annual Report for additional information regarding the composition of distributions. The subsidized 30-Day SEC Yield reflects the reimbursements or waivers of certain expenses. Had fees not been waived and/or expenses reimbursed, the yield would be lower. The unsubsidized 30-Day SEC Yield does not reflect reimbursements or waivers of expense fees.

DISTRIBUTION RATE
The Distribution Rate is calculated by taking the sum of all distributions occurring over the previous twelve calendar months and dividing the result by the fund’s Net Asset Value (NAV) as of the date of the previous month-end. The Distribution Rate represents a 12-month historical distribution and does not represent the total return of the Fund and is not necessarily an indication of future distributions. Distributions may be comprised of ordinary income, capital gains, and/or return of capital of your investment in the fund. Because the Distribution Rate may include a return of capital, it should not be confused with yield or income. Please refer to the most recent Section 19 Notice, if applicable, for additional information regarding the composition of distributions. However, please note that distributions are subject to recharacterization for tax purposes and the final tax treatment of these distributions will be reported to shareholders after the close of each calendar year on Form 1099-DIV. For funds that have been in operation for less than one year, an annualized Distribution Rate is calculated by annualizing the Fund's historical distributions to date and dividing the result by the fund's NAV as of the date of the previous month-end. The annualized Distribution Rate represents an estimated 12-month distribution from the Fund based on the limited distribution history of the Fund to date and does not represent the total return of the Fund and is not necessarily an indication of future distributions. Past performance does not guarantee future results.

FUND PERFORMANCE
*Expense ratios are as-of the most recent prospectus. Contractual arrangements (if applicable) have been made with the fund’s investment manager, Transamerica Asset Management, Inc. (“TAM”), through March 1, 2019.

**Reflects average annual returns. Returns for funds that are less than one year old are not annualized.

The performance data presented here represents past performance; Past performance is not indicative of future results. Current performance may be lower or higher than the performance data quoted. The investment return and principal value will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Performance may not be available for all periods indicated. Net Asset Value (NAV) returns include reinvestment of dividends and capital gains, but do not reflect any sales charges. If a sales charge had been deducted, the results would have been lower. Public Offering Price (POP) returns include reinvestment of dividends and capital gains, and reflect the maximum sales charge.

There are no sales charges for Class R4 shares. Class R shares are available only to eligible retirement plans.

Performance figures reflect any fee waivers and/or expense reimbursements by the Investment Manager. Without such waivers and/or reimbursements, the performance would be lower. Future waivers and/or reimbursements are at the discretion of the Investment Manager.

1 Year returns reflect total return.

RISK MEASURES

Standard Deviation is a statistical measurement that helps to gauge the fund's historical volatility. Historical Beta illustrates a fund’s sensitivity to price movements in relation to a benchmark index. Alpha is a coefficient measuring the portion of a fund’s return arising from specific (non-market) risk. Tracking Error is the difference between the price behavior of a fund and the price behavior of a benchmark. R-Squared is a statistical measure that represents the percentage of a fund’s movements that can be explained by movements in a benchmark index. Sharpe Ratio is a risk-adjusted measure calculated by using standard deviation and excess return to determine reward per unit of risk. Information Ratio is a ratio of portfolio returns above those of a benchmark compared to the volatility of those returns.

MORNINGSTAR FIXED-INCOME STYLE BOX^TM

The Morningstar Style Box reveals a fund's investment style as of the date noted on this report. For fixed-income funds, the vertical axis shows the credit quality of the long bonds owned and the horizontal axis shows interest rate sensitivity as measured by a bond's effective duration.

Morningstar seeks credit rating information from fund companies on a periodic basis (e.g., quarterly). In compiling credit rating information Morningstar accepts credit ratings reported by fund companies that have been issued by all Nationally Recognized Statistical Rating Organizations (NRSROs). For a list of all NRSROs, please visit http://www.sec.gov/divisions/marketreg/ratingagency.htm. Additionally, Morningstar accepts foreign credit ratings from widely recognized or registered rating agencies. If two rating organizations/agencies have rated a security, fund companies are to report the lower rating; if three or more organizations/agencies have rated a security, fund companies are to report the median rating, and in cases where there are more than two organization/agency ratings and a median rating does not exist, fund companies are to use the lower of the two middle ratings. PLEASE NOTE: Morningstar, Inc. is not itself an NRSRO nor does it issue a credit rating on the fund. An NRSRO or rating agency ratings can change from time-to-time.

For credit quality, Morningstar combines the credit rating information provided by the fund companies with an average default rate calculation to come up with a weighted-average credit quality. The weighted-average credit quality is currently a letter that roughly corresponds to the scale used by a leading NRSRO. Bond funds are assigned a style box placement of "low", "medium", or "high" based on their average credit quality. Funds with a low credit quality are those whose weighted-average credit quality is determined to be less than "BBB-"; medium are those less than "AA-", but greater or equal to "BBB-"; and high are those with a weighted-average credit quality of "AA-" or higher. When classifying a bond portfolio, Morningstar first maps the NRSRO credit ratings of the underlying holdings to their respective default rates (as determined by Morningstar's analysis of actual historical default rates). Morningstar then averages these default rates to determine the average default rate for the entire bond fund. Finally, Morningstar maps this average default rate to its corresponding credit rating along a convex curve.

For interest-rate sensitivity, Morningstar obtains from fund companies the average effective duration. Generally, Morningstar classifies a fixed-income fund's interest-rate sensitivity based on the effective duration of the Morningstar Core Bond Index (MCBI), which is currently three years. The classification of Limited will be assigned to those funds whose average effective duration is between 25% to 75% of MCBI's average effective duration; funds whose average effective duration is between 75% to 125% of the MCBI will be classified as Moderate; and those that are at 125% or greater of the average effective duration of the MCBI will be classified as Extensive. For municipal bond funds, Morningstar also obtains from fund companies the average effective duration. In these cases static breakpoints are utilized. These breakpoints are as follows: (i) Limited: 4.5 years or less; (ii) Moderate: more than 4.5 years but less than 7 years; and (iii) Extensive: more than 7 years. In addition, for non-US taxable and non-US domiciled fixed income funds static duration breakpoints are used: (i) Limited: less than or equal to 3.5 years; (ii) Moderate: greater than 3.5 and less than equal to 6 years; (iii) Extensive: greater than 6 years.

U.S. allocations may include U.S. territories and possessions.

The Net Other Assets (Liabilities) category may include, but is not limited to, repurchase agreements, reverse repurchase agreements, security lending collateral, forward foreign currency contracts, and cash collateral.
