INVESTMENT VALUATION

Transamerica PIMCO Tactical – Growth VP (the “Portfolio”) is a series of the Transamerica Series Trust.

Transamerica Asset Management, Inc. (“TAM”) has been designated as the Portfolio’s valuation designee pursuant to Rule 2a-5 under the Investment Company Act of 1940, as amended, with responsibility for fair valuation subject to oversight by the Portfolio’s Board of Trustees. The net asset value of the Portfolio is computed as of the official close of the New York Stock Exchange (“NYSE”) each day the NYSE is open for business.

TAM utilizes various methods to measure the fair value of its investments on a recurring basis. Generally Accepted Accounting Principles in the United States of America establishes a hierarchy that prioritizes inputs to valuation methods. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The three levels (“Levels”) of inputs of the fair value hierarchy are defined as follows:

Level 1 — Unadjusted quoted prices in active markets for identical securities.

Level 2 — Inputs, other than quoted prices included in Level 1, which are observable, either directly or indirectly. These inputs may include quoted prices for the identical instrument on an inactive market, prices for similar instruments, interest rates, prepayment speeds, credit risk, yield curves, default rates, and similar data.

Level 3 — Unobservable inputs based on the best information available in the circumstances, to the extent observable inputs are not available, which may include TAM’s own assumptions used in determining the fair value of the Portfolio’s investments and derivative instruments.

The inputs used to measure fair value may fall into different Levels of the fair value hierarchy. In such cases, for disclosure purposes, the Level in the fair value hierarchy that is assigned to the fair value measurement of a security is determined based on the lowest Level input that is significant to the fair value measurement in its entirety. Certain investments that are measured at fair value using Net Asset Value (“NAV”) per share, or its equivalent, using the “practical expedient” have not been classified in the fair value Levels. The hierarchy classification of inputs used to value the Portfolio’s investments at March 31, 2024, is disclosed within the Investment Valuation section of the Schedule of Investments.

The availability of observable inputs can vary from security to security and is affected by a wide variety of factors, including, but not limited to, the type of security, whether the security is new and not yet established in the marketplace, the liquidity of markets, and other characteristics particular to the security. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised in determining fair value is generally greatest for instruments categorized in Level 3. Due to the inherent uncertainty of valuation, the determination of values may differ significantly from values that would have been realized had a ready market for investments existed, and the differences could be material.

Fair value measurements: Descriptions of the valuation techniques applied to the Portfolio’s significant categories of assets and liabilities measured at fair value on a recurring basis are as follows:

Asset-backed securities: The fair value of asset-backed securities is estimated based on models that consider the estimated cash flows of each tranche of the entity, establish a benchmark yield, and develop an estimated tranche specific spread to the benchmark yield based on the unique attributes of the tranche. To the extent the inputs are observable and timely, the values would generally be categorized in Level 2 of the fair value hierarchy; otherwise they would be categorized in Level 3.

Corporate debt securities: The fair value of corporate debt securities is estimated using various techniques, which consider recently executed transactions in securities of the issuer or comparable issuers, market price quotations (where observable), bond spreads, fundamental data relating to the issuer, and credit default swap spreads adjusted for any basis difference between cash and derivative instruments. While most corporate debt securities are categorized in Level 2 of the fair value hierarchy, in instances where lower relative weight is placed on transaction prices, quotations, or similar observable inputs, they are categorized in Level 3.

Foreign government obligations: Foreign government obligations are normally valued using a model that incorporates market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers, and reference data. Certain securities are valued by principally using dealer quotations. Foreign government obligations generally are categorized in Level 2 of the fair value hierarchy, or Level 3 if inputs are unobservable.

Loan assignments: Loan assignments are normally valued using an income approach, which projects future cash flows and converts those future cash flows to a present value using a discount rate. The resulting present value reflects the likely fair value of the loan. To the extent the inputs are observable and timely, the values would generally be categorized in Level 2 of the fair value hierarchy; otherwise are categorized in Level 3.

Mortgage-backed securities: The fair value of mortgage-backed securities is estimated based on models that consider issuer type, coupon, cash flows, mortgage prepayment projection tables and adjustable rate mortgage evaluations that incorporate index data, periodic life caps and the next coupon reset date. To the extent the inputs are observable and timely, the values would generally be categorized in Level 2 of the fair value hierarchy; otherwise they are categorized in Level 3.

Municipal government obligations: The fair value of municipal government obligations and variable rate notes is estimated based on models that consider, among other factors, information received from market makers and broker-dealers, current trades, bid-want lists, offerings, market movements, the liquidity of the bond, state of issuance, benchmark yield curves, and bond or note insurance. To the extent the inputs are observable and timely, the values would generally be categorized in Level 2 of the fair value hierarchy; otherwise they are categorized in Level 3.

U.S. government agency obligations: U.S. government agency obligations are comprised of two main categories consisting of agency issued debt and mortgage pass-throughs. Generally, agency issued debt securities are valued in a manner similar to U.S. government obligations. Mortgage pass-throughs include to be announced (“TBA”) securities and mortgage pass-through certificates. Generally, TBA securities and mortgage pass-throughs are valued using dealer quotations. Depending on market activity levels and whether quotations or other observable data are used, these securities are typically categorized in Level 2 of the fair value hierarchy; otherwise they would be categorized in Level 3.

U.S. government obligations: U.S. government obligations are normally valued using a model that incorporates market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers, and reference data. Certain securities are valued by principally using dealer quotations. U.S. government obligations generally are categorized in Level 2 of the fair value hierarchy, or Level 3 if inputs are unobservable.

Short-term notes: The Portfolio normally values short-term government and U.S. government agency securities using a model that incorporates market observable data such as reported sales of similar securities, broker quotes, yields, bids, offers and reference data. Certain securities are valued by principally using dealer quotations. Short-term government and U.S. government agency securities generally are categorized in Level 2 of the fair value hierarchy, or Level 3 if inputs are unobservable.

Securities lending collateral: Securities lending collateral is invested in a money market fund which is valued at the actively traded NAV and no valuation adjustments are applied. Securities lending collateral is categorized in Level 1 of the fair value hierarchy.

Repurchase agreements: Repurchase agreements are valued at cost, which approximates fair value. To the extent the inputs are observable and timely, the values are generally categorized in Level 2 of the fair value hierarchy.

Reverse repurchase agreements: Reverse repurchase agreements are valued at cost, which approximates fair value. To the extent the inputs are observable and timely, the values are generally categorized in Level 2 of the fair value hierarchy.

Derivative instruments: Centrally cleared or listed derivatives that are actively traded are valued based on quoted prices from the exchange and are categorized in Level 1 of the fair value hierarchy. Over-the-counter (“OTC”) derivative contracts include forward, swap, swaption, and option contracts related to interest rates, foreign currencies, credit standing of reference entities, equity prices, or commodity prices. Depending on the product and the terms of the transaction, the fair value of the OTC derivative products are modeled taking into account the counterparties’ creditworthiness and using a series of techniques, including simulation models. Many pricing models do not entail material subjectivity because the methodologies employed do not necessitate significant judgments and the pricing inputs are observed from actively quoted markets, as is the case of interest rate swap and option contracts. The majority of OTC derivative products valued by the Portfolio using pricing models fall into this category and are categorized within Level 2 of the fair value hierarchy or Level 3 if inputs are unobservable.

SUBSEQUENT EVENT

Effective on or about May 1, 2024, the Portfolio will be renamed Transamerica BlackRock iShares Tactical – Growth VP. Also on the effective date, the Portfolio’s principal investment strategies, principal risks, portfolio managers and investment management and sub-advisory fee schedules will change.
