NOTES TO SCHEDULE OF INVESTMENTS
Thornburg Limited Term U.S. Government Fund December 31, 2023 (Unaudited)

NOTE 1 – ORGANIZATION
Thornburg Limited Term U.S. Government Fund (the “Fund”) is a diversified series of Thornburg Investment Trust (the “Trust”). The Trust is organized as a Massachusetts business trust under a Declaration of Trust dated June 3, 1987 and is registered as a diversified, open-end management investment company under the Investment Company Act of 1940, as amended (the "1940 Act"). The Fund is currently one of twenty-four separate series of the Trust. Each series is considered to be a separate entity for financial reporting and tax purposes. The Fund currently has seven classes of shares of beneficial interest: Class A, Class C, Class C2, Institutional Class (“Class I”), and Retirement Classes (“Class R3”, “Class R4”, and “Class R5”).
NOTE 2 – SECURITY VALUATION
Valuation of the Fund’s portfolio investment securities is performed by Thornburg Investment Management, Inc., the Trust’s investment advisor (the "Advisor"), which has been designated by the Trustees of the Trust (the "Trustees") as the Fund’s "valuation designee," as that term is defined in rule 2a-5 under the 1940 Act. The Advisor performs this valuation function under the supervision of the Trustees and in accordance with policies and procedures that have been adopted by the Advisor and approved by the Trustees (the “Valuation Policy and Procedures”).
In its capacity as the Fund’s valuation designee, the Advisor makes good faith determinations of the fair value of portfolio securities for which market quotations are not readily available, and otherwise complies with and administers the Valuation Policy and Procedures. The Advisor performs those functions in significant measure through its Valuation and Pricing Committee (the “Committee”), though the Advisor may also obtain the assistance of others, including professional pricing service providers selected and approved by the Committee. In accordance with the Valuation Policy and Procedures, the Committee: assesses and manages the material risks associated with determining the fair value of those Fund investments for which market quotations are not readily available; selects and applies methodologies for determining and calculating such fair values; periodically reviews and tests the appropriateness and accuracy of those methodologies; monitors for circumstances that may necessitate the use of fair value; and approves, monitors, and evaluates pricing services engaged to provide evaluated prices for the Fund’s investments. The Committee provides reports on its activities to the Trustees’ Audit Committee, which is responsible for overseeing the Committee’s and the Advisor’s work in discharging the functions under the Valuation Policy and Procedures.
In those instances when the Committee assists in calculating a fair value for a portfolio investment, the Committee seeks to determine the price that the Fund would reasonably expect to receive upon a sale of the investment in an orderly transaction between market participants on the valuation date. The Committee customarily utilizes quotations from securities broker dealers in calculating valuations, but also may utilize prices obtained from pricing service providers or other methods selected by the Committee. Because fair values calculated by the Committee are estimates, the calculation of a fair value for an investment may differ from the price that would be realized by the Fund upon a sale of the investment, and the difference could be material to the Fund’s financial statements. The Committee’s calculation of a fair value for an investment may also differ from the prices obtained by other persons (including other mutual funds) for the investment.
Valuation of Securities: Investments in U.S. mutual funds are valued at net asset value ("NAV") each business day.
Debt obligations held by the Fund which are not listed or traded on exchanges or for which no reported market exists are ordinarily valued at the valuation obtained from a pricing service provider approved by the Committee.
In any case when a pricing service provider fails to provide a valuation for a debt obligation held by the Fund, the Committee may calculate a fair value for the obligation using alternative methods selected and approved by the Committee. Additionally, in cases when the Committee believes that a valuation obtained from a pricing service provider is stale, does not reflect material factors affecting the valuation of the investment, is significantly different than the value the Fund is likely to obtain if it sought a bid for the investment, or is otherwise unreliable, the Committee may calculate a fair value for the obligation using an alternative method selected and approved by the Committee.
