NOTES TO SCHEDULE OF INVESTMENTS
| Thornburg Capital Management Fund | December 31, 2023 (Unaudited) |
NOTE 1 – ORGANIZATION
Thornburg Capital Management 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 offers one class of shares of beneficial interest: Institutional Class (“Class I”).
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: Securities held with a maturity of less than 60 days from trade date and other short-term investments are valued using the amortized cost method unless the Committee determines such method does not represent fair value. The amortized cost method of valuation involves valuing a security at its cost initially and thereafter assuming a constant amortization to maturity of any discount or premium, regardless of the impact of fluctuating interest rates on the market value of the security. This method may result in periods during which value, as determined by amortized cost, is higher or lower than the price the Fund would receive if it sold the security. The market value of securities in the Fund can be expected to vary inversely with changes in prevailing interest rates.
Debt obligations held by the Funds 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 Funds, 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 Funds are 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.
If the market quotation for an investment is expressed in a foreign currency, that market quotation will be converted to U.S. dollars using a foreign exchange quotation from a third-party service at the time of valuation. Foreign investments held by the Funds may be traded on days and at times when the Funds are not open for business. Consequently, the value of the Funds’ investments may be significantly affected on days when shareholders cannot purchase or sell Funds’ shares.
