NOTE
1 – ORGANIZATION
Thornburg Small/Mid Cap Core 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-six separate series of the Trust. Each
series is considered to be a separate entity for financial reporting and tax purposes. The Fund currently has six classes of shares of beneficial interest: Class A, Class C, 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: Securities and other portfolio investments which are listed or traded on a United States securities exchange are generally valued at the last reported
sale price on the valuation date or, if there has been no sale of the investment on that date, at the mean between the last reported bid and asked prices for the investment on that date. Portfolio investments reported
by NASDAQ are valued at the official closing price on the valuation date. If an investment is traded on more than one exchange, the investment is considered traded on the exchange that is normally the primary market
for that investment. For securities and other portfolio investments which are primarily listed or traded on an exchange outside the United States, the time for determining the investment’s value in accordance
with the first sentence of this paragraph will be the close of that investment’s primary exchange preceding the Fund’s valuation time.
In any case when a market quotation
is not readily available for a portfolio investment ordinarily valued by market quotation, the Committee calculates a fair value for the investment using methodologies selected and approved by the Committee as
described in the Valuation Policy and Procedures, subject to changes or additions by the Committee. For this purpose, a market quotation is considered to be readily available if it is a quoted price (unadjusted) in
active markets for identical investments that the Fund can access at the measurement date. Pursuant to the Valuation Policy and Procedures, the Committee shall monitor for circumstances that may necessitate the use of
fair valuation methodologies, including circumstances in which a market quotation for an investment is no longer reliable or is otherwise not readily available. For that purpose, a market quotation is not readily
available when the primary market or exchange for the applicable investment is not open for the entire scheduled day of trading. A market quotation may also not be readily available if: (a) developments occurring
after the most recent close of the applicable investment’s primary exchange, but prior to the close of business on any business day; or (b) an unusual event or significant period of time occurring since the
availability of the market quotation, create a serious question concerning the reliability of that market quotation. Additionally, a market quotation will be considered unreliable if it would require adjustment under
GAAP, or where GAAP would require consideration of additional inputs in determining the value of the investment. The Committee customarily obtains valuations in those instances from pricing service providers approved
by the Committee. Such pricing service providers ordinarily calculate valuations using multi-factor models to adjust market prices based upon various inputs, including exchange data, depository receipt prices,
futures, index data, and other data.
