(a)	Securities are issued in U.S. dollars unless otherwise indicated in the security description.
(b)	Non-income producing security.
(c)	This security is exempt from registration upon resale under Rule 144A of the Securities Act of 1933, as amended (the “1933 Act”) and may be resold in transactions exempt from registration, normally to qualified institutional buyers. This security is not restricted on the foreign exchange where it trades freely without any additional registration. As such, it does not require the additional disclosure required of restricted securities.
(d)	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(e)	This security is fair valued by the Advisor’s Pricing Committee in accordance with procedures approved by the Trust’s Board of Trustees, and in accordance with provisions of the Investment Company Act of 1940 and rules thereunder, as amended. At January 31, 2024, securities noted as such are valued at $252,670 or 0.9% of net assets. Certain of these securities are fair valued using a factor provided by a third-party pricing service due to the change in value between the foreign markets’ close and the New York Stock Exchange close exceeding a certain threshold. On days when this threshold is not exceeded, these securities are typically valued at the last sale price on the exchange on which they are principally traded.
(f)	This security is taxed as a “C” corporation for federal income tax purposes.
(g)	Rate shown reflects yield as of January 31, 2024.

Valuation Inputs

The Funds are subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

The inputs or methodologies used for valuing investments are not necessarily an indication of the risk associated with investing in those investments.
