(a)	This security, sold within the terms of a private placement memorandum, is exempt from registration upon resale under Rule 144A under the Securities Act of 1933, as amended (the “1933 Act”), and may be resold in transactions exempt from registration, normally to qualified institutional buyers. Pursuant to procedures adopted by the Trust’s Board of Trustees, this security has been determined to be liquid by SSI Investment Management LLC (“SSI”), the Fund’s sub-advisor. Although market instability can result in periods of increased overall market illiquidity, liquidity for each security is determined based on security specific factors and assumptions, which require subjective judgment. At July 31, 2021, securities noted as such amounted to $102,628,588 or 30.7% of net assets.
(b)	This security may be resold to qualified foreign investors and foreign institutional buyers under Regulation S of the 1933 Act.
(c)	Zero coupon security.
(d)	Stated maturity represents the mandatory conversion date.
(e)	Perpetual maturity.
(f)	Aggregate cost for financial reporting purposes approximates the aggregate cost for federal income tax purposes. As of July 31, 2021, the aggregate gross unrealized appreciation for all investments in which there was an excess of value over tax cost was $60,556,391 and the aggregate gross unrealized depreciation for all investments in which there was an excess of tax cost over value was $2,746,363. The net unrealized appreciation was $57,810,028.

Valuation Inputs

The Fund is 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.

A summary of the inputs used to value the Fund’s investments as of July 31, 2021 is as follows:
