Investment Valuation

Accounting Standards Codification ASC 820, Fair Value Measurements and Disclosures (ASC 820) defines fair value as the price that would be received to sell an investment in an orderly transaction between two market participants at the measurement date. ASC 820 establishes a fair value hierarchy that distinguishes between market data obtained from independent sources (observable inputs) and the Trust's own market assumptions (unobservable inputs). The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities and the determination of the significance of certain inputs to the fair value measurement requires judgments and considers factors that may be specific to each security. The various inputs that may be used to determine the value of the Trust's investments are summarized in the following fair value hierarchy:

Level 1 - Unadjusted quoted prices in active markets for identical securities.

Level 2 - Other significant observable inputs based on data obtained from various pricing sources (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

Level 3 - Significant unobservable inputs including the Trust's own assumptions used to determine the fair value of investments. Factors considered in making such determinations may include, but are not limited to, information obtained directly from the company or analysts and the analysis of the company's financial statements or other documents.

The following table summarized the Trust's investment as of December 31, 2023, based on the inputs used to value them.

Transfers between hierarchy levels may occur due to market fluctuation, changes in valuation techniques and/or changes in the availability of market data used in the determination of an investment’s valuation. The Trust recognizes transfers between the levels at the end of each period. For the period ended December 31, 2023, there were no transfers among levels 1, 2 and 3.

At December 31, 2023, the reconciliation of assets in which significant unobservable inputs (Level 3) were used in determining fair value, is as follows:

The Financial Accounting Standard Board (FASB) issued guidance that a reporting entity should disclose quantitative information about the unobservable inputs used in the fair value determinations that are categorized in the Level 3 hierarchy. The guidance also required additional disclosure regarding the valuation process used and the sensitivity of the fair value measurements to changes in unobservable inputs and the interrelationships between those unobservable inputs within Level 3. The following table presents a summary of valuation techniques, inputs and quantitative information used in determining the fair value of the Trust’s Level 3 securities as of December 31, 2023:
