These securities may be sold in certain transactions in reliance on an exemption from registration (normally to qualified institutional buyers). At March 31, 2025, the aggregate value of these securities is $11,234,063 or 10.4% of the Trust's net assets applicable to common shares.
(2) Variable rate security. The stated interest rate represents the rate in effect at March 31, 2025.

(3) Security is valued using significant unobservable inputs and is categorized as Level 3 in the fair value hierarchy.
(4) Non-income producing security.
(5) Security was acquired in connection with a restructuring of a Senior Loan and may be subject to restrictions on resale.
(6) Principal amount is less than $500.
(7) Senior floating-rate loans (Senior Loans) often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay, whether as a contractual requirement or at their election, cannot be predicted with accuracy. As a result, the actual remaining maturity may be substantially less than the stated maturities shown. However, Senior Loans will typically have an expected average life of approximately two to four years. Senior Loans typically have rates of interest which are redetermined periodically by reference to a base lending rate, plus a spread. These base lending rates are primarily the Secured Overnight Financing Rate (“SOFR”) and secondarily, the prime rate offered by one or more major United States banks (the “Prime Rate”). Base lending rates may be subject to a floor, or minimum rate. Rates for SOFR are generally 1 or 3-month tenors and may also be subject to a credit spread adjustment. Senior Loans are generally subject to contractual restrictions that must be satisfied before they can be bought or sold.
(8) Unfunded or partially unfunded loan commitments. The Trust may enter into certain loan agreements all or a portion of which may be unfunded. The Trust is obligated to fund these commitments at the borrower's discretion. The stated interest rate reflects the weighted average of the reference rate and spread for the funded portion, if any, and the commitment fees on the portion of the loan that is unfunded. At March 31, 2025, the total value of unfunded loan commitments is $281,162.
(9) Issuer is in default with respect to interest and/or principal payments or has declared bankruptcy and is non-income producing. For a variable rate security, interest rate has been adjusted to reflect non-accrual status.
(10) This Senior Loan will settle after March 31, 2025, at which time the interest rate will be determined.
(11) The stated interest rate represents the weighted average interest rate at March 31, 2025 of contracts within the senior loan facility. Interest rates on contracts are primarily redetermined either monthly or quarterly by reference to the indicated base lending rate and spread and the reset period.
(12) Fixed-rate loan.
(13) May be deemed to be an affiliated investment company. The rate shown is the annualized seven-day yield as of March 31, 2025.

The Trust is subject to foreign exchange risk in the normal course of pursuing its investment objective. Because the Trust holds foreign currency denominated investments, the value of these investments and related receivables and payables may change due to future changes in foreign currency exchange rates. To hedge against this risk, the Trust enters into forward foreign currency exchange contracts.
At March 31, 2025, the Trust had sufficient cash and/or securities to cover commitments under open derivative contracts.
Affiliated Investments

Fair Value Measurements
Under generally accepted accounting principles for fair value measurements, a three-tier hierarchy to prioritize the assumptions, referred to as inputs, is used in valuation techniques to measure fair value. The three-tier hierarchy of inputs is summarized in the three broad levels listed below.
Level 1 – quoted prices in active markets for identical investments
Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)
Level 3 – significant unobservable inputs (including a fund's own assumptions in determining the fair value of investments)
In cases where the inputs used to measure fair value fall in different levels of the fair value hierarchy, the level disclosed is determined based on the lowest level input that is significant to the fair value measurement in its entirety. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.
At March 31, 2025, the hierarchy of inputs used in valuing the Trust’s investments and open derivative instruments, which are carried at fair value, were as follows:

* None of the unobservable inputs for Level 3 assets, individually or collectively, had a material impact on the Trust.
Level 3 investments at the beginning and/or end of the period in relation to net assets were not significant and accordingly, a reconciliation of Level 3 assets for the fiscal year to date ended March 31, 2025 is not presented.
