⁽¹⁵⁾	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.
⁽¹⁶⁾	Amount is less than 0.05% or (0.05)%, as applicable.
⁽¹⁷⁾	This Senior Loan will settle after September 30, 2024, at which time the interest rate will be determined.
⁽¹⁸⁾	Unfunded or partially unfunded loan commitments. The Fund may enter into certain loan agreements all or a portion of which may be unfunded. 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 September 30, 2024, the total value of unfunded loan commitments is $121,901.

Fair Value Measurements

U.S. generally accepted accounting principles (U.S. GAAP) establishes a disclosure hierarchy that categorizes the inputs to valuation techniques used to value assets and liabilities at measurement date. These inputs are summarized in the three broad levels listed below:

Level 1 - quoted prices in active markets for identical securities

Level 2 - other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risk, etc.)

Level 3 - significant unobservable inputs (including the Fund's own assumptions in determining the fair value of investments)

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

The following table summarizes the market value of the Fund's holdings as of September 30, 2024, based on the inputs used to value them:
