The percentage shown for each investment category in the Schedule of Investments is based on net assets.
(1)	Security exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These securities may be sold in certain transactions in reliance on an exemption from registration (normally to qualified institutional buyers). At June 30, 2024, the aggregate value of these securities is $362,265,460 or 48.6% of the Fund's net assets.
(2)	When-issued security.

(3)	Variable rate security. The stated interest rate represents the rate in effect at June 30, 2024.
(4)	Security converts to variable rate after the indicated fixed-rate coupon period.
(5)	When-issued, variable rate security whose interest rate will be determined after June 30, 2024.
(6)	May be deemed to be an affiliated company.
(7)	Restricted security. Total market value of restricted securities amounts to $980,490, which represents 0.1% of the net assets of the Fund as of June 30, 2024.
(8)	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.
(9)	This Senior Loan will settle after June 30, 2024, at which time the interest rate will be determined.
(10)	May be deemed to be an affiliated investment company. The rate shown is the annualized seven-day yield as of June 30, 2024.
(11)	Security exempt from registration under Section 4(2) of the Securities Act of 1933, as amended. Such securities may be sold in transactions exempt from registration only to dealers in that program or other “accredited investors”. At June 30, 2024, the aggregate value of these securities is $7,971,646 representing 1.1% of the Fund’s net assets.
(12)	Rate shown is the discount rate at date of purchase.

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 June 30, 2024, based on the inputs used to value them:
