⁽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 $161,037,751 or 12.6% of the Fund's net assets.
⁽²⁾	Weighted average fixed-rate coupon that changes/updates monthly. Rate shown is the rate at June 30, 2024.
⁽³⁾	Step coupon security. Interest rate represents the rate in effect at June 30, 2024.
⁽⁴⁾	When-issued security.
⁽⁵⁾	Variable rate security. The stated interest rate represents the rate in effect at June 30, 2024.
⁽⁶⁾	Inverse floating-rate security whose coupon varies inversely with changes in the interest rate index. The stated interest rate represents the coupon rate in effect at June 30, 2024.
⁽⁷⁾	Non-income producing security.

The aggregate market value of securities on loan at June 30, 2024 was $14,246,921 and the total market value of the collateral received by the Fund was $14,820,327, comprised of cash of $8,559,154 and U.S. government and/or agencies securities of $6,261,173.
⁽⁹⁾	For fair value measurement disclosure purposes, security is categorized as Level 3.

⁽¹⁰⁾	Restricted security. Total market value of restricted securities amounts to $2,488,244, which represents 0.2% of the net assets of the Fund as of June 30, 2024.
⁽¹¹⁾	Amount is less than 0.05% or (0.05)%, as applicable.
⁽¹²⁾	Security exempt from registration under Regulation S of the Securities Act of 1933, as amended, which exempts from registration securities offered and sold outside the United States.

At June 30, 2024, the aggregate value of these securities is $578,730 or less than 0.05% of the Fund's net assets.
⁽¹³⁾	Security converts to variable rate after the indicated fixed-rate coupon period.
⁽¹⁴⁾	Perpetual security with no stated maturity date but may be subject to calls by the issuer.
⁽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⁾	Unfunded or partially unfunded loan commitments. The Fund may enter into certain loan agreements all or a portion of which may be unfunded. The Fund 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 June 30, 2024, the total value of unfunded loan commitments is $38,006.
⁽¹⁷⁾	Build America Bond. Represents taxable municipal obligation issued pursuant to the American Recovery and Reinvestment Act of 2009 or other legislation providing for the issuance of taxable municipal debt on which the issuer receives federal support.

⁽²⁰⁾	May be deemed to be an affiliated investment company. The rate shown is the annualized seven-day yield as of June 30, 2024.
⁽²¹⁾	Represents investment of cash collateral received in connection with securities lending.

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.
