* Implied credit spreads, represented in absolute terms, utilized in determining the market value of credit default swap agreements on corporate or sovereign issues as of period end serve as an indicator of the current status of the payment/performance risk and represent the likelihood or risk of default for the credit derivative. The implied credit spread of a particular referenced entity reflects the cost of buying/selling protection and may include upfront payments required to be made to enter into the agreement. Wider credit spreads represent a deterioration of the referenced entity’s credit soundness and a greater likelihood or risk of default or other credit event occurring as defined under the terms of the agreement.

Notes to Portfolio of Investments 

(a)	Represents privately placed and other securities and instruments exempt from Securities and Exchange Commission registration (collectively, private placements), such as Section 4(a)(2) and Rule 144A eligible securities, which are often sold only to qualified institutional buyers. At January 31, 2024, the total value of these securities amounted to $1,461,572,173, which represents 46.81% of total net assets.
(b)	Variable rate security. The interest rate shown was the current rate as of January 31, 2024.
(c)	Represents fair value as determined in good faith under procedures approved by the Board of Trustees. At January 31, 2024, the total value of these securities amounted to $14,561,902, which represents 0.47% of total net assets.
(d)	Valuation based on significant unobservable inputs.
(e)	Variable or floating rate security, the interest rate of which adjusts periodically based on changes in current interest rates and prepayments on the underlying pool of assets. The interest rate shown was the current rate as of January 31, 2024.
(f)	Represents a security purchased on a when-issued basis.
(g)	Non-income producing investment.
(h)	Principal amounts are denominated in United States Dollars unless otherwise noted.
(i)	Represents a variable rate security with a step coupon where the rate adjusts according to a schedule for a series of periods, typically lower for an initial period and then increasing to a higher coupon rate thereafter. The interest rate shown was the current rate as of January 31, 2024.
(j)	Represents a security in default.
(k)	Payment-in-kind security. Interest can be paid by issuing additional par of the security or in cash.
(l)	Principal and interest may not be guaranteed by a governmental entity.
(m)	This security or a portion of this security has been pledged as collateral in connection with derivative contracts.
(n)	Represents a security purchased on a forward commitment basis.
(o)	Represents interest only securities which have the right to receive the monthly interest payments on an underlying pool of mortgage loans.
(p)	The stated interest rate represents the weighted average interest rate at January 31, 2024 of contracts within the senior loan facility. Interest rates on contracts are primarily determined either weekly, monthly or quarterly by reference to the indicated base lending rate and spread and the reset period. Base lending rates may be subject to a floor or minimum rate. The interest rate for senior loans purchased on a when-issued or delayed delivery basis will be determined upon settlement, therefore no interest rate is disclosed. Senior loans often require prepayments from excess cash flows or permit the borrowers to repay at their election. The degree to which borrowers repay cannot be predicted with accuracy. As a result, remaining maturities of senior loans may be less than the stated maturities. Generally, the Fund is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan.
(q)	The rate shown is the seven-day current annualized yield at January 31, 2024.
