(a)

Senior Floating-Rate Loan Interests (“Senior Loans”) in which the Fund invests generally pay interest at rates which are periodically predetermined by reference to a base lending rate plus a premium. These base lending rates are generally (i) the lending rate offered by one or more major European banks, such as the LIBOR, (ii) the SOFR obtained from the U.S. Department of the Treasury’s Office of Financial Research or another major financial institution, (iii) the prime rate offered by one or more United States banks or (iv) the certificate of deposit rate. Certain Senior Loans are subject to a LIBOR or SOFR floor that establishes a minimum LIBOR or SOFR rate. When a range of rates is disclosed, the Fund holds more than one contract within the same tranche with identical LIBOR or SOFR period, spread and floor, but different LIBOR or SOFR reset dates.

Valuation Inputs

The Fund is subject to fair value accounting standards that define fair value, establish the framework for measuring fair value and provide a three-level hierarchy for fair valuation based upon the inputs to the valuation as of the measurement date. The three levels of the fair value hierarchy are as follows:

• Level 1 – Level 1 inputs are quoted prices in active markets for identical investments.

• Level 2 – Level 2 inputs are observable inputs, either directly or indirectly. (Quoted prices for similar investments, valuations based on interest rates and yield curves, or valuations derived from observable market data.)

• Level 3 – Level 3 inputs are unobservable inputs that may reflect the reporting entity’s own assumptions about the assumptions that market participants would use in pricing the investment.

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