(b)

These securities generally pay interest at rates which are periodically pre-determined by reference to a base lending rate plus a premium. These base lending rates are generally either the lending rate offered by one or more major European banks, such as the “LIBOR” or the prime rate offered by one or more major United States banks, or the certificate of deposit rate. These securities are generally considered to be restricted as the Fund is ordinarily contractually obligated to receive approval from the Agent bank and/or borrower prior to disposition. Remaining maturities of senior loans may be less than the stated maturities shown as a result of contractual or optional payments by the borrower. Such prepayments cannot be predicted with certainty. The interest rate disclosed reflects the rate in effect on May 31, 2021.

(c)	Security exempt from registration under Rule 144A of the Securities Act of 1933. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers.

The Fund utilizes a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The Fund’s policy is to recognize transfers into or out of Level 3 at the end of the reporting period.

A description of the valuation techniques applied to a Fund’s major categories of assets and liabilities measured at fair value on a recurring basis is as follows:

Equity securities are valued at the official closing price (typically last sale) on the exchange on which the securities are primarily traded or, if no closing price is available, at the last bid price and are categorized as Level 1 in the hierarchy. Restricted equity securities and private placements that are illiquid, or are internally fair valued by the Valuation Committee, are generally categorized as Level 3 in the hierarchy.

Certain non-U.S. securities may be fair valued in cases where closing prices are not readily available or are deemed not reflective of readily available market prices. For example, significant events (such as movement in the U.S. securities market, or other regional and local developments) may occur between the time that non-U.S. markets close (where the security is principally traded) and the time that the Fund calculates its net asset value (“NAV”) at the close of regular trading on the New York Stock Exchange (“NYSE”) (generally 4 p.m. Eastern time) that may impact the value of securities traded in these non-U.S. markets. In such cases, the Fund’s fair value non-U.S. securities using an independent pricing service which considers the correlation of the trading patterns of the non-U.S. security to the trading in the U.S. markets for investments such as ADRs, financial futures, Exchange-traded funds (“ETFs”), and certain indexes, as well as prices for similar securities. Such fair valuations are categorized as Level 2 in the hierarchy. Because the frequency of significant events is not predictable, fair valuation of certain non-U.S. common stocks may occur on a frequent basis.

Debt securities, including convertible bonds and restricted securities, are valued based on evaluated quotations received from independent pricing services or from dealers who make markets in such securities. For most bond types, the pricing service utilizes matrix pricing that considers one or more of the following factors: yield or price of bonds of comparable quality, coupon, maturity, current cash flows, type, activity of the underlying equities, and current day trade information, as well as dealer supplied prices. These valuations are generally categorized as Level 2 in the hierarchy. Structured debt instruments, such as mortgage-backed and asset-backed securities may also incorporate collateral analysis and utilize cash flow models for valuation and are generally categorized as Level 2 in the hierarchy. Pricing services do not provide pricing for all securities and therefore indicative bids from dealers are utilized which are based on pricing models used by market makers in the security and are generally categorized as Level 2 in the hierarchy. Debt securities that are internally fair valued by the Valuation Committee are generally categorized as Level 3 in the hierarchy.

Listed derivatives, such as options and futures, that are actively traded are valued at the last posted settlement price from the exchange where they are principally traded and are categorized as Level 1 in the hierarchy. Over-the-counter (“OTC”) derivative contracts, which include forward currency contracts, swaps, swaptions, options and equity linked instruments, are valued based on model prices provided by independent pricing services or from dealer quotes. Depending on the derivative type and the specific terms of the transaction, these models vary and include observable inputs in actively quoted markets including but not limited to: underlying reference entity details, indices, spreads, interest rates, yield curves, dividend and exchange rates. These instruments are generally categorized as Level 2 in the hierarchy. Centrally cleared swaps listed or traded on a bilateral or trade facility platform, such as a registered exchange, are valued at the last posted settlement price determined by the respective exchange. These securities are generally categorized as Level 2 within the hierarchy.

Investments in open-end mutual funds are valued at NAV. Investments in closed-end funds and ETFs are valued as of the close of regular trading on the NYSE each business day. Each is categorized as Level 1 in the hierarchy.

The following is a summary of the inputs used to value the Fund’s net assets by each major security type. The inputs or methodologies used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

A roll forward of fair value measurements using significant unobservable inputs (Level 3) for the year ended May 31, 2021, was as follows:

The table above may include Level 3 investments that are valued by brokers or independent pricing services. The inputs for these investments are not readily available or cannot be reasonably estimated.

The following table presents additional information about valuation techniques and inputs used for investments that are measured at fair value and categorized within Level 3 at May 31, 2021:

The table above does not include Level 3 investments that are valued by brokers or independent pricing services.

The net change in unrealized appreciation/(depreciation) of Level 3 investments held at May 31, 2021 was $(19,992,730).
