Fair Value Measurements

Fair value is defined as the price that would be received upon selling an investment or transferring a liability in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. A three-tier hierarchy is used to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability. Observable inputs are based on market data obtained from sources independent of the reporting entity. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability. Unobservable inputs are based on the best information available in the circumstances. The following is a summary of the three-tiered hierarchy of valuation input levels.

Level 1  –     Inputs are unadjusted and prices are determined using quoted prices in active markets for identical securities.

Level 2  –     Prices are determined using other significant observable inputs (including quoted prices for similar securities, interest rates, credit spreads, etc.).

Level 3  –     Prices are determined using significant unobservable inputs (including management’s assumptions in determining the fair value of investments).

	For Fund portfolio compliance purposes, the Fund’s industry classifications refer to any one or more of the industry sub-classifications used by one or more widely recognized market indexes or ratings group indexes, and/or as defined by Fund management. This definition may not apply for purposes of this report, which may combine industry sub-classifications into sectors for reporting ease.
(1)	All percentages shown in the Portfolio of Investments are based on net assets applicable to common shares unless otherwise noted.
(2)	Senior loans generally pay interest at rates which are periodically adjusted by reference to a base short-term, floating lending rate (Reference Rate) plus an assigned fixed rate (Spread). These floating lending rates are generally (i) the lending rate referenced by the London Inter-Bank Offered Rate (“LIBOR”), or (ii) the prime rate offered by one or more major United States banks. Senior loans may be considered restricted in that the Fund ordinarily is contractually obligated to receive approval from the agent bank and/or borrower prior to the disposition of a senior loan. The rate shown is the coupon as of the end of the reporting period.
(3)	Senior loans generally are subject to mandatory and/or optional prepayment. Because of these mandatory prepayment conditions and because there may be significant economic incentives for a borrower to prepay, prepayments of senior loans may occur. As a result, the actual remaining maturity of senior loans held may be substantially less than the stated maturities shown.
(4)	For financial reporting purposes, the ratings disclosed are the highest of Standard & Poor’s Group (“Standard & Poor’s”), Moody’s Investors Service, Inc. (“Moody’s”) or Fitch, Inc. (“Fitch”) rating. This treatment of split-rated securities may differ from that used for other purposes, such as for Fund investment policies. Ratings below BBB by Standard & Poor’s, Baa by Moody’s or BBB by Fitch are considered to be below investment grade. Holdings designated N/R are not rated by any of these national rating agencies.
(5)	Defaulted security. A security whose issuer has failed to fully pay principal and/or interest when due, or is under the protection of bankruptcy.
(6)	Investment, or portion of investment, represents an outstanding unfunded senior loan commitment.
(7)	Investment valued at fair value using methods determined in good faith by, or at the discretion of, the Board. For fair value measurement disclosure purposes, investment classified as Level 3.
(8)	For fair value measurement disclosure purposes, investment classified as Level 2.
(9)	Non-income producing; issuer has not declared a dividend within the past twelve months.
(10)	A copy of the most recent financial statements for these investment companies can be obtained directly from the Securities and Exchange Commission on its website at http://www.sec.gov.
(11)	The rate shown is the annualized seven-day subsidized yield as of the end of the reporting period.
(12)	Borrowings as a percentage of Total Investments is 25.0%.
(13)	The Fund segregates 100% of its eligible investments (excluding any investments separately pledged as collateral for specific investments in derivatives, when applicable) in the Portfolio of Investments as collateral for borrowings.
(14)	Term Preferred Shares, net of deferred offering costs as a percentage of Total Investments is 12.0%.
(15)	Other assets less liabilities includes the unrealized appreciation (depreciation) of certain over-the-counter (“OTC”) derivatives as well as the unrealized appreciation (depreciation) of OTC cleared and exchange-traded derivatives, when applicable.
(16)	The Fund entered into the credit default swaps to gain investment exposure to the referenced entity. Selling protection has a similar credit risk position to owning the referenced entity. Buying protection has a similar credit risk position to selling the referenced entity short.
(17)	Effective November 1, 2017, the fixed rate paid by the Fund will increase according to a predetermined schedule as specified in the swap contract. Additionally, this fixed rate increase will continue to occur every six months on specific dates through the swap contract's termination date.
(18)	This interest rate swap has an optional early termination date beginning on November 1, 2018 and monthly thereafter through the termination date as specified in the swap contract.
144A	Investment is exempt from registration under Rule 144A of the Securities Act of 1933, as amended. These investments may only be resold in transactions exempt from registration, which are normally those transactions with qualified institutional buyers.
DD1	Portion of investment purchased on a delayed delivery basis.
LIBOR	London Inter-Bank Offered Rate
N/A	Not applicable
PIK	Payment-in-kind (“PIK”) security. Depending on the terms of the security, income may be received in the form of cash, securities, or a combination of both. The PIK rate shown, where applicable, represents the annualized rate of the last PIK payment made by the issuer as of the end of the reporting period.
TBD	Senior loan purchased on a when-issued or delayed-delivery basis. Certain details associated with this purchase are not known prior to the settlement date of the transaction. In addition, Senior loans typically trade without accrued interest and therefore a coupon rate is not available prior to settlement. At settlement, if still unknown, the borrower or counterparty will provide the Fund with the final coupon rate and maturity date.
WI/DD	Purchased on a when-issued or delayed delivery basis.
