Interest Rate Swaps

In connection with the Unsecured Notes, the Fund has entered into interest rate swaps to more closely align the interest rates of such liabilities with the Fund’s investment portfolio, which consists primarily of floating rate loans. Under the interest rate swaps, the Fund receives a fixed interest rate and pays a floating interest rate of one-month SOFR plus an applicable spread, as disclosed below. The Fund designated these interest rate swaps and the Unsecured Notes as qualifying fair value hedge accounting relationships. As of December 31, 2025 and 2024, the counterparty to all of the Fund’s interest rate swaps was Wells Fargo Bank, N.A. Certain information related to the Fund’s interest rate swaps as of December 31, 2025 is presented below.

(1)In connection with the issuance of the January 2031 Notes, the Fund entered into a forward-starting interest rate swap, with an effective date of July 15, 2026.

See Note 5 for more information on the Unsecured Notes.

As a result of the Fund’s designation of the interest rate swaps as hedging instruments in qualifying fair value hedge accounting relationships, the Fund is required to fair value the hedging instruments and the related hedged items, with the changes in the fair value of each being recorded in interest expense. The net gain related to the fair value hedges was approximately $1,532 for the year ended December 31, 2025 compared to a net loss of approximately $278 for the comparable period in 2024, which is included in “interest and credit facility fees” in the Fund’s consolidated statements of operations. The balance sheet impact of fair valuing the interest rate swaps as of December 31, 2025 and 2024 is presented below:
