[9] The interest rate on the principal balance outstanding for most floating rate loans is indexed to SOFR, EURIBOR, SONIA, NIBOR and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower’s option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate or the alternate base rate based on each respective credit agreement and the cash interest rate as of period end. All SOFR shown above is in U.S. dollars unless otherwise noted. As of September 30, 2024, the reference rates for the Company’s variable rate loans were the 30-day SOFR at 4.85%, the 90-day SOFR at 4.59%, the 180-day SOFR at 4.25%, the PRIME at 8.00%, the SONIA at 5.50%, the 90-day NIBOR at 4.75%, and the 90-day EURIBOR at 3.54%. Most loans include an interest floor, which generally ranges from 0% to 3.00%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

[25] This investment represents a credit default swap that functions, in substance, like a credit linked note and represents a credit risk transfer for a pool of reference assets owned by a bank. The Company fully funded margin up front and in return the Company receives periodic interest payments. The Company’s risk of loss is limited to the principal amount disclosed herein. The reference assets are primarily composed of investment grade corporate debt. The Company may be exposed to counterparty risk, which could make it difficult for the Company to collect on obligations, thereby resulting in potentially significant losses. In addition, the Company only has a contractual relationship with the bank, and not with the reference obligors of the reference assets. Accordingly, the Company generally may have no right to directly enforce compliance by the reference obligors with the terms of the reference assets. The Company will not directly benefit from the reference assets and will not have the benefit of the remedies that would normally be available to a holder of such reference assets. In addition, in the event of the insolvency of the counterparty, the Company may be treated as a general creditor of such counterparty, and will not have any claim with respect to the reference assets.
[26] This investment represents a revenue interest financing term loan in which the Company receives periodic interest payments based on a percentage of revenues earned at the respective portfolio company over the life of the loan.
