[10] As of December 31, 2023, these investments are categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820") and were valued using significant unobservable inputs.
[11] Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.
[12] Investment has undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.
[13] The interest rate on the principal balance outstanding for most floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the London Interbank Offered Rate ("LIBOR" or "L"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") 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 LIBOR shown above is in U.S. dollars unless otherwise noted. As of December 31, 2023, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.36%, the 90-day SOFR at 5.35%, the 180-day SOFR at 5.18%, the 90-day LIBOR at 5.64%, the PRIME at 8.50%, the SONIA at 5.19%, the 30-day EURIBOR at 3.80%, the 90-day EURIBOR at 3.96% and the 180-day EURIBOR at 3.95%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.
