The following table presents quantitative information about the significant unobservable inputs of the Company’s Level 3 financial instruments.

(1)Weighted averages are calculated based on fair value of investments.

The significant unobservable input used in the yield analysis is the discount rate based on comparable market yields. The significant unobservable input used for market quotations are broker quoted prices provided by independent pricing services. The significant unobservable input used under the market approach is the Performance Multiple. Significant increases in discount rates would result in a significantly lower fair value measurement. Significant decreases in quoted prices or Performance Multiples would result in a significantly lower fair value measurement.

Financial Instruments Not Carried at Fair Value

Debt

The fair value of the Company’s SPV Financing Facilities (as defined in Note 6) and Revolving Credit Facility (as defined in Note 6), as of December 31, 2023 and December 31, 2022, approximates their carrying value as the credit facilities have variable interest based on selected short term rates. These financial instruments would be categorized as Level 3 within the hierarchy.

The following table presents the fair value measurements of the Company's Unsecured Notes (as defined in Note 6) had they been accounted for at fair value. These financial instruments would be categorized as Level 3 as of December 31, 2023 and as Level 2 as of December 31, 2022 within the hierarchy.
