[1] As of December 31, 2024, included within Level 3 assets of $582,495 is an amount of $246,742 for which the Investment Adviser did not develop the unobservable inputs (examples include single source broker quotations, third party pricing, and prior transactions). The income approach was used in the determination of fair value for $273,336 or 47.2% of Level 3 bank loans, corporate debt, and other debt obligations.
[2] As of September 30, 2025, the income approach was used in the determination of fair value for $304,937 or 93.9% of Level 3 bank loans, corporate debt, and other debt obligations.
[3] The range for an asset category consisting of a single investment, if any, is not meaningful and therefore has been excluded.
[4] Weighted average for an asset category consisting of multiple investments is calculated by weighting the significant unobservable input by the relative fair value of the investment. Weighted average for an asset category consisting of a single investment represents the significant unobservable input used in the fair value of the investment.
