[1] As of December 31, 2024, included within the fair value of Level 3 assets of $3,431,997 is an amount of $242,458 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 $3,028,320 or 90.0% of Level 3 bank loans, corporate debt, and other debt obligations.
[2] As of September 30, 2025, included within the fair value of Level 3 assets of $3,173,534 is an amount of $290,434 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 $2,745,539 or 87.9% of Level 3 bank loans, corporate debt, and other debt obligations.
[3] The fair value of any one instrument may be determined using multiple valuation techniques. For example, market comparable and discounted cash flows may be used together to determine fair value. Therefore, the Level 3 balance encompasses both of these techniques.
[4] The range for an asset category consisting of a single investment, if any, is not meaningful and therefore has been excluded.
[5] 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.
[6] Enterprise value of portfolio company as a multiple of earnings before interest, taxes, depreciation and amortization (“EBITDA”).
