(7) Asset coverage per unit is the ratio of the carrying value of our total consolidated assets, less all liabilities and indebtedness not represented by senior securities, to the aggregate amount of senior securities representing indebtedness. Asset coverage per unit is expressed in terms of dollar amounts per $1,000 of indebtedness. Asset coverage ratio per unit does not include unfunded commitments. The inclusion of unfunded commitments in the calculation of the asset coverage ratio per unit would not cause the Company to be below the required amount of regulatory coverage.

[2] As of June 30, 2026, the carrying values of the 2026 Notes and the 2028 Notes are presented inclusive of an incremental $(0.0) million and $(0.3) million, each resulting from a hedge accounting relationship. As of December 31, 2025, the carrying value of the 2026 Notes and the 2028 Notes are presented inclusive of an incremental $0.1 million and $0.1 million, respectively, each resulting from a hedge accounting relationship.
[3] Carrying value represents aggregate principal amount outstanding less unamortized debt issuance costs.
