The notes issued in connection with the 2019‑1 CLO Transaction (the “2019‑1 Notes”) are secured by a diversified portfolio of the Co-Issuers consisting primarily of middle market loans, the majority of which are senior secured loans (the “2019‑1 Portfolio”). The Co-Issuers also issued Class A‑1L Loans (the “Loans” and, together with the 2019‑1 Notes, the “2019‑1 Debt”). The Loans are also secured by the 2019‑1 Portfolio. At the 2019‑1 Portfolio closing date, the 2019‑1 Portfolio was comprised of assets transferred from the Company and its consolidated subsidiaries. All transfers were eliminated in consolidation and there were no realized gains or losses recognized in the 2019‑1 CLO Transaction.

The Company retained $32.5 million of the Class B-R Notes and $25.0 million of the Class C-R Notes. The retained notes by the Company are eliminated in consolidation. The transaction resulted in a realized loss on the extinguishment of debt of $2.3 million from the acceleration of unamortized debt issuance costs.

The Company has agreed to hold on an ongoing basis the membership interests with an aggregate dollar purchase price at least equal to 5% of the aggregate amount of all obligations issued by the 2019‑1 Co-Issuers for so long as the 2019‑1 Debt remains outstanding.

The 2019‑1 Issuer pays ongoing administrative expenses to the trustee, independent accountants, legal counsel, rating agencies and independent managers in connection with developing and maintaining reports, and providing required services in connection with the administration of the 2019‑1 Issuer.

As of March 31, 2026, there were 52 first lien senior secured loans with a total fair value of approximately $395.7 million and cash of $11.7 million securing the 2019-1 Debt.

The creditors of the 2019-1 Co-Issuers have received security interests in such assets and such assets are not intended to be available to the creditors of the Company (or an affiliate of the Company).
