[1] | CLO Notes Payable have maturity dates ranging from June 2025 to January 2037 and have an effective interest rate of 8.25% as of March 31, 2024. A portion of the borrowing outstanding is comprised of subordinated notes which do not have contractual interest rates but instead pay distributions from the excess cash flows of the CLO vehicles.
[2] | Fair value is determined by broker quote and these notes would be classified as Level II within the fair value hierarchy.
[3] | The Secured Borrowing, Due 10/27/2033 has an interest rate of 7.64% and the Secured Borrowing, Due 1/29/2035 has an interest rate of 7.64%. Principal on the Secured Borrowings will be paid over the term with repayment amounts dependent on the performance of the underlying assets securing each borrowing. Repayment amounts from the underlying assets are restricted to solely satisfy the Secured Borrowings obligations. As of March 31, 2024, the fair value of the assets securing both Secured Borrowings equaled $48.5 million.
