Transfer of Preferred Equity Investment
On January 19, 2024, we entered into a participation agreement with a separately managed account (the “SMA”), a third-party investor managed by our Manager, to transfer to the SMA $15.0 million of a certain $18.5 million preferred equity investment held by Terra Income Fund 6, LLC, a Delaware limited liability company (“Terra LLC”), our wholly owned subsidiary. Our Manager is managed by, and is a wholly-owned subsidiary of, Terra Capital Partners. Mr. Uppal, our Chief Executive Officer and Chief Investment Officer, controls Mavik, the sole member of Terra Capital Partners. For additional information on our participation agreements, please see the “Participation Agreements” section below.
Cost Sharing and Reimbursement Agreement
We have entered into a cost sharing and reimbursement agreement with Terra LLC effective October 1, 2022, pursuant to which Terra LLC will be responsible for its allocable share of our expenses, including fees paid by us to our Manager based on relative assets under management. These fees are eliminated in consolidation and therefore have no impact on our consolidated financial statements.
Participation Agreements
We have further diversified our exposure to loans and borrowers, and investments and investees, by entering into participation agreements whereby we transferred a portion of certain of our loans and investments on a pari passu basis to related parties, primarily other affiliated funds managed by our Manager or its affiliates, and to a lesser extent, unrelated parties. In connection with the Merger, the obligations under participation agreements with Terra BDC totaling $37.0 million were effectively extinguished. As of December 31, 2023, there was no participation obligation.
The loans and investments that are subject to participation agreements are held in our name, but each of the participant’s rights and obligations, including with respect to interest income and other income (e.g., exit fee, prepayment income) and related fees/expenses (e.g., disposition fees, asset management and asset servicing fees), are based upon their respective pro rata participation interest in such participated investments, as specified in the
