Subsequent Events	12. SUBSEQUENT EVENTS On January 29, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Logan Ridge Finance Corporation, a Maryland corporation (“LRFC”), Portman Ridge Merger Sub, Inc., a Maryland corporation and a direct wholly-owned subsidiary of the Company (“Merger Sub”); and solely for the limited purposes set forth therein, Mount Logan Management LLC, a Delaware limited liability company and the external investment adviser to LRFC (“Mount Logan”); and, solely for the limited purposes set forth therein, the Adviser. The Merger Agreement provides that, subject to the conditions set forth therein, (i) at the effective time of the First Merger (the “Effective Time”), Merger Sub will be merged with and into LRFC (the “First Merger”), with LRFC continuing as the surviving company and as a wholly-owned subsidiary of the Company, and (ii) immediately after the Effective Time, LRFC will merge with and into the Company (the “Second Merger” and, together with the First Merger, the “Mergers”), with the Company continuing as the surviving company. Both the Board of Directors of the Company and LRFC’s board of directors, including all of their respective independent directors who are not “interested persons” of either the Company or LRFC or the Adviser or Mount Logan, in each case, on the recommendation of special committees comprised solely of certain independent directors of the Company or LRFC, as applicable (each, a “Special Committee”), have approved, among other things, the Merger Agreement and the transactions contemplated thereby. Consummation of the Mergers is subject to certain closing conditions, including requisite approvals of the Company’s and LRFC’s stockholders. Subject to the terms and conditions of the Merger Agreement, at the Effective Time, each share of LRFC’s common stock issued and outstanding immediately prior to the Effective Time (other than shares owned by the Company or any of its consolidated subsidiaries, including Merger Sub) will be converted into the right to receive 1.500 newly-issued shares of common stock of the Company with cash to be paid (without interest) in lieu of fractional shares. In addition, pursuant to a fee waiver letter executed on January 29, 2025, between the Company and the Adviser, the Adviser has agreed to waive up to $1.5 million of the incentive fees otherwise payable to it by Company over the eight consecutive quarters following the closing of the Mergers, subject to the closing of the Mergers. On March 12, 2025, the Board of Directors of the Company authorized once more a renewed stock repurchase program of up to $10 million (the “2025 Stock Repurchase Program”) for an approximately one-year period, effective March 12, 2025 and terminating on March 31, 2026. The terms and conditions of the 2025 Stock Repurchase Program are substantially similar to the prior Renewed Stock Repurchase Program. The 2025 Stock Repurchase Program may be suspended or discontinued at any time. Subject to these restrictions, we will selectively pursue opportunities to repurchase shares which are accretive to net asset value per share. On March 13, 2025, the Company declared a regular quarterly base distribution of $0.47 per share of common stock and a supplemental cash distribution of $0.07 per share of common stock. The distribution is payable on March 31, 2025 to stockholders of record at the close of business on March 24, 2025. The modification to the dividend policy introduces a stable base distribution, which is anticipated to be sustainable across market cycles, and a quarterly supplemental distribution, which will approximate 50% of net investment income in excess of the quarterly base distribution to account for fluctuations in rates and spreads. The Company has evaluated events and transactions occurring subsequent to December 31, 2024, through the date of issuance, for items that should potentially be recognized or disclosed in these financial statements. Other than as described above, management has determined that there are no other material subsequent events that would require adjustment to, or disclosure in, these consolidated financial statements.
