Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Organization | Note 1. Organization Mount Logan, together with its consolidated subsidiaries (the “Company”) is a diversified alternative asset management and insurance solutions platform. Our mission is to provide our investors access to a diversified and differentiated set of private market investment solutions to address their capital needs. Mount Logan conducts its business primarily in the United States through its two business segments: Asset Management and Insurance Solutions. Our Asset Management segment is conducted by Mount Logan Management LLC (“ML Management”), our SEC-registered investment adviser, manages a significant portion of our Assets Under Management (“AUM”) across our various managed funds supported by permanent and semi-permanent capital bases. Management also directly manages the capital of our wholly-owned insurance company, Ability Insurance Company (“Ability”), for the benefit of policyholders. The Company’s Insurance Solutions segment is conducted by Ability, a Nebraska domiciled insurer, specializes in reinsuring annuity products for the increasing number of individuals seeking to fund retirement needs and represents all of our insurance solutions operations. On September 12, 2025 (the “Closing Date”), the Company completed a business combination pursuant to an Agreement and Plan of Merger, dated as of January 16, 2025 and amended as of July 6, 2025 and August 17, 2025 (the “Merger Agreement”) among the Company (formerly, Yukon New Parent, Inc.), Mount Logan Capital Inc., an insurance company and asset manager organized under the laws of the Province of Ontario (“Legacy Mount Logan”), and 180 Degree Capital Corp. (“TURN”), a New York corporation that was registered as a closed-end investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”), Polar Merger Sub, Inc., a corporation organized under the laws of the State of New York and wholly owned subsidiary of the Company (“TURN Merger Sub”), and Moose Merger Sub, LLC, a limited liability company formed under the laws of the State of Delaware and a wholly owned subsidiary of the Company (“MLC Merger Sub”) wherein (i) TURN Merger Sub. merged with and into TURN, with TURN surviving as a wholly owned subsidiary of the Company, and (ii) MLC Merger Sub merged with and into Legacy Mount Logan, with Legacy Mount Logan surviving as a wholly owned subsidiary of the Company (collectively, the “Business Combination”). In connection with the Business Combination, Legacy Mount Logan was domesticated into a Delaware limited liability company and renamed “Mount Logan Capital Intermediate LLC.” Following the completion of the Business Combination, the Company changed its name to “Mount Logan Capital Inc.” and became a Nasdaq-traded public company. The Business Combination was accounted for as a reverse acquisition, with Legacy Mount Logan identified as the accounting acquirer, but the legal acquiree. Accordingly, our consolidated financial statements present the historical results of Legacy Mount Logan prior to September 12, 2025, and those of the combined company subsequent to that date. Refer to Note 3. Business combinations for more information about the reverse acquisition and the financial reporting impacts. Unless the context otherwise requires, all references to the “Company,” “Mount Logan,” or “we” refer to (i) the Company on or after the Closing Date, and (ii) Legacy Mount Logan prior to the Closing Date.
