Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]      
Business Combination, Achieved in Stages, Description We remeasured our previously held interest in Gulf Island to its fair value of $6,791 and realized a remeasurement gain of $2,818, representing the difference between the carrying value of that interest at September 30, 2025 and its fair value immediately prior to our acquisition of the remaining outstanding shares. Prior to the acquisition of the remaining outstanding shares of Gulf Island, we accounted for our initial investment as a trading security and recorded a gain or loss in each period to adjust the carrying value of the securities to fair value at each period end. The net impact of the change in value of our previously held interest in Gulf Island, inclusive of the final realized gain, was $17 and $2,818 for the three and nine months ended June 30, 2026, and is included in Gain (loss) on marketable securities in the Company's Condensed Consolidated Statements of Comprehensive Income.
