Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements were prepared using generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and the instructions to Form 10-Q and Regulation S-X. Accordingly, these financial statements do not include all information or notes required by GAAP for annual financial statements and should be read together with the annual financial statements and notes thereto included in the Annual Report. The U.S. dollar is the reporting currency and functional currency for most of our operations except certain of our foreign subsidiaries, which use their local currencies as their functional currency. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using the exchange rates in effect as of the balance sheet date. The effects of these translation adjustments are reflected in accumulated other comprehensive income included in the accompanying unaudited condensed consolidated statements of comprehensive income. The accompanying unaudited condensed consolidated financial statements and related notes present the condensed consolidated financial position of the Company as of September 30, 2026 and December 31, 2025, the results of operations and equity of the Company as of and for the three and nine months ended September 30, 2026 and 2025, and cash flows for the nine months ended September 30, 2026 and 2025. The interim data includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim period. The results of operations for the three and nine months ended September 30, 2026 are not necessarily indicative of the results of operations expected for the entire fiscal year ended December 31, 2026. Further, these estimates and other factors, including those outside the Company’s control, such as the impact of sustained lower commodity prices, could have a significant adverse impact to the Company’s financial condition, results of operations, and cash flows. All intercompany amounts have been eliminated in the presentation of the unaudited condensed consolidated financial statements of the Company. Our chief operating decision maker (“CODM”), the Chief Executive Officer, manages the Company’s business activities as a single operating and reportable segment at the consolidated level. Accordingly, our CODM uses consolidated net income to measure segment profit or loss, allocate resources, and assess performance. Further, the CODM is regularly provided with and utilizes consolidated functional expenses, as presented in the accompanying unaudited condensed consolidated statements of operations, and total assets at the consolidated level, as included in the accompanying unaudited condensed consolidated balance sheets herein, to manage the Company’s operations.
