Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	The accompanying unaudited Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”) for interim financial information, and with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).
Principles of Consolidation	These unaudited Condensed Consolidated Financial Statements do not include all disclosures associated with the Company’s Consolidated Annual Financial Statements included in its 2024 Annual Report on Form 10-K and, accordingly, should be read in conjunction with the referenced annual report. In the opinion of management, the Condensed Consolidated Financial Statements reflect all adjustments considered necessary for a fair presentation. Adjustments which are not considered normal or recurring in nature have been disclosed within Note 3 - Acquisition, cyber incident and other, net to these Condensed Consolidated Financial Statements. The accompanying Condensed Consolidated Financial Statements also include the accounts of the Company and its wholly owned subsidiaries where the Company exerts control. Intercompany balances and transactions have been eliminated. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for the full year. Investments in which the Company does not have control, and is not the primary beneficiary of a Variable Interest Entity (“VIE”), but where the Company exercises significant influence over the operating and financial policies of the investee, are accounted for using the equity method of accounting.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of (1) assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements and (2) revenues and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications	Reclassifications The Condensed Consolidated Statements of Cash Flows includes various reclassifications, all within Cash Provided by Operating Activities, to conform current and prior period presentation. The Company reclassified impairment charges on certain real estate assets recognized during the three and nine months ended September 30, 2024 from “Other, net” to “Impairment of long-lived assets” on the Condensed Consolidated Statements of Operations to conform current and prior period presentation.
Foreign Currency Related Transactions	Foreign Currency Related Transactions Exchange rate adjustments resulting from foreign currency transactions are recognized in “Net loss” in the Condensed Consolidated Statements of Operations, whereas effects resulting from the translation of financial statements are recognized in “Unrealized net loss on foreign currency” in the Condensed Consolidated Statements of Comprehensive Loss. Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. dollars are translated into U.S. dollars using period-end exchange rates and income statement accounts are translated at weighted average exchange rates.
Recent Rules And Accounting Pronouncements	Recent Rules and Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), which is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in ASU 2023-09 provide for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. ASU 2023-09 is effective for the Company prospectively for all annual periods beginning after December 15, 2024. The Company is currently evaluating the impact of this standard on our annual disclosures for the year ending 2025. In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”. This ASU requires an entity to disclose the amounts of employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. It also requires an entity to include certain amounts that are already required to be disclosed under current GAAP in the same disclosure. Additionally, it requires an entity to disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively, and to disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in the ASU are effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. An entity may apply the amendments prospectively for reporting periods after the effective date or retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of this standard on our Consolidated Financial Statements and the related footnote disclosures. In September 2025, the FASB issued ASU 2025-06, Intangibles – Goodwill and Other – Internal-Use Software. This standard eliminates the prescriptive “project stage” model in ASC 350-40, clarifies the threshold for when entities begin capitalizing software development costs, and requires that disclosure requirements under ASC 360, Property, Plant, and Equipment – Overall, also apply to capitalized software costs regardless of presentation. ASU 2025-06 is effective for interim and annual periods beginning after December 15, 2027, with early adoption permitted, and may be applied prospectively, retrospectively, or under a modified transition approach. The Company is currently evaluating the impact of this guidance but does not expect its adoption to have a material effect on the Consolidated Financial Statements or related footnote disclosures. All other new accounting pronouncements that have been issued, but not yet effective are currently being evaluated and at this time are not expected to have a material impact on our financial position or results of operations.

Disclosure of accounting policy for the use of estimates in the preparation of financial statements in conformity with generally accepted accounting principles.
