Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Liberty Global Ltd. (Liberty Global) is an international provider of broadband internet, video, fixed-line telephony and mobile communications services to residential customers and businesses in Europe. As a result of a series of mergers that were completed on June 7, 2013, Liberty Global plc became the publicly-held parent company of the successors by merger of Liberty Global, Inc. (the predecessor to Liberty Global plc) and Virgin Media Inc. (Virgin Media). On November 23, 2023, Liberty Global plc completed a statutory scheme of arrangement, pursuant to which a new Bermudan company, Liberty Global Ltd., became the sole shareholder of Liberty Global plc and the parent entity of the entire group of Liberty Global companies (the Redomiciliation). The Redomiciliation resulted in the Liberty Global group parent company changing its jurisdiction of incorporation from England and Wales to Bermuda. In these notes, except where context dictates otherwise, the terms “we”, “our”, “our company” and “us” may refer, as the context requires, to Liberty Global (or its predecessors) or collectively to Liberty Global (or its predecessors) and its subsidiaries and any of its joint ventures. Our businesses provide residential and business-to-business (B2B) communications services in (i) Switzerland, which we refer to as “Sunrise”, and Slovakia through certain wholly-owned subsidiaries that we collectively refer to as “Sunrise Holding”, (ii) Belgium and Luxembourg through certain wholly-owned subsidiaries that we collectively refer to as “Telenet” and (iii) Ireland through another wholly-owned subsidiary (VM Ireland). In addition, we own 50% noncontrolling interests in (a) a 50:50 joint venture (the VMO2 JV) with Telefónica SA (Telefónica), which provides residential and B2B communication services in the United Kingdom (U.K.), and (b) a 50:50 joint venture (the VodafoneZiggo JV) with Vodafone Group plc (Vodafone), which provides residential and B2B communication services in the Netherlands. We also own (1) a 50% noncontrolling voting interest in a joint venture (the AtlasEdge JV), which is a leading European Edge data center platform, and (2) a 25% noncontrolling interest in a joint venture (the nexfibre JV), which is constructing a new fiber network in the U.K. outside of the existing footprint of the VMO2 JV. We have announced our intention to spin-off our operations at Sunrise and certain other Liberty Global subsidiaries (together, the Sunrise Entities), which is expected to close during the fourth quarter of 2024. In October 2023, we completed the Telenet Takeover Bid (as defined and described in note 11), pursuant to which we increased our ownership interest in Telenet to 100%. Our unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) and with the instructions to Form 10-Q and Article 10 of Regulation S-X for interim financial information. Accordingly, these financial statements do not include all of the information required by GAAP or Securities and Exchange Commission rules and regulations for complete financial statements. In the opinion of management, these financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the results of operations for the interim periods presented. The results of operations for any interim period are not necessarily indicative of results for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with our 2023 consolidated financial statements and notes thereto included in our 2023 Annual Report on Form 10-K, as amended (our 10-K). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates and assumptions are used in accounting for, among other things, the valuation of acquisition-related assets and liabilities, allowances for uncollectible accounts, certain components of revenue, programming and copyright costs, deferred income taxes and related valuation allowances, loss contingencies, fair value measurements, impairment assessments, capitalization of internal costs associated with construction and installation activities, lease terms, useful lives of long-lived assets, share-based compensation and actuarial liabilities associated with certain benefit plans. Actual results could differ from those estimates. Unless otherwise indicated, ownership percentages and convenience translations into United States (U.S.) dollars are calculated as of March 31, 2024.
