Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Organization and Description of Business Lyft, Inc. (the “Company” or “Lyft”) is incorporated in Delaware with its headquarters in San Francisco, California. The Company operates multimodal transportation networks in the United States and Canada that offer access to a variety of transportation options through the Company’s platform and mobile-based applications. This network enables multiple modes of transportation including the facilitation of peer-to-peer ridesharing by connecting drivers who have a vehicle with riders who need a ride. The Lyft Platform provides a marketplace where drivers can be matched with riders via the Lyft App where the Company operates as a transportation network company (“TNC”). Transportation options through the Company’s platform and mobile-based applications are substantially comprised of its ridesharing marketplace that connects drivers and riders in cities across the United States and in select cities in Canada, Lyft’s network of bikes and scooters (“Light Vehicles"), the Express Drive program, where drivers can enter into short-term rental agreements with Flexdrive or a third party for vehicles that may be used to provide ridesharing services on the Lyft Platform, and Lyft Rentals, a consumer offering for users who want to rent a car for a fixed period of time for personal use, and Lyft Driver Centers and Lyft Auto Care, where drivers and riders can request auto maintenance and collision repair services offered through the Lyft Platform in certain markets. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("GAAP") and the U.S. Securities and Exchange Commission (“SEC”) rules and regulations for interim reporting and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated. The Company uses the U.S. dollar predominantly as the functional currency of its foreign subsidiaries. For foreign subsidiaries where the U.S. dollar is the functional currency, gains and losses from remeasurement of foreign currency balances into U.S. dollars are included on the condensed consolidated statements of operations. For the foreign subsidiary where the local currency is the functional currency, translation adjustments of foreign currency financial statements into U.S. dollars are recorded to a separate component of accumulated other comprehensive loss. The condensed consolidated balance sheet as of December 31, 2021 included herein was derived from the audited financial statements as of that date. The accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary to state fairly the Company’s financial position, results of operations, comprehensive loss, stockholders’ equity, and cash flows for the periods presented, but are not necessarily indicative of the results of operations to be anticipated for any future annual or interim period.
