Subsequent Events	Note 20 - Subsequent Events Acquisition of Careem On January 2, 2020 (“Initial Closing”), the Company completed the previously announced acquisition of substantially all of the assets of Careem Inc. and its subsidiaries (collectively “Careem”) in jurisdictions where the Company received regulatory approval or did not require regulatory approval (“Transferred Assets”). Dubai-based Careem was founded in 2012, provides ridesharing, meal delivery, and payments services to millions of users in cities across the Middle East, North Africa, and Pakistan. This acquisition advances the Company’s strategy of having a leading ridesharing category position in every major region of the world in which the Company operates. The only countries in which Careem operates and regulatory approval has not yet been obtained are Qatar and Morocco (“Deferred Assets”). The Company will continue to seek regulatory approval for the Deferred Assets. While regulatory approval in Pakistan was obtained in February 2020, Pakistan, together with the Deferred Assets, have not yet been transferred to the Company. Pakistan and the Deferred Assets countries will be subject to a delayed closing pending timing of regulatory approval at each of the three, six, and nine month anniversaries of the Initial Closing or at such other time as mutually agreed between the Company and Careem. If regulatory approval is not obtained with respect to any Deferred Assets by the nine month anniversary of the Initial Closing, the Company and Careem may mutually agree to divest any such remaining Deferred Assets. As previously disclosed, the maximum aggregate purchase price is approximately $3.1 billion, consisting of up to approximately $1.7 billion of non-interest bearing unsecured convertible notes and approximately $1.4 billion in cash, subject to certain adjustments and holdbacks equal to 25% of the aggregate purchase price. The notes will be issued in tranches. Each tranche of the unsecured convertible notes is due and payable 90 days once issued. The holders of the unsecured convertible notes may elect to convert the full outstanding principal balance to Class A Common Stock at a conversion price of $55 per share of the Company at any time prior to maturity. The Company is currently evaluating purchase price allocation. It is not practicable to disclose the preliminary purchase price allocation for this acquisition given the short period of time between the acquisition date and the issuance of these consolidated financial statements. Divestiture of Uber Eats India to Zomato On January 21, 2020, the Company entered into a definitive agreement and completed the divestiture of Uber’s food delivery operations in India (“Uber Eats India”) to Zomato Media Private Limited (“Zomato”) in exchange for (i) compulsorily convertible cumulative preference shares of Zomato convertible into ordinary shares representing, when converted, 9.99% of the total voting capital of Zomato and (ii) approximately $35 million in cash for reimbursement by Zomato of goods and services tax. The estimated fair value of the consideration received is $206 million, which includes the investment valued at $171 million and the $35 million of reimbursement of goods and services tax receivable from Zomato. The divestiture of Uber Eats India does not represent a strategic shift that will have a major effect on the Company's operations and financial results, and does therefore not qualify for reporting as a discontinued operation. As of December 31, 2019, the carrying values of the assets and liabilities of the Company’s Uber Eats India operations were not material to be separately reported as held for sale on the consolidated balance sheets.
