Description of Business and Summary of Significant Accounting Policies	Note 1 – Description of Business and Summary of Significant Accounting Policies Description of Business Uber Technologies, Inc. (“Uber”, “we,” “our,” or “us”) was incorporated in Delaware in July 2010, and is headquartered in San Francisco, California. Uber is a technology platform that uses a massive network, leading technology, operational excellence and product expertise to power movement from point A to point B. Uber develops and operates proprietary technology applications supporting a variety of offerings on its platform (“platform(s)” or “Platform(s)”). Uber connects consumers (“Rider(s)”) with independent providers of ride services (“Mobility Driver(s)”) for ridesharing services, and connects consumers (“Eater(s)”) with restaurants, grocers and other stores (collectively, “Merchants”) and delivery service providers (“Delivery People”) for meal preparation, grocery and other delivery services. Riders and Eaters are collectively referred to as “end-user(s)” or “consumer(s).” Mobility Drivers and Delivery People are collectively referred to as “Driver(s).” Uber also connects consumers with public transportation networks, e-bikes, e-scooters and other personal mobility options. Uber uses this same network, technology, operational excellence and product expertise to connect shippers with carriers in the freight industry. Uber is also developing technologies that will provide autonomous driving vehicle solutions to consumers, networks of vertical take-off and landing vehicles and new solutions to solve everyday problems. Our technology is used around the world, principally in the United States (“U.S.”) and Canada, Latin America, Europe, the Middle East, Africa, and Asia (excluding China and Southeast Asia). Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2019 included herein was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2019, included in our Annual Report on Form 10-K. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, comprehensive loss, cash flows and the change in equity for the periods presented. There have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 2, 2020 that have had a material impact on our condensed consolidated financial statements and related notes, except for an update reflecting the new accounting standard related to the measurement of credit losses on available-for-sale debt securities and disclosure of our policy related to restructuring and related charges. The evolving nature of the coronavirus disease COVID-19 (“COVID-19”) pandemic and the extent of its impact across industries and geographies, including the duration and spread of the outbreak, continue to be uncertain and cannot be predicted. Therefore, the results of operations for the three and nine months ended September 30, 2020 may not be indicative of the results to be expected for subsequent quarters and the full fiscal year. Basis of Consolidation Our condensed consolidated financial statements include the accounts of Uber Technologies, Inc. and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 14 – Variable Interest Entities (“VIEs”) for further information. Use of Estimates The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, management evaluates estimates, including, but not limited to: the incremental borrowing rate (“IBR”) applied in lease accounting; fair values of investments and other financial instruments (including the measurement of credit or impairment losses); useful lives of amortizable long-lived assets and intangible assets; fair value of acquired intangible assets and related impairment assessments; impairment of goodwill; stock-based compensation; income taxes and non-income tax reserves; certain deferred tax assets and tax liabilities; insurance reserves; and other contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates. We considered the impacts of the COVID-19 pandemic on the assumptions and inputs (including market data) supporting certain of these estimates, assumptions and judgments, in particular, our impairment assessment related to the determination of the fair values of certain investments and equity method investments as well as goodwill and the recoverability of long-lived assets. The level of uncertainties and volatility in the global financial markets and economies resulting from the pandemic as well as the uncertainties related to the impact of the pandemic on us and our investees' operations and financial performance means that these estimates may change in future periods, as new events occur and additional information is obtained. Certain Significant Risks and Uncertainties - COVID-19 In March 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic. COVID-19 has rapidly impacted market and economic conditions globally. In an attempt to limit the spread of the virus, various governmental restrictions have been implemented, including business activities and travel restrictions, and “shelter-at-home” orders, that have had an adverse impact on our business and operations by reducing, in particular, the global demand for Mobility offerings. In light of the evolving nature of COVID-19 and the uncertainty it has produced around the world, it is not possible to predict the COVID-19 pandemic’s cumulative and ultimate impact on our future business operations, results of operations, financial position, liquidity, and cash flows. The extent of the impact of the pandemic on our business and financial results will depend largely on future developments, including the duration of the spread of the outbreak both globally and within the United States, including whether there will be resurgences of COVID-19 in various regions, the impact on capital, foreign currencies exchange and financial markets, governmental or regulatory orders that impact our business and whether the impacts may result in permanent changes to our end-user’ behavior, all of which are highly uncertain and cannot be predicted. Revenue Recognition Mobility During the first quarter of 2020, we began charging end-users a fee for services in certain markets. In these transactions, we enter into a Master Services Agreements (“MSA”) with the end-user to use the platform for a fee. The combination of the MSA and the individual transaction request establishes enforceable rights and obligations for each transaction. We have determined that in these transactions, the end-user is our customer, in addition to the previously disclosed customers, and revenue from these contracts is also recognized under Accounting Standards Codification (“ASC”) 606. In these transactions, in addition to a performance obligation to Drivers, we also have one performance obligation to end-users, which is to connect end-users to Drivers in the marketplace. We recognize revenue when a trip is complete. We continue to present revenue on a net basis for these transactions, as we do not control the service provided by Drivers to end-users. We recognized total revenue of $61 million and $253 million associated with these fees charged to end-users for the three and nine months ended September 30, 2020, respectively. Delivery During the first quarter of 2020, we began charging a direct fee to end-users for delivery services in certain markets. In these transactions, we enter into an MSA with the end-user to use the platform for delivery services for a fee and separately subcontract with Delivery People to provide delivery services to end-users. The combination of the end-user MSA and the individual end-user transaction request establishes enforceable rights and obligations for each transaction. Our contract with end-users creates one performance obligation, which is to provide delivery services to end-users in these markets. We have determined that in these transactions, restaurants and end-users are our customers and revenue from these contracts shall be recognized separately for each under ASC 606. We recognize delivery service revenue associated with our performance obligation over the contract term, which represents our performance over the period of time the delivery is occurring. Our previously disclosed revenue recognition policy for contracts with Merchants remains unchanged. We present revenue on a gross basis for the delivery of meals, as we control the delivery service in these transactions and we are primarily responsible for delivery. Consistent with previous disclosures, we will continue to present revenue on a net basis for the sale of meals. We recognized revenue of $39 million and $77 million for the three and nine months ended September 30, 2020, respectively and cost of revenue, exclusive of depreciation and amortization of $119 million and $269 million for the three and nine months ended September 30, 2020, respectively for these delivery transactions. End-user Discounts and Promotions Any promotions utilized by an end-user in these Mobility and Delivery transactions where the end-user is a customer are accounted for as consideration payable to a customer, and recorded as a reduction of revenue, if we do not receive a distinct good or service or cannot reasonably estimate the fair value of the good or service received. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable represents uncollected fare payments from end-users for completed transactions where (i) the payment method is credit card and includes (a) end-user fare amounts not yet settled with payment service providers, and (b) end-user fare amounts settled by payment service providers but not yet remitted to us, or (ii) completed shipments where we invoice Freight Customers (“Shippers”) and payment has not been received. The timing of settlement of amounts due from these parties varies by region and by product. The portion of the fare receivable to be remitted to Drivers and Merchants is included in accrued and other current liabilities. Refer to Note 8 – Supplemental Financial Statement Information for amounts payable to Drivers and Merchants. Although we pre-authorize forms of payment to mitigate our exposure, we bear the cost of any accounts receivable losses. We record an allowance for doubtful accounts for credit losses for fare and invoiced amounts that may never settle or be collected, as well as for credit card chargebacks including fraudulent credit card transactions. We consider the allowance for doubtful accounts for fare amounts to be direct and incremental costs to revenue earned and, therefore, the costs are included as cost of revenue in the consolidated statements of operations. We estimate the allowance based on historical experience, estimated future payments and geographical trends, which are reviewed periodically and as needed, and amounts are written off when determined to be uncollectable. Allowance for Credit Losses on Available-for-sale Debt Securities We account for credit losses on available-for-sale debt securities in accordance with ASC 326, Financial Instruments - Credit Losses (“ASC 326”). We adopted ASC 326 on January 1, 2020, on a modified retrospective basis. Under ASC 326, at each reporting period, we evaluate our available-for-sale debt securities at the individual security level to determine whether there is a decline in the fair value below its amortized cost basis (an impairment). In circumstances where we intend to sell, or are more likely than not required to sell, the security before it recovers its amortized cost basis, the difference between fair value and amortized cost is recognized as a loss in the consolidated statement of operations, with a corresponding write-down of the security’s amortized cost. In circumstances where neither condition exists, we then evaluate whether a decline is due to credit-related factors. The factors considered in determining whether a credit loss exists can include the extent to which fair value is less than the amortized cost basis, changes in the credit quality of the underlying loan obligors, credit ratings actions, as well as other factors. To determine the portion of a decline in fair value that is credit-related, we compare the present value of the expected cash flows of the security discounted at the security’s effective interest rate to the amortized cost basis of the security. A credit-related impairment is limited to the difference between fair value and amortized cost, and recognized as an allowance for credit loss on the consolidated balance sheet with a corresponding adjustment to net income (loss). Any remaining decline in fair value that is non-credit related is recognized in other comprehensive income (loss), net of tax. Improvements in expected cash flows due to improvements in credit are recognized through reversal of the credit loss and corresponding reduction in the allowance for credit loss. Restructuring and Related Charges Costs associated with management-approved restructuring activities, including reductions in headcount, exiting a market or consolidation of facilities are recognized when they are incurred and may include employee termination benefits, impairment of long-lived assets, impairment of operating lease right-of-use assets, contract termination costs and accelerated lease cost for right-of-use assets that ceased to be used. We record a liability for employee termination benefits either when it is probable that an employee is entitled to them and the amount of the benefits can be reasonably estimated or when management has communicated the termination plan to employees and all of the following conditions have been met: management, having the authority to approve the action, commits to a plan of termination; the plan identifies the number of employees to be terminated, their job classifications and their locations, and the expected completion date; the plan establishes the terms of the benefit arrangement in sufficient detail to enable employees to determine the type and amount of benefits they will receive if they are involuntarily terminated; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We accrue for costs to terminate contracts other than a lease when we terminate the contract in accordance with the contract terms. Costs that will continue to be incurred for the remaining term of a contract that is not a lease, and provide no economic benefits to us are recognized at the cease-use date. Costs associated with lease contracts are accounted for under the leasing accounting guidance or under the long-lived assets accounting guidance. Restructuring and related charges are recognized as an operating expense within the condensed consolidated statement of operations and are classified based on our classification policy for each category of operating expense. Personnel costs are classified based on each employee’s classification, impairment of long-lived assets are recorded within general and administrative expenses, and lease costs, including impairments of right-of-use assets, are classified in the same expense line item where each lease’s rent expense was recognized. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” to require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, reasonable and supportable forecasts. The standard also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASC 326 was subsequently amended by ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” We adopted the standard and related amendments effective January 1, 2020 on a modified retrospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements in ASC 820, “Fair Value Measurement” (“ASC 820”). We adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. We adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In October 2018, the FASB issued ASU 2018-17, “Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest and requires organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety. We adopted the new standard effective January 1, 2020 on a retrospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes certain exceptions for performing intraperiod allocation, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance reduces complexity in certain areas, including franchise taxes that are partially based on income and accounting for tax law changes in interim periods. We early adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued. The standard is effective upon issuance through December 31, 2022 and may be applied at the beginning of the interim period that includes March 12, 2020 or any date thereafter. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which reduces the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue	Note 2 – Revenue The following tables present our revenues disaggregated by offering and geographical region. Revenue by geographical region is based on where the trip or shipment was completed or meal or grocery order delivered. This level of disaggregation takes into consideration how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors. Revenue is presented in the following tables for the three and nine months ended September 30, 2019 and 2020 (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2019 2020 2019 2020 Mobility revenue $ 2,895 $ 1,365 $ 7,689 $ 4,624 Delivery revenue 645 1,451 1,776 3,481 Freight revenue 218 288 512 698 ATG and Other Technology Programs collaboration revenue (1) 17 25 17 75 All Other revenue 38 — 84 35 Total revenue $ 3,813 $ 3,129 $ 10,078 $ 8,913 (1) Refer to Note 15 – Non-Controlling Interests for further information on collaboration revenue.

Mobility revenue also includes immaterial revenue streams such as our Uber for Business (“U4B”), financial partnerships products and Vehicle Solutions. Vehicle Solutions revenue is accounted for as an operating lease as defined under ASC 842. Delivery Revenue We derive revenue for Delivery from Merchants’ and Delivery People’s use of the Delivery platform and related service to facilitate and complete Delivery transactions. Additionally, in certain markets where we are responsible for delivery services, delivery fees charged to end-users are also included in revenue, while payments to Delivery People in exchange for delivery services are recognized in cost of revenue. Freight Revenue Freight revenue consists of revenue from freight transportation services provided to shippers. All Other Revenue Prior to the second quarter of 2020, All Other revenue (formerly our Other Bets segment) consisted primarily of revenue from New Mobility products, including dockless e-bikes, and Platform Incubator group offerings, which are responsible for innovating new services and use cases on our platform to drive long-term growth and cross-platform customer engagement, and other immaterial revenue streams. New Mobility revenue is accounted for as an operating lease as defined under ASC 842. After the JUMP Divestiture during the second quarter of 2020, revenue from New Mobility products, including dockless e-bikes, was no longer material. Refer to Note 17 – Divestitures for further information regarding the JUMP Divestiture. Contract Balances During the second quarter of 2020, we modified a revenue contract originally entered into in 2018. As a result of the modification, the consideration allocated to an unfulfilled performance obligations is no longer material. Our contract assets for performance obligations satisfied prior to payment or contract liabilities for consideration collected prior to satisfying the performance obligations are not material as of December 31, 2019 and September 30, 2020.

Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table presents our financial assets and liabilities measured at fair value on a recurring basis based on the three-tier fair value hierarchy (in millions): As of December 31, 2019 As of September 30, 2020 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Financial Assets Money market funds $ 5,104 $ — $ — $ 5,104 $ 2,355 $ — $ — $ 2,355 Commercial paper — 233 — 233 — 562 — 562 U.S. government and agency securities — 153 — 153 — 458 — 458 Corporate bonds — 199 — 199 — 364 — 364 Non-marketable debt securities — — 2,370 2,370 — — 2,347 2,347 Non-marketable equity securities — — 98 98 — — 53 53 Note receivable from a related party — — — — — — 83 83 Total financial assets $ 5,104 $ 585 $ 2,468 $ 8,157 $ 2,355 $ 1,384 $ 2,483 $ 6,222 During the nine months ended September 30, 2020, we did not make any transfers between the levels of the fair value hierarchy. The following table summarizes the amortized cost and fair value of our debt securities with a stated contractual maturity or redemption date as of September 30, 2020 (in millions): As of September 30, 2020 Amortized Cost Fair Value Within one year $ 1,336 $ 1,338 One year through five years 2,327 2,393 Total $ 3,663 $ 3,731 The following table summarizes the amortized cost, unrealized gains and losses, fair value and, beginning in 2020, allowance for credit loss, of our debt securities at fair value on a recurring basis as of December 31, 2019 and September 30, 2020 (in millions): As of December 31, 2019 As of September 30, 2020 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Amortized Cost Unrealized Gains Unrealized Losses Allowance for Credit Loss Fair Value Commercial paper $ 233 $ — $ — $ 233 $ 562 $ — $ — $ — $ 562 U.S. government and agency securities 153 — — 153 458 — — — 458 Corporate bonds 199 — — 199 362 2 — — 364 Non-marketable debt securities 2,309 61 — 2,370 2,281 66 — — 2,347 Total $ 2,894 $ 61 $ — $ 2,955 $ 3,663 $ 68 $ — $ — $ 3,731 The following table presents information about the allowance for credit losses on debt securities (in millions): Non-marketable Balance as of January 1, 2020 $ — Impact due to adoption of ASU 2016-13 — Credit losses on securities for which credit losses were not previously recorded (173) Decrease to allowance for credit loss previously recorded 173 Balance as of September 30, 2020 $ — We measure our cash equivalents and certain investments at fair value. Level 1 instrument valuations are based on quoted market prices of the identical underlying security. Level 2 instrument valuations are obtained from readily available pricing sources for comparable instruments, identical instruments in less active markets, or models using market observable inputs. Level 3 instrument valuations are valued based on unobservable inputs and other estimation techniques due to the absence of quoted market prices, inherent lack of liquidity and the long-term nature of such financial instruments. Our Level 3 non-marketable debt securities as of December 31, 2019 and September 30, 2020 primarily consist of redeemable preferred stock investments in privately held companies without readily determinable fair values. Depending on the investee’s financing activity in a reporting period, management’s estimate of fair value may be primarily derived from the investee’s financing transactions, such as the issuance of preferred stock to new investors. The price in these transactions generally provides the best indication of the enterprise value of the investee. Additionally, based on the timing, volume, and other characteristics of the transaction, we may supplement this information by using other valuation techniques, including the guideline public company approach. The guideline public company approach relies on publicly available market data of comparable companies and uses comparative valuation multiples of the investee’s revenue (actual and forecasted), and therefore, unobservable data used in this valuation technique primarily consists of short-term revenue projections. Once the fair value of the investee is estimated, an option-pricing model (“OPM”) is employed to allocate value to various classes of securities of the investee, including the class owned by us. The model involves making assumptions around the investees’ time to liquidity and volatility. An increase or decrease in any of the unobservable inputs in isolation, such as the security price in a financing transaction of the investee, could result in a material increase or decrease in our estimate of fair value. Other unobservable inputs, including short-term revenue projections, time to liquidity, and volatility are less sensitive to the valuation in the respective reporting periods, as a result of the primary weighting on the investee’s financing transactions. In the future, depending on the weight of evidence and valuation approaches used, these or other inputs may have a more significant impact on our estimate of fair value. We determine realized gains or losses on the sale of equity and debt securities on a specific identification method. Grab Investment The following table summarizes information about the significant unobservable inputs used in the fair value measurement for our investment in Grab as of December 31, 2019 and September 30, 2020: Fair value method Relative weighting Key unobservable inputs Financing transactions 100% Transaction price per share $6.16 Volatility 54% Estimated time to liquidity 1.8 - 2.5 years During the first quarter of 2020, we determined the fair value of our available-for-sale debt securities in Grab had declined below their amortized cost based on an analysis of the observed valuation declines of Grab’s publicly-traded competitive peer group and representative stock market indices. These observed inputs were considered indicative of changes in the fair value of the Grab securities. Using the analysis, we computed a downward market adjustment of 10% that was applied to the valuation derived from Grab’s latest financing transaction which occurred earlier in the first quarter of 2020 and prior to the announcement of COVID-19 as a global pandemic, impacting global demand for Mobility services. As a result, the carrying value of the investment in Grab was reduced by $230 million; $57 million reduced the previously recognized unrealized gain in other comprehensive income (loss), net of tax, and the remaining $173 million, representing the difference between the fair value and amortized cost of the securities, was recognized as an allowance for credit loss in the condensed consolidated balance sheet and a corresponding credit-related impairment charge recorded to other income (expense), net in the condensed consolidated statement of operations. Due to the significant uncertainty about Grab’s ability to repay the redemption amount of the securities on the redemption date, the amount expected to be collected is considered to be less than the fair value of the securities. Therefore, the entire decline in fair value below amortized cost was considered to reflect a credit-related impairment charge. As of September 30, 2020, the fair value of our Grab investment was determined by referencing an equity financing transaction closed by the investee during the third quarter of 2020. As a result, the fair value of our Grab investment increased by $226 million from June 30, 2020; $160 million was recognized as a reversal of the previously recorded allowance for credit loss in the condensed consolidated balance sheet and a corresponding reversal of the credit-related impairment charge to other income (expense), net in the condensed consolidated statement of operations. The remaining $66 million of unrealized gain was recorded in other comprehensive income (loss), net of tax. 2020 Lime Investments Our ownership in Lime is comprised of Lime Common Stock, Lime 1-C Preferred Stock, Lime 1-C Preferred Stock Warrants, and the Lime Convertible Note (collectively, the “2020 Lime Investments”). The 2020 Lime Investments were received as part of the transaction by which we divested of our JUMP business. Refer to Note 17 – Divestitures for further information regarding the JUMP Divestiture and the 2020 Lime Investments. Our investment in Lime Common Stock and representation on Lime’s board of directors gives us the ability to exercise significant influence over Lime. We elected to apply the fair value option to our Lime Common Stock investment and therefore we are applying fair value accounting to all of the 2020 Lime Investments which provides for consistency of accounting treatment. The 2020 Lime Investments are measured at fair value on a recurring basis with changes in fair value reflected in earnings. The fair value of the 2020 Lime Investments as of September 30, 2020 of $136 million was determined by referencing a recent transaction in a convertible note that is junior to the Lime Convertible Note and used as an input to an OPM. Other key inputs to the OPM were a discount rate of 22%, volatility of 66% and time to liquidity of 2.0 years. Financial Assets Measured at Fair Value Using Level 3 Inputs The following table presents a reconciliation of our financial assets measured and recorded at fair value on a recurring basis as of September 30, 2020, using significant unobservable inputs (Level 3) (in millions): Non-marketable Non-marketable Equity Security Note Receivable Balance as of December 31, 2018 $ 2,370 $ — $ — Total net gains (losses) Included in earnings (8) 11 — Included in other comprehensive income (loss) 4 — — Purchases (1) 4 56 — Transfers (2) — 31 — Balance as of December 31, 2019 2,370 98 — Total net gains (losses) Included in earnings (27) (87) (8) Included in other comprehensive income (loss) 9 — — Purchases 3 65 91 Impairments — — — Sales (8) (22) — Balance as of September 30, 2020 $ 2,347 $ 54 $ 83 (1) Purchases in non-marketable equity security include warrants to purchase shares of a private company that vest as certain performance criteria are met during the period. (2) Transfers include a non-marketable equity security that was previously measured at fair value on a non-recurring basis as of December 31, 2018 for which we elected to apply the fair value option during the year ended December 31, 2019. Management’s key inputs and assumptions used to determine an estimate of fair value for this investment is based on an OPM and price of the underlying security in recent financing transactions. There is significant uncertainty over the collectability of the contractual interest on the Grab investment and as a result we have elected to apply a non-accrual policy to this investment. In determining whether a non-accrual policy is appropriate, we considered, among other factors, the reasonable possibility of a Grab initial public offering, the ability of Grab to pay the accumulated interest on all preferred securities on or after the redemption date, and the likelihood of a redemption occurring. If we had recorded accrued interest on the Series G preference shares, we would have recognized additional interest income of $36 million and $106 million for the three and nine months ended September 30, 2019, respectively, and $38 million and $113 million for the three and nine months ended September 30, 2020, respectively. Assets Measured at Fair Value on a Non-Recurring Basis Non-Financial Assets Our non-financial assets, such as goodwill, intangible assets and property and equipment are adjusted to fair value when an impairment charge is recognized. Such fair value measurements are based predominately on Level 3 inputs. Non-Marketable Equity Securities Our non-marketable equity securities are investments in privately held companies without readily determinable fair values and primarily relate to our investment in Didi. The carrying value of our non-marketable equity securities are adjusted based on price changes from observable transactions of identical or similar securities of the same issuer (referred to as the measurement alternative) or for impairment. Any changes in carrying value are recorded within other income (expense), net in the condensed consolidated statements of operations. Non-marketable equity securities are classified within Level 3 in the fair value hierarchy because we estimate the fair value of these securities based on valuation methods, including the common stock equivalent (“CSE”) and OPM methods, using the transaction price of similar securities issued by the investee adjusted for contractual rights and obligations of the securities it holds. The following is a summary of unrealized gains and losses from remeasurement (referred to as upward or downward adjustments) recorded in other income (expense), net in the condensed consolidated statements of operations, and included as adjustments to the carrying value of non-marketable equity securities held during the three and nine months ended September 30, 2019 and 2020. The amounts are based on the selling price of newly issued shares of similar preferred stock to new investors using a hybrid method which applies probabilities to possible scenarios valued using the CSE method, and OPM, which contemplates the rights and preferences of the securities we hold. (In millions) Three Months Ended September 30, Nine Months Ended September 30, 2019 2020 2019 2020 Upward adjustments $ — $ — $ 22 $ — Downward adjustments (including impairment) — — — (1,690) Total unrealized gain (loss) for non-marketable equity securities $ — $ — $ 22 $ (1,690) We evaluate our non-marketable equity securities for impairment at each reporting period based on a qualitative assessment that considers various potential impairment indicators. This evaluation consisted of several factors including, but not limited to, an assessment of a significant adverse change in the economic environment, significant adverse changes in the general market condition of the geographies and industries in which our investees operate, and other publicly available information that affected the value of our non-marketable equity securities. As a result of the deterioration in economic and market conditions arising from COVID-19, we determined an impairment indicator existed as of March 31, 2020 and the fair value of certain investments, primarily our investment in Didi, was less than their carrying value. To determine the fair value of our investment in Didi as of March 31, 2020, we utilized a hybrid approach, incorporating a CSE method along with an OPM, weighted at 80% and 20%, respectively. The CSE method assumes an if-converted scenario, where the OPM approach allocates equity value to individual securities within the investees’ capital structure based on contractual rights and preferences. We computed a range of market adjustments based on observed market valuation declines of Didi’s representative stock market indices and publicly-traded competitive peer group since the latest transaction in similar securities occurred in the prior year and prior to the announcement of COVID-19 as a global pandemic, impacting global demand for ridesharing services. These inputs are considered indicative of changes in the fair value of Didi equity. Market adjustments within the range were applied to the Didi equity valuation derived from the latest financing transaction in similar securities which were then used in the CSE and OPM approaches to obtain the fair value of the Didi securities owned by us. A lower adjustment within the range was applied to the enterprise value used in the CSE allocation compared to a higher downward adjustment for purposes of allocating value in the OPM approach. The value adjustment differential was attributable to several factors including possible exit scenarios, as an initial public offering (“IPO”) event would result in higher valuation (due to access to public markets and reduction in cost of capital), reduces valuation uncertainty, and generally assumes market and macro-economic conditions that are comparatively more favorable than an otherwise prolonged stay-private scenario. As a result of the valuation performed, we recorded an impairment charge of $1.7 billion in other income (expense), net in our condensed consolidated statement of operations during the first quarter of 2020. The following table summarizes information about the significant unobservable inputs used in the valuation for our investment in Didi as of March 31, 2020: Fair value method Key unobservable inputs CSE Market adjustment (20)% OPM Volatility 39% Estimated time to liquidity 2.0 years Market adjustment (40)% There was no remeasurement event for the investment in Didi during the three months ended June 30, 2020 and September 30, 2020. We did not record any realized gains or losses for our non-marketable equity securities measured at fair value on a non-recurring basis during the three and nine months ended September 30, 2020. The following table summarizes the total carrying value of our non-marketable equity securities measured at fair value on a non-recurring basis held as of December 31, 2019 and September 30, 2020 including cumulative unrealized upward and downward adjustments made to the initial cost basis of the securities (in millions): As of December 31, 2019 September 30, 2020 Initial cost basis $ 6,075 $ 6,256 Upward adjustments 1,984 1,984 Downward adjustments (including impairment) — (1,690) Total carrying value at the end of the period $ 8,059 $ 6,550

Equity Method Investments and Joint Ventures [Abstract]
Equity Method Investments	Note 4 – Equity Method Investments The carrying value of our equity method investments as of December 31, 2019 and September 30, 2020 were as follows (in millions): As of December 31, 2019 September 30, 2020 MLU B.V. $ 1,224 $ 1,097 Mission Bay 3 & 4 (1) 140 46 Other — 47 Equity method investments $ 1,364 $ 1,190 (1) Refer to Note 14 – Variable Interest Entities (“VIEs”) for further information on our interest in Mission Bay 3 & 4. MLU B.V. During the first quarter of 2018, we closed a transaction that contributed the net assets of our Uber Russia/CIS operations into a newly formed private limited liability company (“MLU B.V.” or “Yandex.Taxi joint venture”), with Yandex and our holding ownership interests in MLU B.V. In exchange for consideration contributed, we received a seat on MLU B.V.’s board and an initial 38% equity ownership interest consisting of common stock in MLU B.V. Certain contingent equity issuances of MLU B.V. may dilute our equity ownership interest to approximately 35%. The investment was determined to be an equity method investment due to our ability to exercise significant influence over MLU B.V. The initial fair value of our equity method investment in MLU B.V. was estimated using discounted cash flows of MLU B.V. During the third quarter of 2020, Yandex contributed its Yandex.Carsharing business (“Drive”) into MLU B.V. in exchange for an additional equity interest. The contribution of Drive into MLU B.V. resulted in the dilution of our ownership in MLU B.V. from 38% to 35%. The gain recognized on the dilution of our interest was not material to our consolidated results of operations for the three months ended September 30, 2020. Our equity ownership interest in MLU B.V. was 35% as of September 30, 2020. For the three and nine months ended September 30, 2020, an immaterial amount of loss was recognized on our MLU B.V. equity method investment. As part of this transaction, MLU B.V. contributed the assets and liabilities of its autonomous driving unit into a new legal entity, Yandex Self Driving Group B.V. (“SDG”), in which Yandex contributed additional capital. The reduction of our ownership interest to 20% in SDG, valued at $42 million, did not result in a material dilution gain. Included in the carrying value of MLU B.V. is the basis difference, net of amortization, between the original cost of the investment and our proportionate share of the net assets of MLU B.V. The carrying value of the equity method investment is primarily adjusted for our share in the income or losses of MLU B.V. and amortization of basis differences. Equity method goodwill and intangible assets, net of accumulated amortization are also adjusted for currency translation adjustments representing fluctuations between the functional currency of the investee, the Ruble and the U.S. Dollar. The Ruble depreciated against the U.S. dollar by approximately 12% between June 30, 2020 and September 30, 2020. The movement in exchange rates will be reflected in the carrying value of the investment with a corresponding adjustment to other comprehensive income (loss) in our consolidated financial statements at December 31, 2020, as we record our share of MLU B.V.’s earnings and reflect our share of MLU B.V.'s net assets on a one-quarter lag basis. The table below provides the composition of the basis difference as of September 30, 2020 (in millions): As of September 30, 2020 Equity method goodwill $ 802 Intangible assets, net of accumulated amortization 93 Deferred tax liabilities (21) Cumulative currency translation adjustments (138) Basis difference $ 736 We amortize the basis difference related to the intangible assets over the estimated useful lives of the assets that gave rise to the difference using the straight-line method. The weighted-average life of the intangible assets is approximate ly 4.2 years as of September 30, 2020. Equity method goodwill is not amortized. The investment balance is reviewed for impairment whenever factors indicate that the carrying value of the equity method investment may not be recoverable. As of September 30, 2020, there was no impairment in our investment of MLU BV. The future effect of the COVID-19 pandemic and related government actions as well as other factors will continue to be monitored. Mission Bay 3 & 4 The Mission Bay 3 & 4 JV refers to Event Center Office Partners, LLC (“ECOP”), a joint venture entity established in March 2018, by Uber and two companies (“LLC Partners”) to manage the construction and operation of two office buildings owned by two ECOP wholly-owned subsidiaries. We contributed $136 million cash in exchange for a 45% interest in ECOP. The two LLC Partners own 45% and 10%, respectively. The amount of contributed cash was recorded as an equity method investment. In March 2020, the two ECOP wholly-owned subsidiaries took out new loans. Upon closing of the new financing, the proceeds were used to first pay off the existing construction loan, then to cover the required operation reserve as well as various financing costs, and last, t he remaining proceeds were distributed back to the Uber and LLC Partners based on their ownership percentage. As a result, Uber received $91 million from the ECOP as a return of capital investment, and reduced the investment carrying value by the same amount. As of September 30, 2020, the equity method investment for Mission Bay 3 & 4 was $46 million. The equity ownership interest in ECOP was 45% as of December 31, 2019 and September 30, 2020. For the three and nine months ended September 30, 2020 , an immaterial amount of equity earnings was recognized. As of December 31, 2019 and September 30, 2020, we determined that there was no impairment of our investment in ECOP.

These operating and finance leases will commence between fiscal years 2020 and 2022 with lease terms ranging from 3 to 11 years. Mission Bay 1 & 2 In 2015, we entered into a joint venture (“JV”) agreement with a real estate developer (“JV Partner”) to develop land (“the Land”) in San Francisco to construct our new headquarters (the “Headquarters”). The Headquarters will consist of two adjacent office buildings totaling approximately 423,000 rentable square feet. In connection with the JV arrangement, we had acquired a 49% interest in the JV, the principal asset of which was the Land. In 2016, we and the JV Partner agreed to dissolve the JV and terminate our commitment to the lease of the Headquarters (together “the real estate transaction”) and we retained a 49% indirect interest in the Land (“Indirect Interest”). Under the terms of the real estate transaction, we obtained the rights and title to the partially constructed building, will complete the development of the two office buildings and retain a 100% ownership in the buildings. In connection with the real estate transaction, we also executed two 75-year land lease agreements (“Land Leases”). As of September 30, 2020, commitments under the Land Leases total $155 million until February 2032. After 2032, the annual rent amount will adjust annually based on the prevailing consumer price index. The real estate transaction is accounted for as a financing transaction of our 49% Indirect Interest due to our continuing involvement through a purchase option on the Indirect Interest. As a financing transaction, the cash and deferred sales proceeds received from the real estate transaction are recorded as a financing obligation. As of September 30, 2020, our Indirect Interest of $65 million is included in property and equipment, net and a corresponding financing obligation of $77 million is included in other long-term liabilities. Future land lease payments of $1.7 billion will be allocated 49% to the financing obligation of the Indirect Interest and 51% to the operating lease of land.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill, Intangible Assets, and Long-Lived Assets	Note 6 – Goodwill, Intangible Assets and Long-Lived Assets Goodwill On January 2, 2020, we completed the acquisition of substantially all of the assets of Careem Inc. (“Careem”) and certain of its subsidiaries. The acquisition was accounted for as a business combination, resulting in the recognition of $2.5 billion in goodwill in our Mobility segment and $540 million in intangible assets. Refer to Note 16 – Business Combinations for further information. On July 6, 2020, we closed on a purchase agreement to acquire Cornershop Global LLC (“CS-Global”), and its wholly owned subsidiaries operating in Brazil, Chile, Colombia, Costa Rica, Canada, U.S., and Peru. The agreement was accounted for as a business combination, resulting in the recognition of $370 million in goodwill in our Delivery segment and $122 million in intangible assets. Refer to Note 16 – Business Combinations for further information. On July 14, 2020, we acquired 100% of the equity of Routematch Holdings, Inc. (“Routematch”). The acquisition was accounted for as a business combination, resulting in the recognition of $89 million in goodwill in our Mobility segment. Refer to Note 16 – Business Combinations for further information. The following table presents the changes in the carrying value of goodwill, by segment, for the nine months ended September 30, 2020 (in millions): Mobility Delivery Freight ATG and Other Technology Programs All Other Total Goodwill Balance as of December 31, 2019 $ 25 $ 13 $ — $ 29 $ 100 $ 167 Acquisitions (Note 16) 2,573 370 — — — 2,943 Goodwill impairment — — — — (100) (100) Foreign currency translation adjustment (22) — — — — (22) Balance as of September 30, 2020 $ 2,576 $ 383 $ — $ 29 $ — $ 2,988 Goodwill Impairment During the three months ended March 31, 2020, prior to the JUMP Divestiture in May 2020, market, macroeconomic and business conditions resulting from the COVID-19 pandemic indicated that it was more likely than not that the carrying value of our New Mobility reporting unit within our previous Other Bets segment (subsequently renamed All Other after the JUMP Divestiture), exceeded its fair value. As a result, we performed an interim goodwill impairment test by comparing the fair value of the New Mobility reporting unit to its carrying value. Fair value was determined by referencing market valuation multiples implied by companies that have comparable businesses which is a Level 3 measurement. The carrying value of our New Mobility reporting unit exceeded its fair value, and as a result, during the three months ended March 31, 2020, a goodwill impairment charge of $100 million was recorded in general and administrative expenses in the condensed consolidated statement of operations, after consideration of impairments of long-lived and other assets of the reporting unit. Further, during the three months ended June 30, 2020, our remaining long-lived assets in the New Mobility asset group that were not transferred to Lime as part of the JUMP Divestiture were impaired resulting in immaterial losses. In light of the impact of the COVID-19 pandemic on macroeconomic conditions and demand for Mobility, we also considered whether it was more likely than not the fair value of our Mobility reporting unit was below its carrying value. Based on an analysis of qualitative and quantitative factors, including market valuation multiples of public companies operating in the same business and considering the significant excess of the fair value attributable to the Mobility reporting unit over its carrying value, we determined that Mobility goodwill was not impaired as of September 30, 2020.

The amendment qualified as a debt modification that did not result in an extinguishment except for an immaterial syndicated amount of the loan. The 2016 Senior Secured Term Loan is guaranteed by certain of our material domestic restricted subsidiaries. The 2016 Senior Secured Term Loan agreement contains customary covenants restricting our and certain of our subsidiaries’ ability to incur debt, incur liens and undergo certain fundamental changes. We were in compliance with all covenants as of September 30, 2020. The credit agreement also contains customary events of default. The loan is secured by certain of our intellectual property and equity of certain material foreign subsidiaries. The 2016 Senior Secured Term Loan also contains restrictions on the payment of dividends. 2018 Senior Secured Term Loan In April 2018, we entered into a secured term loan agreement with a syndicate of lenders to issue secured floating-rate term loans totaling $1.5 billion in proceeds, net of debt discount of $8 million and debt issuance costs of $15 million, with a maturity date of April 2025 (the “2018 Senior Secured Term Loan”). The 2018 Senior Secured Term Loan was issued on a pari passu basis with the existing 2016 Senior Secured Term Loan. The debt discount and debt issuance costs are being amortized to interest expense at an effective interest rate of 6.2%. The 2018 Senior Secured Term Loan is guaranteed by certain of our material domestic restricted subsidiaries. The 2018 Senior Secured Term Loan agreement contains customary covenants restricting our and certain of our subsidiaries’ ability to incur debt, incur liens and undergo certain fundamental changes. We were in compliance with all covenants as of September 30, 2020. The credit agreement also contains customary events of default. The loan is secured by certain of our intellectual property and equity of certain material foreign subsidiaries. The fair values of our 2016 Senior Secured Term Loan and the 2018 Senior Secured Term Loan were $1.1 billion and $1.5 billion, respectively, as of September 30, 2020 and were determined based on quoted prices in markets that are not active, which is considered a Level 2 valuation input.

In conjunction with our entry into the 2016 Senior Secured Term Loan, the revolving credit facility agreements were amended to include as collateral the same intellectual property of Uber and the same equity of certain material foreign subsidiaries that were pledged as collateral under the 2016 Senior Secured Term Loan. The credit facility may be guaranteed by certain of our material domestic restricted subsidiaries based on certain conditions. The credit agreement contains customary covenants restricting our and certain of our subsidiaries’ ability to incur debt, incur liens, and undergo certain fundamental changes, as well as maintain a certain level of liquidity specified in the contractual agreement. The credit agreement also contains customary events of default. The Revolving Credit Facility also contains restrictions on the payment of dividends. As of September 30, 2020, there was no balance outstanding on the Revolving Credit Facility. Letters of Credit Our insurance subsidiary maintains agreements for letters of credit to guarantee the performance of insurance related obligations that are collateralized by cash or investments of the subsidiary. For purposes of securing obligations related to leases and other contractual obligations, we also maintain an agreement for letters of credit, which is collateralized by our Revolving Credit Facility and reduces the amount of credit available. As of December 31, 2019 and September 30, 2020, we had letters of credit outstanding of $570 million and $632 million, respectively, of which the letters of credit that reduced the available credit under the Revolving Credit Facility were $213 million and $213 million, respectively.

Stockholder's Equity

Stockholder's Equity	3 Months Ended

Equity [Abstract]
Stockholder's Equity	Note 9 – Stockholders' Equity Equity Compensation Plans We maintain four equity compensation plans that provide for the issuance of shares of our common stock to our officers and other employees, directors, and consultants: the 2010 Stock Plan (the “2010 Plan”), the 2013 Equity Incentive Plan (the “2013 Plan”), the 2019 Equity Incentive Plan (the “2019 Plan”), and the 2019 Employee Stock Purchase Plan (the “ESPP”), which have all been approved by stockholders. Following our IPO, we have only issued awards under the 2019 Plan and the ESPP, and no additional awards will be granted under the 2010 and 2013 Plans. These plans provide for the issuance of incentive stock options (“ISOs”), nonqualified stock options (“NSOs”), stock appreciation rights (“SARs”), restricted stock, restricted stock units (“RSUs”), performance-based awards, and other awards (that are based in whole or in part by reference to our common stock). Initial Public Offering On May 14, 2019, we closed our IPO, in which we issued and sold 180 million shares of our common stock. The price was $45.00 per share. We received net proceeds of approximately $8.0 billion from the IPO after deducting underwriting discounts and commissions of $106 million and offering expenses. Upon closing of the IPO: (i) all shares of our outstanding redeemable convertible preferred stock automatically converted into 905 million shares of common stock; (ii) holders of the 2021 and 2020 convertible notes elected to convert all outstanding notes into 94 million shares of common stock; and, (iii) an outstanding warrant which became exercisable upon the closing of the IPO was exercised to purchase 0.2 million shares of common stock. In addition, we recognized a net gain of $327 million in other income (expense), net in the condensed consolidated statement of operations upon conversion of the 2021 and 2022 convertible notes during the second quarter of 2019, which consisted of $444 million gain on extinguishment of debt and settlement of derivatives, partially offset by $117 million loss from the change in fair value of embedded derivatives prior to settlement. The extinguishment of debt resulted in the derecognition of the carrying value of the debt balance and settlement of embedded derivatives. We had granted RSAs, RSUs, SARs, and stock options that vest only upon the satisfaction of both time-based service and performance-based conditions. Through May 9, 2019, no stock-based compensation expense had been recognized for such awards with a performance condition based on the occurrence of a qualifying event (such as an IPO), as such qualifying event was not probable. Upon our IPO, we recognized $3.6 billion of stock-based compensation expense. Upon the IPO, shares were issued to satisfy the vesting of RSUs with a performance condition. To meet the related tax withholding requirements, we withheld 29 million of the 76 million shares of common stock issued. Based on the IPO public offering price of $45.00 per share, the tax withholding obligation was $1.3 billion. As a result of stock-based compensation expense for vested and unvested RSUs upon the IPO, we recorded an additional deferred tax asset of approximately $1.1 billion that is offset by a full valuation allowance. PayPal Private Placement On May 16, 2019, we closed a private placement by PayPal, Inc. (“PayPal”) in which we issued and sold 11 million shares of our common stock at a purchase price of $45.00 per share and received aggregate proceeds of $500 million. Additionally, we and PayPal ag reed to extend our global partnership, including a commitment to jointly explore certain commercial collaborations.

The unamortized compensation costs are expected to be recognized over a weighted-average period of approximately 2.84 years. The tax benefits recognized in the condensed consolidated statements of operations for stock-based compensation arrangements were not material during the three and nine months ended September 30, 2019 and 2020, respectively. ESPP During the second quarter of 2020, 3 million shares of common stock were purchased under the ESPP at a weighted-average price of $25.05 per share, resulting in cash proceeds of $82 million.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Note 10 – Income Taxes We com pute our quarterly income tax expense/(benefit) by using a forecasted annual effective tax rate and adjust for any discrete items arising during the quarter. We recorded an income tax expense of $3 million and $20 million for the three and nine months ended September 30, 2019, respectively, and an income tax expense of $23 million and income tax benefit of $(215) million for the three and nine months ended September 30, 2020, respectively. During the three and nine months ended September 30, 2019, income tax expense was primarily driven by current tax on foreign earnings offset by a partial benefit from U.S. losses. During the three months ended September 30, 2020, the income tax expense was primarily driven by current tax on foreign earnings offset by a partial benefit from U.S. losses. During the nine months ended September 30, 2020, the income tax benefit was primarily driven by the deferred U.S. tax impact of the impairment charges related to our investment in Didi, the deferred China tax impact of the impairment charge related to our investment in Didi, and to a lesser extent, the benefit of U.S. losses and current tax on foreign earnings. The primary differences between the effective tax rate and the federal statutory tax rate are due to the valuation allowance on our U.S. and Netherlands’ deferred tax assets, foreign tax rate differences, and the benefit from the impairment charges related to our investment in Didi. In the second quarter of 2020, we transferred certain intangible assets among our wholly-owned subsidiaries to align our structure to our evolving operations. The transaction resulted in the establishment of deferred tax assets of $308 million; however, there was no financial statement benefit recognized since the deferred tax asset was offset by a full valuatio n allowance. During the nine months ended September 30, 2020, the amount of gross unrecognized tax benefits increased by $182 million, of which substantially all, if recognized, would not affect the effective tax rate as these unrecognized tax benefits would increase deferred tax assets that would be subject to a full valuation allowance. We are subject to taxation in the United States and various state and foreign jurisdictions. We are also under routine examination by federal, various state, and foreign tax authorities. We believe that adequate amounts have been reserved in these jurisdictions. To the extent we have tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by federal, state or foreign tax authorities to the extent utilized in a future period. For our major tax jurisdictions, the tax years 2010 through 2020 remain open; the major tax jurisdictions are the U.S., Brazil, Netherlands, United Kingdom, Australia, and India. Although the timing of the resolution and/or closure of audits is highly uncertain, we do not expect any material changes to our unrecognized tax benefits within the next 12 months. Given the number of years remaining subject to examination and the number of matters being examined, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. In the event we experience an ownership change within the meaning of Section 382 of the Internal Revenue Code (“IRC”), our ability to utilize net operating losses, tax credits and other tax attributes may be limited. The most recent analysis of our historical ownership changes was completed through September 30, 2020. Based on the analysis, we do not anticipate a current limitation on the tax attributes. In response to the Coronavirus pandemic, governments in certain countries have enacted legislation, including the Coronavirus Aid, Relief, and Economic Security Act enacted by the United States on March 27, 2020. Recent legislative developments did not have a material impact on our provision for income tax.

Earnings Per Share [Abstract]
Net Loss Per Share	Note 11 – Net Loss Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period presented. Diluted net income (loss) per share is computed by giving effect to all potential weighted average dilutive common stock. The dilutive effect of outstanding awards and convertible securities is reflected in diluted net income (loss) per share by application of the treasury stock method. The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders (in millions, except share amounts which are reflected in thousands, and per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2019 2020 2019 2020 Basic net loss per share: Numerator Net loss including non-controlling interests $ (1,159) $ (1,108) $ (7,421) $ (5,826) Less: net income (loss) attributable to non-controlling interests, net of tax (3) 19 11 27 Net loss attributable to common stockholders $ (1,162) $ (1,089) $ (7,410) $ (5,799) Denominator Basic weighted-average common stock outstanding 1,700,213 1,755,029 1,092,241 1,739,488 Basic net loss per share attributable to common stockholders (1) $ (0.68) $ (0.62) $ (6.79) $ (3.33) Diluted net loss per share: Numerator Diluted net loss attributable to common stockholders $ (1,162) $ (1,089) $ (7,410) $ (5,799) Denominator Diluted weighted-average common stock outstanding 1,700,213 1,755,029 1,092,241 1,739,488 Diluted net loss per share attributable to common stockholders (1) $ (0.68) $ (0.62) $ (6.79) $ (3.33) (1) Per share amounts are calculated using unrounded numbers and therefore may not recalculate. On May 14, 2019, we completed our IPO, in which we issued and sold 180 million shares of our common stock at a price of $45.00 per share. On that date, all of our outstanding redeemable convertible preferred stock automatically converted into 905 million shares of common stock, and the holders of the 2021 and 2022 convertible notes elected to convert the outstanding notes into common stock, resulting in the issuance of 94 million shares of common stock. These shares were included in our issued and outstanding common stock starting on that date. Refer to Note 9 – Stockholders' Equity for additional information on our IPO. The following potentially dilutive outstanding securities were excluded from the computation of diluted net loss per share because their effect would have been anti-dilutive for the periods presented, or issuance of such shares is contingent upon the satisfaction of certain conditions which were not satisfied by the end of the period (in thousands): As of September 30, 2019 2020 Stock options 40,532 25,492 Common stock subject to repurchase 828 28 RSUs to settle fixed monetary awards 325 109 RSUs 91,284 93,508 Shares committed under ESPP 5,012 2,016 Warrants to purchase common stock 187 126 Careem convertible notes — 14,181 Total 138,168 135,460

Segment Reporting [Abstract]
Segment Information and Geographic Information	Note 12 – Segment Information and Geographic Information We determine our operating segments based on how the chief operating decision maker (“CODM”) manages the business, allocates resources, makes operating decisions and evaluates operating performance. During the second quarter of 2020, we changed the name of the Rides segment to Mobility and the name of the Eats segment to Delivery. In addition, during the second quarter of 2020, we completed the divestiture of our JUMP business (the “JUMP Divestiture”), which comprised substantially all of the operations of our Other Bets reportable segment. Subsequent to the JUMP Divestiture, the Other Bets segment no longer exists and the continuing activities previously included in the Other Bets segment are immaterial for all periods presented. Certain of these other continuing business activities were migrated to our Mobility segment, whose prior period results were not restated because such business activities were immaterial. The other business activities that were not migrated represent an “all other category separate from other reconciling items” and are presented within the All Other caption. The historical results of the former Other Bets segment are included within the All Other caption. Refer to Note 17 – Divestitures for further information regarding the JUMP Divestiture. As of the second quarter of 2020, our four operating and reportable segments are as follows: Segment Description Mobility Mobility products connect consumers with Drivers who provide rides in a variety of vehicles, such as cars, auto rickshaws, motorbikes, minibuses, or taxis. Mobility also includes activity related to our U4B, Financial Partnerships, Transit and Vehicle Solutions offerings. Delivery Delivery offerings allow consumers to search for and discover local restaurants, order a meal, and either pick-up at the restaurant or have the meal delivered. In certain markets, Delivery also includes offerings for grocery and convenience store delivery as well as select other goods. Freight Freight connects carriers with shippers on our platform, and gives carriers upfront, transparent pricing and the ability to book a shipment. ATG and Other Technology Programs The ATG and Other Technology Programs segment is responsible for the development and commercialization of autonomous vehicle and ridesharing technologies, as well as Uber Elevate. For information about how our reportable segments derive revenue, refer to Note 2 – Revenue. Our segment operating performance measure is segment adjusted EBITDA. The CODM does not evaluate operating segments using asset information and, accordingly, we do not report asset information by segment. Segment adjusted EBITDA is defined as revenue less the following expenses: cost of revenue, operations and support, sales and marketing, and general and administrative and research and development expenses associated with our segments. Segment adjusted EBITDA also excludes non-cash items or items that management does not believe are reflective of our ongoing core operations (as shown in the table below). The following table provides information about our segments and a reconciliation of the total segment adjusted EBITDA to loss from operations (in millions): Three Months Ended September 30, Nine Months Ended September 30, 2019 2020 2019 2020 Segment adjusted EBITDA: Mobility $ 631 $ 245 $ 1,329 $ 876 Delivery (316) (183) (911) (728) Freight (81) (73) (162) (186) ATG and Other Technology Programs (124) (104) (369) (303) All Other (72) — (184) (86) Total segment adjusted EBITDA 38 (115) (297) (427) Reconciling items: Corporate G&A and Platform R&D (1), (2) (623) (510) (1,813) (1,647) Depreciation and amortization (102) (138) (371) (395) Stock-based compensation expense (401) (183) (4,353) (591) Legal, tax, and regulatory reserve changes and settlements 27 — (353) (57) Driver appreciation award — — (299) — Payroll tax on IPO stock-based compensation — — (86) — Goodwill and asset impairments/loss on sale of assets (3) — (76) (8) (285) Acquisition, financing and divestitures related expenses — (14) — (43) Accelerated lease costs related to cease-use of ROU assets (3) — (80) — (80) COVID-19 response initiatives — (18) — (90) Gain on lease arrangement, net — 12 — 5 Restructuring and related credits (charges) (45) 6 (45) (376) Loss from operations $ (1,106) $ (1,116) $ (7,625) $ (3,986) (1) Excluding stock-based compensation expense.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 13 – Commitments and Contingencies Purchase Commitments We have commitments for network and cloud services, background checks, and other items in the ordinary course of business with varying expiration terms through 2024. These amounts are determined based on the non-cancelable quantities or termination amounts to which we are contractually obligated. In July 2020, we entered into a commercial technology agreement with Google LLC for a term of four years. We are committed to spend an aggregate of at least $160 million for the period from July 2020 through June 2024. Aside from the above, as of September 30, 2020, there were no material changes to our purchase commitments disclosed in the financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2019. Contingencies From time to time, we are a party to various claims, non-income tax audits and litigation in the normal course of business. As of December 31, 2019 and September 30, 2020, we had recorded aggregate liabilities of $1.5 billion and $1.7 billion, respectively, in accrued and other current liabilities on the condensed consolidated balance sheets for all of our legal, regulatory and non-income tax matters that were probable and reasonably estimable. We are currently party to various legal and regulatory matters that have arisen in the normal course of business and include, among others, alleged independent contractor misclassification claims, Fair Credit Reporting Act (“FCRA”) claims, alleged background check violations, pricing and advertising claims, unfair competition claims, intellectual property claims, employment discrimination and other employment-related claims, Telephone Consumer Protection Act (“TCPA”) claims, Americans with Disabilities Act (“ADA”) claims, data and privacy claims, securities claims, antitrust claims, challenges to regulations, and other matters. We have existing litigation, including class actions, PAGA lawsuits, arbitration claims, and governmental administrative and audit proceedings, asserting claims by or on behalf of Drivers that Drivers are misclassified as independent contractors. In connection with the enactment of California State Assembly Bill 5 (“AB5”), we have received and expect to continue to receive - in California and in other jurisdictions - an increased number of misclassification claims. With respect to our outstanding legal and regulatory matters, based on our current knowledge, we believe that the ultimate amount or range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on our business, financial position, results of operations, or cash flows. The outcome of such legal matters is inherently unpredictable and subject to significant uncertainties. If one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations, financial condition or cash flows could be materially adversely affected. Driver Classification California Attorney General Lawsuit In January 2020, AB5 went into effect. AB5 codifies a test to determine whether a worker is an employee under California law. The test is referred to as the “ABC” test, and was originally handed down by the California Supreme Court in Dynamex Operations v. Superior Court in 2018. Under the ABC test, workers performing services for a hiring entity are considered employees unless the hiring entity can demonstrate three things: the worker (A) is free from the hiring entity’s control, (B) performs work that is outside the usual course of the hiring entity’s business, and (C) customarily engages in the independent trade, work or type of business performed for the hiring entity. On May 5, 2020, the California Attorney General, in conjunction with the city attorneys for San Francisco, Los Angeles and San Diego, filed a complaint in San Francisco Superior Court against Uber and Lyft, Inc. (“Lyft”). The complaint alleges drivers are misclassified, and seeks an injunction and monetary damages related to the alleged competitive advantage caused by the alleged misclassification of drivers. On August 10, 2020, the Court issued a preliminary injunction order prohibiting us from classifying drivers as independent contractors and from violating various wage and hour laws. The injunction was stayed pending appeal. On October 22, 2020, the Court of Appeal affirmed the lower court’s ruling and held that we must comply with the preliminary injunction order no later than 30 days after the case is returned to the trial court. In November 2020, California voters voted on Proposition 22, a state ballot initiative that provides a framework for drivers that use platforms like ours for independent work. Based on the unofficial results published by the California Secretary of State as of the date of the issuance of these condensed consolidated financial statements, Proposition 22 was approved, which means that the preliminary injunction will not go into effect and that Drivers will be able to maintain their status as independent contractors under California law and we and our competitors will be required to comply with the provisions of Proposition 22. We expect that Proposition 22 will go into effect in the fourth quarter of 2020; however, for periods prior to its effectiveness and with respect to the California Attorney General’s lawsuit, we continue to intend to vigorously defend ourselves. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. Massachusetts Attorney General Lawsuit On July 9, 2020, the Massachusetts Attorney General filed a complaint in Suffolk County Superior Court against Uber and Lyft. The complaint alleges Drivers are employees, and are entitled to protections under the wage and labor laws. The complaint was served on July 20, 2020 and Uber filed a motion to dismiss the complaint on September 24, 2020. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. Swiss Social Security Reclassification Several Swiss local government bodies have issued decisions in which they classify Drivers as employees of Uber Switzerland, Rasier Operations B.V. or of Uber B.V. for social security or regulatory purposes. We are challenging each of them. In rulings issued on July 20, 2018 and October 9, 2020, the Social Security Tribunal of Zurich confirmed that Uber Switzerland could not be held liable. Proceedings will therefore only proceed with Uber B.V. and Rasier Operations BV and first instance rulings should be issued in the next few months. Further, another Swiss governmental body of the Canton of Geneva ruled on October 30, 2019 that Uber B.V. should be qualified as a transportation company based on the view that Uber B.V. is the employer of Drivers. We appealed this decision. In April 2020, a ruling was made on a separate matter in Switzerland which reclassified a Driver as an employee. The ultimate resolution of the social security matters is uncertain and the amount accrued for this matter is recorded within accrued and other current liabilities on the condensed consolidated balance sheets. Aslam, Farrar, Hoy and Mithu v. Uber B.V., Uber Britannia Ltd. and Uber London Ltd. On October 28, 2015, a claim by 25 Drivers, including Mr. Y. Aslam and Mr. J. Farrar, was brought in the UK Employment Tribunal against us asserting that they should be classified as “workers” (a separate category between independent contractors and employees) in the UK rather than independent contractors. The tribunal ruled on October 28, 2016 that Drivers are workers whenever our app is switched on and they are ready and able to take trips based on an assessment of the app in July 2016. The Court of Appeal rejected our appeal in a majority decision on December 19, 2018. We have appealed to the Supreme Court. A hearing at the Supreme Court took place in July 2020 with a decision expected in the fall of 2020. The plaintiffs have not quantified their claim and if they are successful in establishing “worker” status, any damages will be considered at a future hearing. The amount of compensation sought by the plaintiffs in the case is not currently known. If Drivers are determined to be workers, they may be entitled to additional benefits and payments, which may include pension contributions. Additional claims have been filed, which are stayed pending the judgment of the Supreme Court. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. Other Driver Classification Matters Additionally, we have received other lawsuits and governmental inquiries in other jurisdictions, and anticipate future claims, lawsuits, arbitration proceedings, administrative actions, and government investigations and audits challenging our classification of Drivers as independent contractors and not employees. We believe that our current and historical approach to classification is supported by the law and intend to continue to defend ourselves vigorously in these matters. However, the results of litigation and arbitration are inherently unpredictable and legal proceedings related to these claims, individually or in the aggregate, could have a material impact on our business, financial condition, results of operations and cash flows. Regardless of the outcome, litigation and arbitration of these matters can have an adverse impact on us because of defense and settlement costs individually and in the aggregate, diversion of management resources and other factors. State Unemployment Taxes In December 2016, following an audit opened in 2014 investigating whether Drivers were independent contractors or employees, we received a Notification of Assessment from the Employment Development Department, State of California, for payroll tax liabilities. The notice retroactively imposed various payroll tax liabilities on us, including unemployment insurance, employment training tax, state disability insurance, and personal income tax. We have filed a petition with an administrative law judge of the California Unemployment Insurance Appeals Board appealing the assessment. This matter remains pending. In 2018, the New Jersey Department of Labor (“NJDOL”) opened an audit reviewing whether Drivers were independent contractors or employees for purposes of determining whether unemployment insurance regulations apply from 2014 through 2018. The NJDOL made an assessment on November 12, 2019, against both Rasier and Uber. Both assessments were calculated through November 15, 2019, but only calculated the alleged contributions, penalties, and interests owed from 2014 through 2018. We are engaged in ongoing discussions with the NJDOL about the assessments, though the NJDOL has noticed Uber for a hearing on the merits. Our chances of success on the merits are still uncertain and any reasonably possible loss or range of loss cannot be estimated. Google v. Levandowski & Ron; Google v. Levandowski On October 28, 2016, Google filed arbitration demands against each of Anthony Levandowski and Lior Ron, former employees of Google, alleging breach of their respective employment agreements with Google, fraud and other state law violations (due to soliciting Google employees and starting a new venture to compete with Google’s business in contravention of their respective employment agreements). Google sought damages, injunctive relief, and restitution. On March 26, 2019, following a hearing, the arbitration panel issued an interim award, finding against each of Google’s former employees and awarding $127 million against Anthony Levandowski and $1 million for which both Anthony Levandowski and Lior Ron are jointly and severally liable. In July 2019, Google submitted its request for interest, attorneys fees, and costs related to these claims. The Panel’s Final Award was issued on December 6, 2019. On February 7, 2020, Ron and Google entered into a settlement agreement and mutual release to satisfy the corrected final award in the amount of approximately $10 million. Uber paid Google on behalf of Ron pursuant to an indemnification obligation. A dispute continues to exist with regard to Uber’s alleged indemnification obligation to Levandowski. Whether Uber is ultimately responsible for indemnification of Levandowski depends on the exceptions and conditions set forth in the indemnification agreement. In March 2020, Levandowski pleaded guilty to criminal trade secret charges and filed for bankruptcy. Uber filed a proof of claim in the bankruptcy court, and Levandowski additionally asserted a claim against Uber alleging that Uber failed to perform its obligations under an agreement with Otto Trucking, LLC. The indemnification dispute and Levandowski’s claim will proceed in the bankruptcy court. The ultimate resolution of the matter could result in a possible loss of up to $60 million or more (depending on interest incurred) in excess of the amount accrued. Taiwan Regulatory Fines Prior to us adjusting and re-launching our operating model in April 2017 to a model where government-approved rental companies provide transport services to Riders, Drivers in Taiwan and the local Uber entity were fined by Taiwan’s Directorate General of Highways in significant numbers across Taiwan. On January 6, 2017, a new Highways Act came into effect in Taiwan which increased maximum fines from New Taiwan Dollar (“NTD”) 150,000 to NTD 25 million per offense. We suspended our service in Taiwan from February 10, 2017 to April 12, 2017, but a number of these fines were issued to the local Uber entity in connection with rides that took place in January and February 2017 prior to the suspension. These fines have remained outstanding while Uber appeals the tickets through the courts. In June 2020, we agreed to make periodic payments of approximately $60 million in fines to the Enforcement Agency (“Payment Plan”) stemming from the peer-to-peer business operated until 2017. On September 18, 2020, the Grand Chamber of the Supreme Court announced a positive ruling finding that the agency that issued these fines against the local Uber entity did not have the jurisdiction to do so. As a result of the Grand Chamber’s decision, the Enforcement Agency has agreed to stop all enforcement actions, which includes enforcement against the Payment Plan. We expect rulings from individual Supreme Court chambers to revoke the tickets issued by the agency by early 2021. Although the tickets may be revoked by the Supreme Court, the municipal government that has jurisdiction may reissue new tickets. Depending on the number of tickets reissued by the municipal government, the amount of fines to be paid by Uber could be reduced. Non-Income Tax Matters We recorded an estimated liability for contingencies related to non-income tax matters and are under audit by various domestic and foreign tax authorities with regard to such matters. The subject matter of these contingent liabilities and non-income tax audits primarily arises from our transactions with Drivers, as well as the tax treatment of certain employee benefits and related employment taxes. In jurisdictions with disputes connected to transactions with Drivers, disputes involve the applicability of transactional taxes (such as sales, value added and similar taxes) to services provided, as well as the applicability of withholding tax on payments made to such Drivers. For example, we are involved in a proceeding in the UK involving HMRC, the tax regulator in the UK, which is seeking to classify us as a transportation provider. Being classified as a transportation provider would result in a VAT (20%) on Gross Bookings or on the service fee that we charge Drivers, both retroactively and prospectively. Further, if Drivers are determined to be workers, they may be entitled to additional benefits and payments, and we may be subject to penalties, back taxes, and fines. We believe that the position of HMRC and the regulators in similar disputes and audits is without merit and are defending our positions vigorously. During the first quarter of 2020, we favorably resolved a state non-income exposure in the U.S. resulting in a $138 million reduction of U.S. non-income tax reserves. Our estimated liability is inherently subjective due to the complexity and uncertainty of these matters and the judicial processes in certain jurisdictions, therefore, the final outcome could be different from the estimated liability recorded. Other Legal and Regulatory Matters We have been subject to various government inquiries and investigations surrounding the legality of certain of our business practices, compliance with antitrust, foreign corrupt practices act and other global regulatory requirements, labor laws, securities laws, data protection and privacy laws, the adequacy of disclosures to investors and other shareholders, and the infringement of certain intellectual property rights. We have investigated many of these matters and we are implementing a number of recommendations to our managerial, operational and compliance practices, as well as strengthening our overall governance structure. In many cases, we are unable to predict the outcomes and implications of these inquiries and investigations on our business which could be time consuming, costly to investigate and require significant management attention. Furthermore, the outcome of these inquiries and investigations could negatively impact our business, reputation, financial condition and operating results, including possible fines and penalties and requiring changes to operational activities and procedures. Indemnifications In the ordinary course of business, we often include standard indemnification provisions in our arrangements with third parties. Pursuant to these provisions, we may be obligated to indemnify such parties for losses or claims suffered or incurred in connection with its activities or non-compliance with certain representations and warranties made by us. In addition, we have entered into indemnification agreements with our officers, directors, and certain current and former employees, and our certificate of incorporation and bylaws contain certain indemnification obligations. It is not possible to determine the maximum potential loss under these indemnification provisions / obligations because of the unique facts and circumstances involved in each particular situation.

Variable Interest Entity [Abstract]
Variable Interest Entities (VIEs)	Note 14 – Variable Interest Entities (“VIEs”) Consolidated VIEs We consolidate VIEs in which we hold a variable interest and are the primary beneficiary. We have determined that these entities are a VIE as they lack sufficient equity to finance their activities without future subordinated support. We are the primary beneficiary because we have the power to direct the activities that most significantly impact the economic performance of these VIEs. As a result, we consolidate the assets and liabilities of these VIEs. Total assets included on the condensed consolidated balance sheets for our consolidated VIEs as of December 31, 2019 and September 30, 2020 were $1.2 billion and $1.1 billion, respectively. Total liabilities included on the condensed consolidated balance sheets for these VIEs as of December 31, 2019 and September 30, 2020 were $159 million and $203 million, respectively. Freight Holding In July 2018, we created a new majority-owned subsidiary, Uber Freight Holding Corporation (“Freight Holding”). The purpose of Freight Holding is to perform the business activities of the Freight operating segment. Freight Holding and the Freight Holding stock held by us was determined to be a variable interest. As of September 30, 2020, we continue to own the majority of the issued and outstanding capital stock of Freight Holding and report non-controlling interests as further described in Note 15 – Non-Controlling Interests. Apparate USA LLC In April 2019, we contributed certain of our subsidiaries and certain assets and liabilities related to our autonomous vehicle technologies to Apparate USA LLC (“Apparate”) in exchange for common units representing 100% ownership interest in Apparate. The purpose of Apparate is to develop and commercialize autonomous vehicle and ridesharing technologies. Subsequent to the formation of Apparate, Apparate entered into a Class A Preferred Unit Purchase Agreement (“Preferred Unit Purchase Agreement”) with SVF Yellow (USA) Corporation (“SoftBank”), Toyota Motor North America, Inc. (“Toyota”), and DENSO International America, Inc. (“DENSO”). Preferred units were issued in July 2019 to SoftBank, Toyota, and DENSO and provided the investors with an aggregate 13.8% initial ownership interest in Apparate on an as-converted basis. The common units held by us in Apparate were determined to be a variable interest. Refer to Note 15 – Non-Controlling Interests for further information on our non-controlling interests in Apparate. Careem Pakistan, Qatar and Morocco On January 2, 2020, we completed the acquisition of substantially all of the assets of Careem and certain of its subsidiaries pursuant to an asset purchase agreement (the “Asset Purchase Agreement”) in countries where regulatory approval was obtained or which did not require regulatory approval. The assets and operations in Qatar and Morocco (collectively “Non-Transferred Countries”), have not yet been transferred to us as of September 30, 2020. Transfer of the assets and operations of the Non-Transferred Countries will be subject to a delayed closing pending timing of regulatory approval. If regulatory approval is not obtained with respect to any Non-Transferred Countries by the nine month anniversary of January 2, 2020, we can divest the net assets of any such remaining Non-Transferred Countries and we will receive all the proceeds from the divestiture of any Non-Transferred Countries. In February 2020, regulatory approval in Pakistan was obtained and legal transfer of the assets was completed on July 22, 2020, at which point Careem's operations in Pakistan became a 100% owned subsidiary. Only Qatar and Morocco remain as countries in which Careem continues to operate but where regulatory approval has not yet been obtained as of September 30, 2020. We will continue to seek regulatory approval for Qatar and Morocco. The net assets and operations in Qatar and Morocco are not material. The purpose of the Non-Transferred Countries’ operations is to provide primarily ridesharing services in each respective country. Although the assets and operations of the Non-Transferred Countries were not transferred as of September 30, 2020, we have rights to all residual interests in the entities comprising the Non-Transferred Countries which is considered a variable interest. We are exposed to losses and residual returns of the entities comprising the Non-Transferred Countries through the right to all of the proceeds from either the divestiture or the eventual legal transfer upon regulatory approval of the entities comprising the Non-Transferred Countries. We control Intellectual Properties (“IP”) which are significant for the business of Non-Transferred Countries and sub-license those IP to the Non-Transferred Countries. Each entity that comprises the Non-Transferred Countries meets the definition of a VIE and we are the primary beneficiary of each of the entities comprising the Non-Transferred Countries. As a result, we consolidate the entities comprising the Non-Transferred Countries as further described in Note 16 – Business Combinations. Unconsolidated VIEs Zomato Zomato is incorporated in Indi a with the purposes of providing food delivery services, and operates globally in over 10,000 cities. On January 21, 2020, we acquired compulsorily convertible cumulative preference shares (“CCPS Preferred Shares”) of Zomato valued at $171 million in exchange for Uber’s food delivery operations in India (“Uber Eats India”), and a note receivable valued at $35 million for reimbursement of goods and services tax. Our investment in the CCPS Preferred Shares of Zomato will represent 9.99% of the voting capital upon conversion to ordinary shares. Zomato is a VIE as it lacks sufficient equity to finance its activities without future subordinated financial support. We are exposed to Zomato’s economic risks and rewards through our investment and note receivable which represent variable interests, and the carrying values of these variable interests reflect our maximum exposure to loss. However, we are not the primary beneficiary because neither the investment in CCPS Preferred Shares nor the note receivable provide us with the power to direct the activities that most significantly impact Zomato’s economic performance. As of September 30, 2020, the carrying amount of assets recognized on the condensed consolidated balance sheet related to our interests in Zomato and our maximum exposure to loss relating to this unconsolidated VIE was approximately $200 million. Refer to Note 17 – Divestitures for further information regarding Zomato and the divestiture of Uber Eats India. Mission Bay 3 & 4 The Mission Bay 3 & 4 JV refers to ECOP, a joint venture entity established in March 2018, by us and the LLC Partners. We contributed $136 million cash in exchange for a 45% interest in ECOP. Prior to March 31, 2020, any remaining construction costs were to be funded through a construction loan obtained by ECOP where we together with the two LLC Partners guaranteed payments and performance of the loan when it became due and any payment of costs incurred by the lender under limited situations. As of December 31, 2019, the maximum collective guarantee liability was up to $50 million. We evaluated the nature of our investment in ECOP and determined that ECOP was a VIE during the construction period; however, we were not the primary beneficiary as decisions were made jointly between parties and therefore we did not have the power to direct activities that most significantly impacted the VIE. The investment was determined to be an equity method investment due to our ability to exercise significant influence over ECOP. Refer to Note 4 – Equity Method Investments for further information. In March 2020, ECOP secured new loans and $91 million was distributed back to us as a return of capital investment. In connection with the repayment of the construction loan by ECOP, the maximum collective guarantee liability of up to $50 million was extinguished. We reevaluate if ECOP meets the definition of a VIE upon specific reconsideration events. The closing of ECOP's new financing in March 2020, triggered a reconsideration event and we reevaluated if ECOP still met the definition of a VIE. As of March 31, 2020, we determined that ECOP was no longer a VIE as it has sufficient equity to operate without the need for subordinated financial support. Lime On May 7, 2020, we entered into the JUMP Divestiture. Refer to Note 17 – Divestitures for further information on the JUMP Divestiture. Lime is a VIE as it lacks sufficient equity to finance its activities without future subordinated financial support. We are exposed to Lime’s economic risks and rewards through our ownership of the 2020 Lime Investments, which represent variable interests. However, we are not the primary beneficiary of Lime because we lack the power to direct the activities that most significantly impact Lime’s economic performance. As of September 30, 2020, the carrying amount of assets recognized on our condensed consolidated balance sheet related to the 2020 Lime Investments of $136 million represents our maximum exposure to loss associated with Lime as an unconsolidated VIE. Cornershop: CS-Mexico On July 6, 2020, we closed on a purchase agreement with CS-Global, excluding operating subsidiaries in Mexico (“CS-Mexico”). Refer to Note 16 – Business Combinations for further information. CS-Mexico is a VIE as its equity interests do not fully absorb the entity’s expected losses and it lacks sufficient equity to finance its activities without future subordinated financial support. We are exposed to CS-Mexico’s economic risks and rewards through: the CS-Mexico Put/Call; an immaterial unsecured note; the contractual rights to 35% of contingent sale proceeds from CS-Mexico under certain conditions; and a market-based fee related to the transition services agreement, all of which represent variable interests held by Uber. However, we are not the primary beneficiary because the variable interests do not provide us with the power to direct the activities that most significantly impact CS-Mexico’s economic performance. As of September 30, 2020, the carrying amount of assets recognized on the condensed consolidated balance sheet related to our interests in CS-Mexico is $28 million and our maximum exposure to loss relating to this unconsolidated VIE were approximately $23 million.

Noncontrolling Interest [Abstract]
Non-Controlling Interests	Note 15 – Non-Controlling Interests ATG Investment: Preferred Unit Purchase Agreement In July 2019, we closed a Preferred Unit Purchase Agreement with SoftBank, Toyota, and DENSO (collectively “the Investors”) for purchase by the Investors of Class A Preferred Units (“Preferred Units”) in Apparate. Apparate, a subsidiary of ours, issued 1.0 million Preferred Units at $1,000 per unit to the Investors for an aggregate consideration of $1.0 billion ($400 million from Toyota, $333 million from SoftBank, and $267 million from DENSO). As of September 30, 2020, the Preferred Units represented an aggregate 14.3% ownership interest in Apparate on an as-converted basis. As of September 30, 2020, we retain the remaining 85.7% ownership interest following the closing of the Preferred Units Purchase Agreement. SoftBank and Toyota are our existing inv estors. SoftBank’s Preferred Units Beginning on July 2, 2026, SoftBank has the option to put to us all, but not less than all, of its initial investment in Preferred Units at a price equal to the number of SoftBank’s Preferred Units multiplied by the greater of (i) the original investment plus any accrued but unpaid amounts per unit and (ii) the fair value of the Preferred Units at the time of conversion (the “Put/Call Price”). As of December 31, 2019 and September 30, 2020, the SoftBank Preferred Units are classified as redeemable non-controlling interests in our condensed consolidated financial statements and reported at the Put/Call Price which is determined as of each balance sheet date. The fair value of SoftBank’s Preferred Units is determined based on a hybrid method with the option pricing model as the primary methodology. This method uses Level 3 fair value measurement inputs as well as an assumed equal probability of the occurrence of a liquidation or exit event. The significant unobservable inputs used in the fair value measurement include: volatility of 55%, time to liquidity of 4.0 years, and a discount for lack of marketability of 17%. A market approach was also used to corroborate the valuation derived from the hybrid method at issuance to evidence that the issuance price of the Preferred Units approximated their fair value. There were no fair value adjustments to SoftBank’s redeemable non-controlling interests during the three and nine months ended September 30, 2020. Toyota and DENSO’s Preferred Units As of December 31, 2019 and September 30, 2020, the Toyota and DENSO Preferred Units are classified in permanent equity as non-controlling interests as these units are not subject to any mandatory redemption rights or redemption rights that are outside our control . ATG Collaboration Agreement with Apparate, Toyota and DENSO In conjunction with the Preferred Unit Purchase Agreement discussed above, we entered into a three-year joint collaboration agreement among Toyota, DENSO, and Apparate to develop next-generation self-driving technology (the “ATG Collaboration Agreement”), which became effective as of the closing of the Preferred Unit Purchase Agreement in July 2019. Pursuant to the ATG Collaboration Agreement, we will receive six semi-annual installments up to an aggregate of $300 million during the term of the ATG Collaboration Agreement. During the three months ended September 30, 2019, we recognized $17 million as revenue under the ATG Collaboration Agreement. We recognized $25 million and $75 million as revenue during the three and nine months ended September 30, 2020, respectively. Freight Holding As of December 31, 2019 and September 30, 2020, we owned 89% of the issued and outstanding capital stock of our subsidiary Freight Holding, or 80% on a fully-diluted basis if all shares reserved for issuance under our Freight Holding employee incentive plan were issued and outstanding. Under the Freight Holding incentive plan, a total number of 99.8 million shares of Freight Holding are reserved and available for grant and issuance. As of December 31, 2019 and September 30, 2020, the minority stockholders ownership in Freight Holding is classified in mezzanine equity as redeemable non-controlling interest, because it is redeemable on an event that is not solely in our control. The Freight Holding non-controlling interest is not remeasured to fair value because it is currently not probable that the non-controlling interest will become redeemable. Cornershop: CS-Global

Business Combinations [Abstract]
Business Combination	Note 16 – Business Combinations Careem On March 26, 2019, we entered into an Asset Purchase Agreement with Careem. Pursuant to the Asset Purchase Agreement, we agreed to acquire substantially all of the assets and assume substantially all of the liabilities of Careem. On January 2, 2020, we completed the acquisition of substantially all of the assets of Careem. Dubai-based Careem was founded in 2012, and provides primarily ridesharing and to a lesser extent meal delivery, and payments services to millions of users in cities across the Middle East, North Africa, and Pakistan. The acquisition has been accounted for as a business combination and advances our strategy of having a leading ridesharing category position in every major region of the world in which we operate and effect cost and technology synergies for the rest of Uber’s Mobility business. As of September 30, 2020, ownership of Careem’s operations in Qatar and Morocco had not yet been transferred to us; however the results of operations and net assets were fully consolidated as variable interest entities. Refer to Note 14 – Variable Interest Entities (“VIEs”) for further information. The acquisition date fair value of the consideration transferred for Careem was $3.0 billion, which consisted of the following (in millions): Fair Value Cash paid on January 2, 2020 $ 1,326 Non-interest bearing unsecured convertible notes 1,634 Transaction costs paid on January 2, 2020 on behalf of Careem 39 Contingent cash consideration 1 Stock-based compensation awards attributable to pre-combination services 3 Total consideration $ 3,003 The fair value of the non-interest bearing unsecured convertible notes (the “Careem Notes”) was determined as a sum of the discounted cash flow (“DCF”) method (for the present value of the principal amount of the Careem Notes) and the Black-Scholes option pricing model (to value the conversion option). The significant unobservable inputs used in the fair value measurement include discount rates of 5.14% to 5.19% for the principal amount of the Careem Notes and for the conversion option an expected volatility of 42.1% to 44.1%, interest rates of 1.53% to 1.57%, and dividend yield of 0%. We will issue the Careem Notes in different tranches with $880 million of the principal amount of the Careem Notes issued as of January 2, 2020 and settled in cash on April 1, 2020. The remaining amount of the Careem Notes is recognized as a commitment to issue unsecured convertible notes at fair value in accrued and other current liabilities of $458 million and in other long-term liabilities of $296 million as of January 2, 2020. Each tranche of the Careem Notes is due and payable 90 days once issued. The holders of the Careem Notes may elect to convert the full outstanding principal balance to Class A common stock at a conversion price of $55 per sha re of Uber Technologies, Inc. at a ny time prior to maturity. The discount from the Careem Notes face value to fair value will be accreted through the respective repayment dates as interest expense. The amount of accretion for the three and nine months ended September 30, 2020 was not material. The purchase price allocation is based on a preliminary valuation and subject to revision as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed becomes available. The following table summarizes the preliminary fair value of assets acquired and liabilities assumed as of the date of acquisition (in millions): Fair Value Current assets $ 43 Goodwill 2,484 Intangible assets 540 Other long-term assets 77 Total assets acquired 3,144 Current liabilities (108) Deferred tax liability (14) Other long-term liabilities (19) Total liabilities assumed (141) Net assets acquired $ 3,003 The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill which is not deductible for tax purposes. Goodwill is primarily attributed to the assembled workforce of Careem and anticipated operational synergies. Goodwill was recorded in our Mobility segment. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are based on management’s estimates and assumptions at the time of acquisition. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition (in millions, except years): Fair Value Weighted Average Remaining Useful Life - Years Rider relationships $ 270 15 Captains network 40 1 Developed technology 110 4 Trade names 120 10 Total $ 540 Rider relationships represent the fair value of the underlying relationships with Careem riders. Captains network represents the fair value of the underlying network with Careem drivers (called “Captains”). Developed technology represents the fair value of Careem’s technology. Trade names relate to the “Careem” trade name, trademarks, and domain names. The overall weighted average useful life of the identified amortizable intangible assets acquired is ten years. The estimated fair value of the intangible assets acquired was determined by our management, which considered, among other factors, a valuation report prepared by an independent third-party valuation firm. We used a multi-period excess earnings method to estimate the fair value of the rider relationships. The significant unobservable input used in the fair value measurement of rider relationships is the riders attrition rate. We used the replacement cost method to estimate the fair value of the Captains network and the relief from royalty method to estimate the fair values of developed technology and trade names. Tangible net assets were valued at their respective carrying amounts as of the acquisition date, as we believe that these amounts approximate their current fair values. We believe the amounts of purchased intangible assets recorded above represent the fair values of, and approximate the amounts a market participant would pay for, these intangible assets as of January 2, 2020. The Asset Purchase Agreement provides for specific indemnities to us in relation to value added tax obligations and other tax reserves of certain jurisdictions which reflect potential tax liabilities. We recognized $64 million of indemnification assets on the same basis as the tax reserves at January 2, 2020, which is recorded as other assets and other liabilities as of September 30, 2020. Settlements of these tax reserves, if any, will be funded by the indemnification asset. Results of acquired operations were included in our condensed consolidated financial statements from the date of acquisition, January 2, 2020. For the three months ended September 30, 2020 and for the period from January 2, 2020 through September 30, 2020, the acquired operations contributed pre-tax losses of $32 million and $184 million, respectively. Revenues for the three months ended September 30, 2020 and for the period from January 2, 2020 through September 30, 2020 were not material. Pro forma results of operations for Careem have not been presented as the effect of this acquisition was not material to our financial statements. Cornershop In 2019, we agreed to purchase a controlling interest in Cornershop Cayman ("Cornershop"), operating an online grocery delivery platform primarily in Chile and Mexico. During 2019, we made an initial investment of $50 million (the “Initial Cornershop Investment”). The remaining investment was subject to antitrust approval of the countries where Cornershop operates. During the second quarter of 2020, we received regulatory approvals, except for Mexico. As a result, we and Cornershop amended the terms of the agreement in order for Uber to acquire Cornershop’s business operations, except for those in Mexico. Immediately prior to the transaction close, Cornershop was restructured such that the Mexico operations were held in Cornershop Technologies LLC and its wholly owned subsidiary (collectively referred to as “CS-Mexico”), while all of the remaining Cornershop operations were to be held in the newly created CS-Global entity. On July 6, 2020, we closed on a purchase agreement to acquire CS-Global, resulting in an Uber direct capital contribution of $200 million, which includes the Initial Cornershop Investment and notes receivable, to CS-Global and a payment of $179 million to tendering shareholders, paid in a combination of cash and Uber common stock. In exchange for the consideration transferred, we received 15,642,523 Preferred C Membership Interests in CS-Global, representing 55% of the outstanding membership interests. As a result, we obtained the controlling financial interest in CS-Global and accounted for the acquisition as a business combination. For additional information on the accounting treatment of the remaining non-controlling interest in CS-Global, refer to Note 15 – Non-Controlling Interests. Uber and CS-Global also entered into a put/call arrangement over the non-controlling interest in CS-Global, providing Uber the right and obligation to acquire the remaining interest from non-controlling interest holders, exercisable in 5 years if there is no IPO or liquidation event, at a future negotiated price. Concurrent with the CS-Global Transaction, Uber, Cornershop and CS-Global entered into a put/call agreement providing CS-Global with the right through the call option (and obligation through the put option held by Cornershop) to purchase all of the interests in CS-Mexico, contingent on the receipt of regulatory approval in Mexico (“CS-Mexico Put/Call”). Upon either the exercise of the call option (by CS-Global) or the put option (by Cornershop), CS-Global would acquire 100% of the outstanding equity interests in CS-Mexico. Uber would make a direct capital contribution to CS-Global and a payment to the tendering shareholder, totaling $94 million, in exchange for 55% outstanding equity interest in CS-Mexico. The CS-Mexico Put/Call was accounted for separately from the acquisition, and was included in other current asset on the condensed consolidated balance sheet as of September 30, 2020. The acquisition date fair value of the consideration transferred for CS-Global was $361 million, which consisted of the following (in millions): Fair Value Initial Cornershop Investment $ 50 Notes receivable 10 Cash paid 252 Tender offer paid in Uber common stock 67 Total consideration transferred 379 Less: CS-Mexico Put/Call (18) Total consideration $ 361 The following table summarizes the preliminary fair value of assets acquired and liabilities assumed as of the date of acquisition (in millions): Fair Value Current assets $ 204 Goodwill 370 Intangible assets 122 Other long-term assets 11 Total assets acquired 707 Current liabilities (34) Deferred tax liability (19) Other long-term liabilities (3) Total liabilities assumed (56) Less: Redeemable non-controlling interests (290) Net assets acquired $ 361 The excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill which is not deductible for tax purposes. Goodwill is primarily attributed to the anticipated operational synergies. Goodwill was recorded in our Delivery segment. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are preliminary and based on management’s estimates and assumptions at the time of acquisition. The fair value of the redeemable non-controlling interest of $290 million was estimated based on the non-controlling interest’s respective share of the CS-Global enterprise value. The purchase price allocation as of the date of the acquisition was based on a preliminary valuation and is subject to updating as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed becomes available. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition (in millions, except years): Fair Value Weighted Average Remaining Useful Life - Years Vendor relationship $ 20 15 Shopper relationship 1 1 Customer relationship 14 5 Developed technology 58 4 Trade names 29 5 Total $ 122 Vendor, shopper and customer relationships represent the fair value of the underlying relationships with Cornershop vendors (such as grocery stores and supermarkets), shoppers and end-users. Developed technology represents the fair value of the technologies and systems behind CS-Global’s grocery delivery application. Trade names relate to the “Cornershop” trade name, trademarks, and domain names. The overall weighted average useful life of the identified amortizable intangible assets acquired is six years. The estimated fair value of the intangible assets acquired was determined by our management, using a multi-period excess earnings method to estimate the fair value of the vendor relationship. The significant unobservable input used in the fair value measurement of vendor relationship is the vendor attrition rate as well as the estimated future revenue generated by the existing vendors. We used the replacement cost method to estimate the fair value of shopper and customer relationships. The assumptions used are shopper hiring and onboarding costs, and customer development costs, respectively. We used the relief from royalty method to estimate the fair values of developed technology and trade names. The significant input used in the fair value measurement of developed technology and trade names is the royalty rate that a market participant would charge for the use of such assets. Tangible net assets were valued at their respective carrying amounts as of the acquisition date, as we believe that these amounts approximate their current fair values. We believe the amounts of purchased intangible assets recorded above represent the fair values of, and approximate the amounts a market participant would pay for, these intangible assets as of July 6, 2020. Results of acquired operations were included in our condensed consolidated financial statements from the date of acquisition, July 6, 2020. For the period from July 6, 2020 through September 30, 2020, the acquired operations contributed an immaterial amount of revenue and pre-tax loss. Pro forma results of operations for Cornershop have not been presented as the effect of this acquisition was not material to our financial statements. Routematch On July 14, 2020 (the “Routematch Acquisition Date”), we acquired 100% of the equity of Routematch, a software company offering specialized software and solutions to transit agencies, serving customers in the United States and Australia. The acquisition is expected to accelerate our development in the transit space. The acquisition of Routematch was accounted for as a business combination. Total consideration transferred included $85 million in cash and $29 million in Uber shares (939,683 shares of our common stock) based on the closing market price of $30.93 per share on the Routematch Acquisition Date. The purchase price of $114 million was allocated to goodwill of $89 million and to certain identifiable intangible assets (comprised of customer relationships, developed technology and trademark) of $27 million. Goodwill represents the excess of purchase consideration over the fair value of net tangible and identifiable intangible assets acquired, which is not deductible for tax purposes. Goodwill is primarily attributed to the anticipated operational synergies and was recorded in our Mobility segment. Amortization of the identified amortizable intangible assets is calculated using the straight-line method. The overall weighted average useful life of the identified amortizable intangible assets acquired is eight years. The purchase price allocation as of the Routematch Acquisition Date was based on a preliminary valuation and is subject to updating as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed becomes available. Results of acquired operations were included in our condensed consolidated financial statements from the date of acquisition, July 14, 2020. For the period from July 14, 2020 through September 30, 2020, the acquired operations contributed an immaterial amount of revenue and pre-tax loss. Pro forma results of operations for Routematch have not been presented as the effect of this acquisition was not material to our financial statements. Pending Acquisition of Postmates On July 5, 2020, we entered into a definitive agreement to acquire Postmates Inc. (“Postmates”), an on-demand delivery platform in the United States. The aggregate consideration to be paid is approximately 84 million shares of our common stock, subject to certain adjustments, in exchange for 100% ownership interest in Postmates. The transaction is subject to the approval of Postmates stockholders, regulatory approval and other customary closing conditions, and is expected to close in the first quarter of 2021. We also agreed to provide interim financing to Postmates of up to $100 million in the first year from the signing of the definitive agreement and up to an additional $100 million after the first year. At September 30, 2020, the interim financing had not been funded to Postmates. We may be required to pay Postmates a termination fee of up to $146 million if the purchase agreement is terminated under certain circumstances. On October 9, 2020, Postmates drew on the $100 million interim financing commitment pursuant to the definitive agreement. Interest of 2.5% per annum is accrued from the date of borrowing to the earlier of the (i) closing date and (ii) termination date. The outstanding principal amount, together with the accrued interest, becomes due and payable in full in cash on the closing date or the termination date. The outstanding principal amount and accrued interest may be deducted from the purchase price at closing or from the termination fee, depending on the outcome of the pending acquisition.

Discontinued Operations and Disposal Groups [Abstract]
Divestitures	Note 17 – Divestitures Divestiture of LCR to Waydrive In January 2019, an agreement was executed with Waydrive Holdings Pte. Ltd. (“Waydrive”) to purchase the Lion City Rentals Pte. Ltd. (“LCR”) business, specifically 100% of the equity interests of LCR and its subsidiary LCRF Pte. Ltd. (“LCRF”). Fair value of consideration received included $310 million of cash for the assets and liabilities of LCR and LC RF and up to $33 million of contingent consideration receivable for certain VAT receivables and receivables from certain commercial counterparties. As of September 30, 2020, we collected substantially all of the c ontingent consideration receivable. The resulting gain on disposal was not material to us. The transaction closed on January 25, 2019. The LCR business was included within our Mobility segment. Divestiture of Uber Eats India to Zomato On January 21, 2020, we entered into a definitive agreement and completed the divestiture of Uber Eats India to Zomato in exchange for (i) CCPS Preferred Shares of Zomato convertible into ordinary shares representing, when converted, 9.99% of the total voting capital of Zomato and (ii) a non-interest bearing note receivable to be repaid over the course of four years for reimbursement by Zomato of goods and services tax. The estimated fair value of the consideration received included the investment valued at $171 million and the $35 million of reimbursement of goods and services tax receivable from Zomato. The fair value of the CCPS Preferred Shares was based primarily on the observed transaction price for a similar security issued to new investors in close proximity to the time of our transaction with Zomato. The transaction resulted in a gain on disposal of $154 million recognized in other income (expense), net in the condensed consolidated statement of operations during the first quarter of 2020. The income tax effect of the sale was not material. The divestiture of Uber Eats India did not represent a strategic shift that would have had a major effect on our operations and financial results, and therefore does not qualify for reporting as a discontinued operation for financial statement purposes. Divestiture of JUMP and Investment in Lime On May 7, 2020, we entered into a series of transactions and agreements with Lime to divest our JUMP business (the “JUMP Divestiture”). Neutron Holdings, Inc. (“Lime”) is incorporated in Delaware for the purpose of owning and operating a fleet of dockless e-bikes and e-scooters for short-term access use by consumers for personal transportation. We previously held Lime Series C preferred stock and fully vested warrants to purchase Lime Series C-1 preferred stock. Uber contributed hardware, equipment, intellectual property rights, technology, licensed technology, and permits of our JUMP business (collectively, “JUMP Assets”) in certain markets to Lime. JUMP Assets and previously held investments and warrants in Lime were exchanged for common stock (the “Lime Common Stock”), newly issued Lime Series 1-C preferred stock (“Lime 1-C Preferred Stock”) and fully vested warrants to purchase Lime Series 1-C Preferred Stock (“Lime 1-C Preferred Stock Warrants”). Lime Common Stock represents approximately 11% of fully-diluted (24% undiluted) ownership interest in Lime and Lime 1-C Preferred Stock and Lime 1-C Preferred Stock Warrants represent approximately 3% of fully-diluted (2% undiluted) ownership interest in Lime as of September 30, 2020. Concurrently, we contributed $85 million of cash to Lime in exchange for a secured note convertible into Lime Series 3 Preferred Stock (the “Lime Convertible Note”), which may be converted at any time at our election representing 20% initial ownership in Lime as converted on a fully-diluted basis. In addition, we entered into a call option agreement which gives us for a two-year period beginning May 7, 2022 the right to acquire all of the outstanding equity interests of Lime held by its shareholders at fair value on the date of exercise, subject to regulatory approval. We have one seat on Lime’s five-person board of directors. We also amended our preexisting commercial agreement with Lime. Our ownership in Lime is comprised of Lime Common Stock, Lime 1-C Preferred Stock, Lime 1-C Preferred Stock Warrants, and the Lime Convertible Note (collectively, the “2020 Lime Investments”) and represents approximately 32% on an as converted and fully-diluted basis as of September 30, 2020. The 2020 Lime Investments are accounted for under the fair value option. Refer to Note 3 – Investments and Fair Value Measurement for additional information. Lime was assessed under the VIE model and considered an unconsolidated VIE. Refer to Note 14 – Variable Interest Entities (“VIEs”) for additional information. The JUMP Divestiture did not represent a strategic shift that would cause a major effect on our operations and financial results, and therefore does not qualify for reporting as a discontinued operation for financial reporting purposes. The resulting loss on disposal was not material to us and was recorded in other income (expense), net, in the condensed consolidated statement of operations during the second quarter of 2020.

We exited the JUMP business and incurred costs related to site closures and asset impairments and write-offs. Restructuring activities during the three and nine months ended September 30, 2019 and three months ended September 30, 2020 were not material. The following table presents the total restructuring and related charges associated with our segments as well as corporate charges for the nine months ended September 30, 2020 (in millions): Mobility $ 73 Delivery 33 Freight 7 ATG and Other Technology Programs 59 All Other (1) 120 Total restructuring and related charges by segment 292 Corporate G&A and Platform R&D 84 Total restructuring and related charges $ 376 (1) Includes restructuring and related charges associated with the exit of the JUMP business, including severance and other termination benefits of $31 million, site closure costs of $24 million and other costs of $65 million.

As of September 30, 2020, the carrying values of the assets and liabilities of the European Freight Business were not material. Greenbriar Equity Group, L.P. Investment in Freight On October 1, 2020, we entered into a preferred stock purchase agreement with affiliates of Greenbriar Equity Group, L.P. (“Greenbriar”). Pursuant to the preferred stock purchase agreement, Greenbriar agreed to invest an aggregate of $500 million in Uber Freight Holding Corporation (“Freight Holding”), the holding company for our Uber Freight business, in exchange for Series A convertible preferred stock of Freight Holding collectively representing approximately a 15% ownership interest in Freight Holding on a fully diluted basis. The aggregate $500 million investment will occur over numerous closings, subject to customary closing conditions. On October 6, 2020, the initial closing occurred pursuant to the preferred stock purchase agreement and Greenbriar invested $250 million in Freight Holding in exchange for Series A convertible preferred stock of Freight Holding collectively representing approximately an 8% ownership interest in Freight Holding on a fully diluted basis. Pursuant to the preferred stock purchase agreement, Greenbriar will invest an additional $250 million over the next 24 months based upon funding requirements of the Uber Freight operations. We will maintain majority ownership of the issued and outstanding capital stock of Freight Holding following such additional investment. Joint Venture Agreement with SK Telecom In October 2020, we entered into a joint venture agreement with SK Telecom Co., LTD. (“SK Telecom”). Pursuant to this agreement, we and SK Telecom’s mobility business (“Mobility Company”), which will be spun out of SK Telecom prior to the closing of the joint venture, will form a joint venture (the “Business”) in South Korea, focused on the business of e-hailing of passenger transportation (including taxis and limousines). Uber has agreed to invest an aggregate of approximately $100 million in the Business. At transaction close, we will own a majority stake in the Business. Subject to certain conditions, we and the Mobility Company will have certain fair value put and call rights with respect to the minority interest in the Business held by Mobility Company. The transaction is subject to regulatory approval and other customary closing conditions, including the approval by SK Telecom’s stockholders of the spin-off of Mobility Company, and is expected to close in the first half of 2021. Redemption of 2023 Senior Notes On October 21, 2020, the net proceeds from the 2028 Senior Notes, along with cash on hand, were used to redeem all of our outstanding 2023 Senior Notes.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. The condensed consolidated balance sheet as of December 31, 2019 included herein was derived from the audited consolidated financial statements as of that date but does not include all of the information and notes required by GAAP for complete financial statements. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended December 31, 2019, included in our Annual Report on Form 10-K. In the opinion of management, these financial statements include all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, comprehensive loss, cash flows and the change in equity for the periods presented. There have been no changes to our significant accounting policies described in the Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 2, 2020 that have had a material impact on our condensed consolidated financial statements and related notes, except for an update reflecting the new accounting standard related to the measurement of credit losses on available-for-sale debt securities and disclosure of our policy related to restructuring and related charges.
Basis of Consolidation	Basis of ConsolidationOur condensed consolidated financial statements include the accounts of Uber Technologies, Inc. and entities consolidated under the variable interest and voting models. All intercompany balances and transactions have been eliminated. Refer to Note 14 – Variable Interest Entities (“VIEs”) for further information.
Use of Estimates	Use of Estimates The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions, which affect the reported amounts in the financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and other assumptions which management believes are reasonable under the circumstances. On an ongoing basis, management evaluates estimates, including, but not limited to: the incremental borrowing rate (“IBR”) applied in lease accounting; fair values of investments and other financial instruments (including the measurement of credit or impairment losses); useful lives of amortizable long-lived assets and intangible assets; fair value of acquired intangible assets and related impairment assessments; impairment of goodwill; stock-based compensation; income taxes and non-income tax reserves; certain deferred tax assets and tax liabilities; insurance reserves; and other contingent liabilities. These estimates are inherently subject to judgment and actual results could differ from those estimates. We considered the impacts of the COVID-19 pandemic on the assumptions and inputs (including market data) supporting certain of these estimates, assumptions and judgments, in particular, our
Certain Significant Risks and Uncertainties - COVID-19	Certain Significant Risks and Uncertainties - COVID-19 In March 2020, the World Health Organization declared the outbreak of COVID-19 a pandemic. COVID-19 has rapidly impacted market and economic conditions globally. In an attempt to limit the spread of the virus, various governmental restrictions have been implemented, including business activities and travel restrictions, and “shelter-at-home” orders, that have had an adverse impact on our business and operations by reducing, in particular, the global demand for Mobility offerings. In light of the evolving nature of COVID-19 and the uncertainty it has produced around the world, it is not possible to predict the COVID-19 pandemic’s cumulative and ultimate impact on our future business operations, results of operations, financial position, liquidity, and cash flows. The extent of the impact of the pandemic on our business and financial results will depend largely on future developments, including the duration of the spread of the outbreak both globally and within the United States, including whether there will be resurgences of COVID-19 in various regions, the impact on capital, foreign currencies exchange and financial markets, governmental or regulatory orders that impact our business and whether the impacts may result in permanent changes to our end-user’ behavior, all of which are highly uncertain and cannot be predicted.
Revenue Recognition	Revenue Recognition Mobility During the first quarter of 2020, we began charging end-users a fee for services in certain markets. In these transactions, we enter into a Master Services Agreements (“MSA”) with the end-user to use the platform for a fee. The combination of the MSA and the individual transaction request establishes enforceable rights and obligations for each transaction. We have determined that in these transactions, the end-user is our customer, in addition to the previously disclosed customers, and revenue from these contracts is also recognized under Accounting Standards Codification (“ASC”) 606. In these transactions, in addition to a performance obligation to Drivers, we also have one performance obligation to end-users, which is to connect end-users to Drivers in the marketplace. We recognize revenue when a trip is complete. We continue to present revenue on a net basis for these transactions, as we do not control the service provided by Drivers to end-users. We recognized total revenue of $61 million and $253 million associated with these fees charged to end-users for the three and nine months ended September 30, 2020, respectively. Delivery During the first quarter of 2020, we began charging a direct fee to end-users for delivery services in certain markets. In these transactions, we enter into an MSA with the end-user to use the platform for delivery services for a fee and separately subcontract with Delivery People to provide delivery services to end-users. The combination of the end-user MSA and the individual end-user transaction request establishes enforceable rights and obligations for each transaction. Our contract with end-users creates one performance obligation, which is to provide delivery services to end-users in these markets. We have determined that in these transactions, restaurants and end-users are our customers and revenue from these contracts shall be recognized separately for each under ASC 606. We recognize delivery service revenue associated with our performance obligation over the contract term, which represents our performance over the period of time the delivery is occurring. Our previously disclosed revenue recognition policy for contracts with Merchants remains unchanged. We present revenue on a gross basis for the delivery of meals, as we control the delivery service in these transactions and we are primarily responsible for delivery. Consistent with previous disclosures, we will continue to present revenue on a net basis for the sale of meals. We recognized revenue of $39 million and $77 million for the three and nine months ended September 30, 2020, respectively and cost of revenue, exclusive of depreciation and amortization of $119 million and $269 million for the three and nine months ended September 30, 2020, respectively for these delivery transactions. End-user Discounts and Promotions Any promotions utilized by an end-user in these Mobility and Delivery transactions where the end-user is a customer are accounted for as consideration payable to a customer, and recorded as a reduction of revenue, if we do not receive a distinct good or service or cannot reasonably estimate the fair value of the good or service received.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable represents uncollected fare payments from end-users for completed transactions where (i) the payment method is credit card and includes (a) end-user fare amounts not yet settled with payment service providers, and (b) end-user fare amounts settled by payment service providers but not yet remitted to us, or (ii) completed shipments where we invoice Freight Customers (“Shippers”) and payment has not been received. The timing of settlement of amounts due from these parties varies by region and by product. The portion of the fare receivable to be remitted to Drivers and Merchants is included in accrued and other current liabilities. Refer to Note 8 – Supplemental Financial Statement Information for amounts payable to Drivers and Merchants. Although we pre-authorize forms of payment to mitigate our exposure, we bear the cost of any accounts receivable losses. We record an allowance for doubtful accounts for credit losses for fare and invoiced amounts that may never settle or be collected, as well as for credit card chargebacks including fraudulent credit card transactions. We consider the allowance for doubtful accounts for fare amounts to be direct and incremental costs to revenue earned and, therefore, the costs are included as cost of revenue in the consolidated statements of operations. We estimate the allowance based on historical experience, estimated future payments and geographical trends, which are reviewed periodically and as needed, and amounts are written off when determined to be uncollectable. Allowance for Credit Losses on Available-for-sale Debt Securities We account for credit losses on available-for-sale debt securities in accordance with ASC 326, Financial Instruments - Credit Losses (“ASC 326”). We adopted ASC 326 on January 1, 2020, on a modified retrospective basis. Under ASC 326, at each reporting period, we evaluate our available-for-sale debt securities at the individual security level to determine whether there is a decline in the fair value below its amortized cost basis (an impairment). In circumstances where we intend to sell, or are more likely than not required to sell, the security before it recovers its amortized cost basis, the difference between fair value and amortized cost is recognized as a loss in the consolidated statement of operations, with a corresponding write-down of the security’s amortized cost. In circumstances where neither condition exists, we then evaluate whether a decline is due to credit-related factors. The factors considered in determining whether a credit loss exists can include the extent to which fair value is less than the amortized cost basis, changes in the credit quality of the underlying loan obligors, credit ratings actions, as well as other factors. To determine the portion of a decline in fair value that is credit-related, we compare the present value of the expected cash flows of the security discounted at the security’s effective interest rate to the amortized cost basis of the security. A credit-related impairment is limited to the difference between fair value and amortized cost, and recognized as an allowance for credit loss on the consolidated balance sheet with a corresponding adjustment to net income (loss). Any remaining decline in fair value that is non-credit related is recognized in other comprehensive income (loss), net of tax. Improvements in expected cash flows due to improvements in credit are recognized through reversal of the credit loss and corresponding reduction in the allowance for credit loss.
Restructuring and Related Charges	Restructuring and Related Charges Costs associated with management-approved restructuring activities, including reductions in headcount, exiting a market or consolidation of facilities are recognized when they are incurred and may include employee termination benefits, impairment of long-lived assets, impairment of operating lease right-of-use assets, contract termination costs and accelerated lease cost for right-of-use assets that ceased to be used. We record a liability for employee termination benefits either when it is probable that an employee is entitled to them and the amount of the benefits can be reasonably estimated or when management has communicated the termination plan to employees and all of the following conditions have been met: management, having the authority to approve the action, commits to a plan of termination; the plan identifies the number of employees to be terminated, their job classifications and their locations, and the expected completion date; the plan establishes the terms of the benefit arrangement in sufficient detail to enable employees to determine the type and amount of benefits they will receive if they are involuntarily terminated; and actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. We accrue for costs to terminate contracts other than a lease when we terminate the contract in accordance with the contract terms. Costs that will continue to be incurred for the remaining term of a contract that is not a lease, and provide no economic benefits to us are recognized at the cease-use date. Costs associated with lease contracts are accounted for under the leasing accounting guidance or under the long-lived assets accounting guidance. Restructuring and related charges are recognized as an operating expense within the condensed consolidated statement of operations and are classified based on our classification policy for each category of operating expense. Personnel costs are classified based on each employee’s classification, impairment of long-lived assets are recorded within general and administrative expenses, and lease costs, including impairments of right-of-use assets, are classified in the same expense line item where each lease’s rent expense was recognized.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” to require the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, reasonable and supportable forecasts. The standard also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. ASC 326 was subsequently amended by ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments - Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” We adopted the standard and related amendments effective January 1, 2020 on a modified retrospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement,” which modifies the disclosure requirements in ASC 820, “Fair Value Measurement” (“ASC 820”). We adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, “Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract,” which aligns the requirements for capitalizing implementation costs incurred in a cloud computing arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use-software. We adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In October 2018, the FASB issued ASU 2018-17, “Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities,” which amends the guidance for determining whether a decision-making fee is a variable interest and requires organizations to consider indirect interests held through related parties under common control on a proportional basis rather than as the equivalent of a direct interest in its entirety. We adopted the new standard effective January 1, 2020 on a retrospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which removes certain exceptions for performing intraperiod allocation, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance reduces complexity in certain areas, including franchise taxes that are partially based on income and accounting for tax law changes in interim periods. We early adopted the new standard effective January 1, 2020 on a prospective basis. The adoption of the new standard did not have a material impact on our condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting,” which provides optional expedients and exceptions to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued. The standard is effective upon issuance through December 31, 2022 and may be applied at the beginning of the interim period that includes March 12, 2020 or any date thereafter. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which reduces the number of models used to account for convertible instruments, amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives and modifies the diluted earnings per share calculations for convertible instruments. The standard is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2021. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. We are currently evaluating the impact of this accounting standard update on our consolidated financial statements.
Net Income (Loss) Per Share	Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period presented. Diluted net income (loss) per share is computed by giving effect to all potential weighted average dilutive common stock. The dilutive effect of outstanding awards and convertible securities is reflected in diluted net income (loss) per share by application of the treasury stock method.
