Note 12  Segment Information and Geographic Information The Company determines its 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, the Company renamed the Rides segment to Mobility and the Eats segment to Delivery. In addition, the Company entered into the JUMP Divestiture and reorganized certain immaterial offerings from Other Bets into Mobility. In the second quarter of 2020, Other Bets, which primarily included the Companys divested JUMP business, is no longer being reviewed by the CODM to allocate resources or evaluate performance. Therefore, Other Bets was no longer deemed an operating or reportable segment. The Company assessed these changes and determined it has four operating and reportable segments: Mobility, Delivery, Freight and, ATG and Other Technology Programs. Comparative periods were not recast as the impact on the Companys four operating and reportable segments was not material. Refer to Note 17  Divestitures for further information regarding the JUMP Divestiture. As of the second quarter of 2020, the Companys 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 the Companys 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 the Companys 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 the Companys reportable segments derive revenue, refer to Note 2  Revenue. The Companys segment operating performance measure is segment adjusted EBITDA. The CODM does not evaluate operating segments using asset information and, accordingly, the Company does 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 the Companys segments. Segment adjusted EBITDA also excludes non-cash items or items that management does not believe are reflective of the Companys ongoing core operations (as shown in the table below). The following table provides information about the Companys segments and a reconciliation of the total segment adjusted EBITDA to loss from operations (in millions): Three Months Ended June 30, Six Months Ended June 30, 2019 2020 2019 2020 Segment adjusted EBITDA: Mobility $ 506 $ 50 $ 698 $ 631 Delivery (286) (232) (595) (545) Freight (52) (49) (81) (113) ATG and Other Technology Programs (132) (91) (245) (199) Other Bets (70) (23) (112) (86) Total segment adjusted EBITDA (34) (345) (335) (312) Reconciling items: Corporate G&amp;A and Platform R&amp;D (1), (2) (622) (492) (1,190) (1,137) Depreciation and amortization (123) (129) (269) (257) Stock-based compensation expense (3,941) (131) (3,952) (408) Legal, tax, and regulatory reserve changes and settlements (380) (38) (380) (57) Driver appreciation award (299)  (299)  Payroll tax on IPO stock-based compensation (86)  (86)  Goodwill and asset impairments/loss on sale of assets  (16) (8) (209) Uber Eats India transaction and related costs    (10) JUMP transaction and related costs  (19)  (19) COVID-19 response initiatives  (48)  (72) Loss on lease terminations  (7)  (7) Restructuring and related charges  (382)  (382) Loss from operations $ (5,485) $ (1,607) $ (6,519) $ (2,870) (1) Excluding stock-based compensation expense.
