Segments
The Company is engaged in the operation of retail and wholesale stores and clubs, as well as eCommerce websites and mobile applications, located throughout the U.S., Africa, Canada, Central America, Chile, China, India and Mexico. The Company's operations are conducted in three reportable segments: Walmart U.S., Walmart International and Sam's Club. The Company defines its segments as those operations whose results the chief operating decision maker ("CODM") regularly reviews to analyze performance and allocate resources. The Company sells similar individual products and services in each of its segments. It is impractical to segregate and identify revenues for each of these individual products and services.
The Walmart U.S. segment includes the Company's mass merchandising concept in the U.S., as well as eCommerce, which includes omni-channel initiatives and certain other business offerings such as advertising services through Walmart Connect. The Walmart International segment consists of the Company's operations outside of the U.S., as well as eCommerce and omni-channel initiatives. The Sam's Club segment includes the warehouse membership clubs in the U.S., as well as samsclub.com and omni-channel initiatives. Corporate and support consists of corporate overhead and other items not allocated to any of the Company's segments.
The Company measures the results of its segments using, among other measures, each segment's net sales and operating income, which includes certain corporate overhead allocations. From time to time, the Company revises the measurement of each segment's operating income and other measures, including any corporate overhead allocations, as determined by the information regularly reviewed by its CODM.

Disaggregated Revenues
In the following tables, segment net sales are disaggregated by either merchandise category or by market. From time to time, the Company revises the assignment of net sales of a particular item to a merchandise category. When the assignment changes, previous period amounts are reclassified to be comparable to the current period's presentation.
In addition, net sales related to eCommerce are provided for each segment, which include omni-channel sales, where a customer initiates an order digitally and the order is fulfilled through a store or club.
