Segment Information
NOTE 4. SEGMENT INFORMATION
 
Our segments are comprised of strategic business units or other operations that offer products and services to different customer segments over various technology platforms and/or in different geographies that are managed accordingly. We have three reportable segments: Advanced Connectivity, Legacy and Latin America.
 
Our chief operating decision maker (CODM) is our Chairman of the Board, Chief Executive Officer and President. Our CODM uses operating income to evaluate performance and allocate resources, including capital allocations, when managing the business. Our CODM manages operations through the review of actual and forecasted “Operations and Support Expenses” information, which are primarily comprised of costs for wireless devices, network access, rents, leases, sales support, customer provisioning and commissions. Operating costs and depreciation of our shared network, including copper-based assets prior to decommissioning, are managed in our Advanced Connectivity segment. Our Legacy and Latin America segments are primarily evaluated on a direct cost basis. Our CODM does not review disaggregated assets on a segment basis, therefore, that information is not presented.

The Advanced Connectivity segment provides domestic 5G and fiber-based wireless, internet and other advanced connectivity services to consumer and business customers.

The Legacy segment provides domestic legacy voice and data services to consumer and business customers over our copper-based network. Legacy segment results include revenues derived from copper-based services and direct operating costs.

The Latin America segment provides wireless service and equipment in Mexico.

Corporate and Other reconciles our segment results to consolidated operating income and income from continuing operations before income taxes and includes parent support costs, securitization fees, operations from business no longer integral to operations and significant items for which the segments are not being evaluated. Significant items typically include costs associated with the merger and integration of acquired or divested businesses, including amortization of intangible assets, legal and other items that cover historical periods, novel theories of liability and are separate and distinct from normal recurring costs, benefit-related gains and losses, employee separation charges associated with voluntary and/or strategic offers, asset impairments and abandonments and restructuring.
 
“Total other income (expense)” consists of “Interest expense,” “Other income (expense) – net” and “Equity in net income (loss) of affiliates” and is managed only on a total company basis and are, accordingly, reflected only in consolidated results.
