Segment Reporting
Note 12 – Segment Reporting

We manage our business activities on a consolidated basis and operate as a single operating segment: Wireless. We primarily derive our revenue in the United States by providing wireless communications services to customers using our wireless networks and selling devices that provide customers access to our wireless networks. The accounting policies of the Wireless segment are the same as those described in Note 1 – Summary of Significant Accounting Policies.

Our CODM is our President and Chief Executive Officer, G. Michael Sievert. The CODM uses Net income, as reported on our Consolidated Statements of Comprehensive Income, in evaluating performance of the Wireless segment and determining how to allocate resources of the Company as a whole, including investing in our networks and customers, stockholder return programs and acquisition strategy. The CODM does not review assets in evaluating the results of the Wireless segment, and therefore, such information is not presented.
The following table provides the operating financial results of our Wireless segment:
