Segment and Geographic Information

11. Segment and Geographic Information

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, in deciding how to allocate resources and in assessing performance. The Company’s chief operating decision maker is its chief executive officer (the “CEO”). The CEO reviews financial information presented on a consolidated basis, along with information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. Discrete information on a geographic basis, except for revenue, is not provided below the consolidated level to the CEO. The Company has concluded that it operates in one segment and has provided the required enterprise-wide disclosures.

Revenue by geographic area is based on the location of the end-user carrier. The following tables present revenue and long-lived assets, net, by geographic area (in thousands):
