14.Segment and Disaggregated Revenue Information

We conduct business globally. Our chief operating decision maker (Chief Executive Officer) reviews financial information presented on a consolidated basis accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity, software and services to manage and secure mobile devices, applications and content, and there are no segment managers who are held accountable for operations, operating results and plans for levels, components or types of products or services below the consolidated unit level. Accordingly, we are considered to be in a single reportable segment and operating unit structure.
