Information about Geographic Areas [Abstract]

Information about Geographic Areas

8. Information about Geographic Areas

Our chief operating decision-makers (i.e., Chief Executive Officer and certain direct reports) review financial information presented on a consolidated basis, accompanied by disaggregated information for purposes of allocating resources and evaluating financial performance. There are no segment managers who are held accountable by our chief operating decision-makers, or anyone else, for operations, operating results, or planning for levels or components below the consolidated unit level. Accordingly, we consider ourselves to be in a single reporting segment and operating unit structure.

Revenue by geography is based on the billing address of the customer. The following table sets forth revenue and long-lived assets by geographic area (in thousands):
