14. Segment and Geographic Information

We have a single operating segment. This operating segment is comprised of semiconductor products used primarily in power-related applications. While we have separate legal subsidiaries with discrete financial information, we have one chief operating decision maker with highly integrated businesses. Our net revenues by major geographic area (based on destination) were as follows (in thousands):
