GEOGRAPHIC AND CUSTOMER CONCENTRATION INFORMATION

The authoritative guidance on segment reporting and disclosure defines an operating segment as a component of an enterprise for 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. For the purposes of evaluating our reportable segments, our Chief Executive Officer is the chief operating decision maker.

We have one operating segment in which we design, manufacture and market advanced fabrication equipment for the semiconductor manufacturing industry. As our business is completely focused on one industry segment, the design, manufacture and marketing of advanced fabrication equipment to the semiconductor manufacturing industry, management believes that we have one reportable segment. Our net revenue and profits are generated from the sales of systems and services in this one segment.

The following table summarizes net revenue by geographic areas based on the installation locations of the systems and the location of services rendered (in thousands, except percentages):
