Business Segments, Customer Concentrations and Geographic Information

We operate as a single operating segment as managed by our Chief Executive Officer, who is considered our chief operating decision maker (“CODM”). The CODM bears the ultimate responsibility for, and is actively engaged in, the allocation of resources and the evaluation of our operating and financial results. We have concluded that we have a single operating segment based on the following:

•We are managed under a functionally-based organizational structure with the head of each function reporting directly to the CODM;

•We assess performance, including incentive compensation, based on consolidated operating performance and financial results;

•Our CODM allocates resources and makes other operating decisions based on specific customer business opportunities and

•We have an integrated process for the design, development and manufacturing services we provide to all of our customers. We also have centralized sales and administrative functions.
