Business Segments, Customer Concentrations and Geographic Information

•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.
