Segment Reporting [Abstract]

Segment Information, Operations By Geographic Area And Customer Concentration

Segment Information, Operations by Geographic Area and Customer Concentration

Operating segments are components of an enterprise about which separate financial information is available and is regularly evaluated by management, namely the Chief Operating Decision Maker (“CODM”) of an organization, in order to determine operating and resource allocation decisions. By this definition, the Company operates in three specific business units: retail, commercial, and service provider. The retail business unit consists of high performance, dependable and easy-to-use home networking, storage and digital media products to connect people with the Internet and their content and devices. The commercial business unit consists of business networking, storage and security solutions without the cost and complexity of Big IT. The service provider business unit consists of made-to-order and retail proven, whole home networking solutions sold to service providers for sale to their customers. Each business unit is managed by a Senior Vice President/General Manager. The Company believes this structure enables it to better focus its efforts on the Company’s core customer segments and allows it to be more nimble and opportunistic as a company overall.

In the second quarter of 2012, the CEO began temporarily serving as interim General Manager of the commercial business unit due to the previous general manager's departure from the Company. As of March 31, 2013, the CEO continues to serve as interim general manager until a replacement is established.

The results of the reportable segments are derived directly from the Company’s management reporting system. The results are based on the Company’s method of internal reporting and are not necessarily in conformity with accounting principles generally accepted in the United States. Management measures the performance of each segment based on several metrics, including contribution income. Segment contribution income includes all product line segment revenues less the related cost of sales, research and development and sales and marketing costs. Contribution income is used, in part, to evaluate the performance of, and allocate resources to, each of the segments. Certain operating expenses are not allocated to segments because they are separately managed at the corporate level. These unallocated indirect costs include corporate costs, such as corporate research and development, general and administrative costs, stock-based compensation expenses, amortization of intangibles, acquisition-related integration costs, restructuring costs, litigation reserves and interest and other income (expense), net. The Company does not evaluate operating segments using discrete asset information.

Financial information for each reportable segment and a reconciliation of segment contribution income to income before income taxes is as follows (in thousands, except percentage data):
