Segment Reporting [Abstract]

SEGMENT INFORMATION

SEGMENT INFORMATION

The Company reports segment information on the "management" approach which designates the internal reporting used by management for making decisions and assessing performance as the source of the Company's reportable segments. The Company has determined that its Chief Executive Officer is the Company's chief operating decision maker ("CODM") as he is responsible for reviewing and approving investments in the Company's technology platforms and manufacturing infrastructure.  The Company is organized in two reportable segments: Affymetrix Core and eBioscience.

Affymetrix Core is divided into four business units, with each business unit having its own strategic Marketing and Research and Development groups to better serve customers and respond quickly to the market needs.  Affymetrix Core manufacturing operations are based on platforms that are used to produce various Affymetrix products that serve multiple applications and markets and similar customer and economic characteristics. Additionally, the business units share certain research, development and common corporate services that provide capital, infrastructure and functional support. As such, the Company has concluded that the four business units represent one reportable operating segment. The following describes the four business units that form Affymetrix Core:

• Expression: This business unit markets the Company's GeneChip® gene expression products and services;

• Genetic Analysis and Clinical Applications: This business unit markets the Company's rapidly growing Axiom® genotyping product line, as well as products with clinical diagnostic and research applications including the CytoScan® and OncoScan products, as well as the QuantiGene ViewRNA in-situ hybridization platform for clinical translational research. In addition, the business unit is responsible for development and marketing of the Powered-by-Affymetrix (PbA) clinical partnering and licensing program which enables third-party diagnostic companies to access and develop DNA and RNA-based diagnostic tests on Affymetrix technology platforms. This business unit also markets the CytoScan Dx product, the recently FDA approved microarray system for post natal diagnostics of children with developmental delays and disorders;

• Life Science Reagents: This business unit sells reagents, enzymes, purification kits and biochemicals used by life science researchers and other tool provider businesses, including those developing and marketing Next Generation Sequencing products and molecular diagnostics; and

• Corporate: This business unit is comprised primarily of incidental revenue from royalty arrangements and field revenue from field-services provided to customers of the Company.

The eBioscience business unit operates with its own manufacturing, research and marketing groups. The eBioscience business unit does utilize certain Corporate functions such as finance, legal and human resources. This reportable segment specializes in the areas of flow cytometry reagents, immunoassays, microscopic imaging, other protein-based analyses, QuantiGene single and multiplex RNA solution assays (not including the QuantiGeneRNA View in-situ hybridization platform) and Procarta multiplex immunoassay product lines.

eBioscience began integrating the development and marketing of the QuantiGene (excluding the QuantiGene ViewRNA in-situ hybridization platform) and Procarta product lines during 2013 with full integration in 2014. These products were previously reported by the Expression Business Unit of the Affymetrix Core reportable segment.  Accordingly, segment information for prior periods has been restated to reflect these changes for purposes of comparability. 

The Company evaluates the performance of its reportable segments based on revenue and income (loss) from operations. Revenue is allocated to each business unit based on product codes. The eBioscience business is operated on a stand-alone basis.

The following table shows revenue and loss from operations by reportable operating segment for the three and six months ended June 30, 2014 and 2013 (in thousands):
