Segment Information | 13. Segment Information Reportable Segments The Company identifies its reportable segments based on its operating and reporting structure. The Company operates in three reportable segments: Laser Products, Precision Motion and Technologies and Semiconductor Systems. The Company’s chief operating decision maker is the Chief Executive Officer. As a result of the Chief Executive Officer’s reassessment of the Company’s operating and reporting structure, the Company realigned the structure of its internal organization in April 2011 into three distinct operating divisions, each reporting to a separate divisional manager. Consequently, the realignment caused the composition of the Company’s reportable segments to change from prior years, with the exception of the Semiconductor Systems segment. The new structure allows the Company to prioritize its investments, align its resources to meet the demands of the markets the Company serves, optimize business performance and maximize opportunities for collaboration and synergy within each segment. The Company’s reportable segments have been identified based on commonality of end markets, customers and technologies amongst the Company’s individual product lines, which is consistent with the Company’s operating structure and associated management structure. The Company’s reportable segment financial information has been restated to reflect the updated reportable segment structure for all periods presented. The Company’s reportable segments and their principal activities are described below. Laser Products The Laser Products segment designs, manufactures and markets photonics-based solutions, consisting of lasers and laser-based systems, to customers worldwide. The segment serves highly demanding photonics-based applications such as cutting, welding, marking, engraving, micro-machining, and scientific research. The segment sells these products both directly utilizing the highly technical sales force and indirectly through resellers and distributors. Precision Motion and Technologies The Precision Motion and Technologies segment designs, manufactures and markets air bearing spindles, encoders, thermal printers, laser scanning devices, and light and color measurement systems to customers worldwide. The vast majority of the segment’s product offerings in precision motion and optical control technologies are sold to original equipment manufacturers (“OEM’s”). The segment sells these products both directly utilizing a highly technical sales force and indirectly through resellers and distributors. Semiconductor Systems Our Semiconductor Systems segment designs, develops and sells laser based production systems for semiconductor, microelectronics and electronics manufacturing. The segment offers a full spectrum of production systems, featuring high precision laser and motion technology, to process semiconductor wafers, LCD panels and microelectronic components. Semiconductor Systems’ solutions address a wide range of applications in a variety of end markets, including industrial, scientific, consumer electronics, medical, and aerospace. Today, the segment supplies leading global foundries, integrated design manufacturers and component manufacturers. Reportable Segment Financial Information
