Segment Information | 13. Segment Information The Company’s chief operating decision maker, together with other senior management personnel, currently focus their review of consolidated financial information and the allocation of resources based on reporting of operating results, including revenues and operating income, for the geographic regions of the Americas, Europe/Middle East/Africa (“EMEA”) and Asia/Pacific. The Company’s products are sold and supported through distribution networks covering these three geographic regions, with each distribution network having its own sales force. The Company supplements its distribution networks with independent reseller and/or distributor arrangements. As such, the Company has concluded that its three geographic regions are its operating segments. The Company’s chief operating decision maker reviews financial information presented on a consolidated basis, accompanied by disaggregated information about revenues and operating income (loss) by geographical region. The Company allocated segment support expenses such as global product delivery and development, global customer operations and global product management based upon percentage of revenue per segment. Corporate overhead costs are allocated as a percentage of the headcount by segment. The following is selected segment financial data for the periods indicated (in thousands):
