The Company conducts business globally and is managed, operated and organized by major functional departments that operate on a consolidated basis. Each major functional leader reports directly to the Company's chief executive officer, who is the chief operating decision maker (“CODM”). The Company’s CODM views the business, allocates resources and assesses the performance of the Company primarily based on consolidated financial information for the entire business, accompanied by disaggregated information about net revenues by product and service and geographic region as presented below. As a result, the Company operates in one reportable operating segment, and all financial segment information can be found in the accompanying Consolidated Financial Statements.
