Reportable Segments |
Reportable Segments | 16. Reportable Segments ​ The Company manages its operations under three reportable segments according to their geographic regions and business activities. The Americas segment provides planning, consulting, architectural and engineering design services, and construction management services to public and private clients in the United States, Canada, and Latin America, while the International segment provides similar professional services to public and private clients in Europe, the Middle East, India, Africa, and the Asia-Australia-Pacific regions. The Company’s AECOM Capital (ACAP) segment primarily invests in and develops real estate projects. ​ Although the services provided are similar, these reportable segments are organized by the differing specialized needs of the respective clients, and how the Company manages its business. The Company has aggregated operating segments into its Americas and International reportable segments based on their similar characteristics, including similar long term financial performance, the nature of services provided, internal processes for delivering those services, and types of customers. ​ The following tables set forth summarized financial information concerning the Company’s reportable segments: ​
