Segment Reporting [Abstract]

Segment Reporting

Segment Reporting

Our branded agency networks operate in the advertising, marketing and corporate communications services industry, and are organized into agency networks, virtual client networks, regional reporting units and operating groups or practice areas. Our networks, virtual client networks and agencies increasingly share clients and provide clients with integrated services. The main economic components of each agency are employee compensation and related costs and direct service costs and occupancy and other costs which include rent and occupancy costs, technology costs and other overhead expenses. Therefore, given these similarities, we aggregate our operating segments, which are our agency networks, into one reporting segment. In June 2021, we combined certain practice areas into a new reporting unit that primarily comprises the Omnicom Public Relations Group and assigned a segment manager to that reporting unit. As a result, the number of operating segments increased from five to six.

The agency networks' regional reporting units comprise three principal regions: the Americas, EMEA and Asia-Pacific. The regional reporting units monitor the performance and are responsible for the agencies in their region. Agencies within the regional reporting units serve similar clients in similar industries and in many cases the same clients and have similar economic characteristics.
