Segment Reporting [Abstract]

Segment Reporting

Our five 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 five agency networks, into one reporting segment.

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.

The Americas comprises North America, which includes the United States, Canada and Puerto Rico, and Latin America, which includes South America and Mexico. EMEA comprises Europe, the Middle East and Africa. Asia-Pacific comprises Australia, China, India, Japan, Korea, New Zealand, Singapore and other Asian countries. Revenue in the United States for the three and six months ended June 30, 2019 was $2,005.2 million and $3,889.4 million, respectively, and for the three and six months ended June 30, 2018 was $1,990.8 million and $3,871.9 million, respectively.

The increase in long-lived assets and goodwill from 2018 to 2019 is primarily the result of recording the operating lease right-of-use assets upon the adoption of ASC 842 on January 1, 2019 (see Note 1) partially offset by the impact of changes in the value of foreign currencies against the U.S. Dollar during the periods.
