Segments

Our chief operating decision maker ("CODM") is our Chief Executive Officer. Our business is organized into two reportable segments: Domestic (which is comprised of all states, districts and territories of the U.S.) and International (which is comprised of all operations in Canada and Mexico). Our CODM has ultimate responsibility for enterprise decisions. Our CODM determines, in particular, resource allocation for, and monitors the performance of, the consolidated enterprise, the Domestic segment and the International segment. The Domestic segment managers and International segment managers have responsibility for operating decisions, allocating resources and assessing performance within their respective segments. Our CODM relies on internal management reporting that analyzes enterprise results to the net earnings level and segment results to the operating income level.

We aggregate our Canada and Mexico businesses into one International operating segment. Our Domestic and International operating segments also represent our reportable segments. The accounting policies of the segments are the same.
