Operating segment

Under international financial reporting standards, an operating segment is a component of an entity that is a profit center, that has discrete financial information available, and whose results are reviewed regularly by the entity's chief operating decision maker for purposes of performance assessment and resource allocation. An operating segment generally has a segment manager who is accountable to the chief operating decision maker for the results of the segment.

An entity's corporate headquarters is not considered an operating segment, nor are an entity's post-employment benefit plans.
