Segment reporting is the reporting of the operating segments of a company in its financial statement disclosures. It is required for public companies to provide information to investors and creditors about the financial results and position of a company's most important operating units. An operating segment engages in business activities to earn revenue and expenses, has discrete financial information available, and has its results regularly reviewed by management. Segment reporting rules require aggregating similar segments, and reporting segments that represent at least 10% of revenues, profits/losses, or assets. Additional segments may be reported to reach the threshold of comprising 75% of total company revenue.
