The COSO Internal Control Framework

Overview of COSO

The Committee of Sponsoring Organizations of the Treadway Commission (COSO) developed the most widely used framework for designing and evaluating internal control systems. The COSO Internal Control Framework forms the basis for understanding internal control in auditing.

• Provides a common framework for evaluating internal control.
• Used by management, auditors, regulators, and organizations worldwide.
• Supports reliable financial reporting and effective governance.

Internal control is a process—not a single policy or procedure.
