The Committee of Sponsoring Organizations of the Treadway Commission (COSO) was formed initially to enable the National Commission on Fraudulent Financial Reporting. It was founded by five significant professional associations: The American Accounting Association (AAA), the American Institute of Certified Public Accountants (AICPA), Financial Executives International (FEI), the Institute of Internal Auditors (IIA), and the Institute of Management Accountants (IMA) Organizations seeking to find that the COSO internal control framework offers an approach to Enterprise Risk Management (ERM) sensitive to variability from one organization to the next.

The COSO framework provides an applied risk management approach to internal controls. Applicable to both external financial reporting and internal control activities, the COSO framework focuses on the interrelationships between stakeholders and processes.

What is the purpose of the COSO?

Centralizing on adequate internal controls, COSO aids companies in meeting Sarbanes-Oxley (SOX) requirements. Revised in 2013, it continually updates guidance, expanding to include Enterprise Risk Management (ERM) and sustainability reporting.

The COSO framework, originating from a private-sector initiative involving organizations like the AICPA, IMA, AAA, IIA, and FEI, emphasizes fostering an effective internal control system. Its core aim is to facilitate fraud deterrence by establishing a robust control environment and control activities.

Aligned with the board of directors oversight and senior management decision-making, COSO ensures adherence to ethical values and achieving objectives. It aids in crafting an organizational structure that aligns with financial reporting requirements, particularly for public companies.

The framework’s updates reflect a commitment to address contemporary financial statement integrity and risk assessment challenges, meeting the directives of modern financial reporting regulations like SOX. Additionally, it serves as a guide for internal audit processes and separate evaluations, ensuring COSO compliance with evolving certifications and internal control standards.

What are the five principles of COSO?

The Committee of Sponsoring Organizations of the Treadway Commission (COSO) lays the foundation for effective internal controls through five fundamental pillars. Each pillar encapsulates essential components for robust risk management and compliance within organizations. Let’s delve into these key principles:

Control Environment

Establishing a robust control culture from top management down, emphasizing integrity, independence, structured responsibilities, capable personnel, and accountability.

Risk Assessment

Guiding periodic risk assessments to identify, evaluate, and treat risks, explicitly considering fraud risks and anticipating changes affecting internal controls.

Control Activities

Implementing processes and policies that address risks, specifically over technology, ensuring appropriate control mechanisms are in place.

Information and Communication

Emphasizing quality data usage and consistent internal and external communication, aligning with control objectives and stakeholder demands.

Monitoring Activities

Regularly evaluate and report on the effectiveness of the internal controls system, reporting deficiencies on time to accountable parties.

Key Steps to Implementing the COSO Framework


Compliance management software often facilitates understanding the framework’s objectives and aligning it strategically within the organization. This step ensures synchronization with business objectives and establishes an effective internal control system.

Evaluation and Documentation

Assessing the maturity of internal controls, documenting existing processes, and identifying gaps for remediation, ensuring reasonable assurance in achieving internal control objectives.


Addressing identified gaps or deficiencies in the control program through planned mitigation activities, aligning with the Committee of Sponsoring Organizations of the Treadway Commission guidelines for an effective control environment.

Testing and Reporting

Evaluating the design and effectiveness of controls, accompanied by regular reporting to management on the internal controls program, emphasizing evaluations to refine risk assessment and ensure compliance with financial reporting standards.
