Demystifying GRC: Key Terms Explained

The world of Governance, Risk, and Compliance (GRC) is full of acronyms, frameworks, and technical terms. Whether you're a compliance officer, finance leader, or simply someone looking to strengthen your organization’s understanding of risk and regulation, having a clear grasp of the basics is essential.

At Impero, we maintain a detailed GRC glossary. Below, we’ve expanded on some of the most important terms, explaining what they mean and why they matter for your business.

1. Governance, Risk, and Compliance (GRC)

What it is:
GRC is the collective approach organizations use to align strategy with governance, manage risks, and ensure compliance with regulations and internal policies. It combines:

• Governance: Setting direction, making decisions, and ensuring accountability
• Risk: Identifying and addressing threats to achieving objectives
• Compliance: Meeting external legal requirements and internal standards

Why it’s important:
An integrated GRC strategy prevents silos, improves decision-making, and helps organizations operate more efficiently—while building trust with stakeholders.

2. COSO Framework

What it is:
Developed by the Committee of Sponsoring Organizations of the Treadway Commission, the COSO Framework is a widely adopted model for designing and evaluating internal control systems. It defines five components:

• Control Environment
• Risk Assessment
• Control Activities
• Information & Communication
• Monitoring Activities

Why it’s important:
COSO provides a structured way to strengthen governance and risk management. It’s recognized by regulators and auditors, and often used to demonstrate compliance with laws such as SOX.

3. Risk Management

What it is:
Risk management is the process of identifying, assessing, and addressing potential risks that could impact business objectives—covering strategic, operational, financial, and compliance risks.

Why it’s important:
A sound risk management process enables informed decision-making—deciding which risks to avoid, mitigate, transfer, or accept—while keeping the business resilient and agile.

4. Internal Control System (ICS)

What it is:
An ICS is a framework of policies, procedures, and activities that ensure effective operations, reliable reporting, and compliance with laws and regulations. It includes:

• Preventive controls (e.g., approval processes)
• Detective controls (e.g., audits, reconciliations)

Why it’s important:
ICS helps prevent fraud, errors, and inefficiencies. It’s a cornerstone of compliance with frameworks like COSO and SOX and builds confidence among stakeholders.

5. Risk Control Matrix (RCM)

What it is:
An RCM links identified risks to the controls in place to mitigate them. It typically includes:

• Risk descriptions
• Control objectives
• Control activities
• Testing methods

Why it’s important:
An RCM provides visibility into how risks are managed. It streamlines audit processes by mapping risks to controls, ensuring critical threats are addressed.

6. Sarbanes–Oxley (SOX)

What it is:
The Sarbanes–Oxley Act of 2002 is U.S. legislation enacted after scandals like Enron and WorldCom. It requires public companies to:

• Implement strict internal controls
• Ensure accurate financial reporting
• Establish clear management accountability

Why it’s important:
SOX reshaped corporate governance in the U.S., setting high standards for accountability and transparency. Non-compliance can result in severe penalties and reputational harm.

7. UK Corporate Governance Code

What it is:
This Code outlines principles for how companies listed on the London Stock Exchange should be governed. It covers:

• Board effectiveness
• Accountability
• Executive pay
• Shareholder relations

Example: Provision 29 requires boards to monitor and assess risk management and internal control systems.

Why it’s important:
The Code promotes transparency and fairness in corporate governance. While designed for UK-listed companies, it's widely referenced as a global best practice.

8. Tax Compliance Management System (TCMS)

What it is:
A TCMS ensures companies identify, document, and fulfill tax obligations. It includes policies, processes, and controls for:

• Accurate tax reporting
• Risk management
• Compliance documentation

Why it’s important:
As tax compliance becomes more complex globally, a TCMS reduces the risk of errors, penalties, and reputational damage. It signals diligence to regulators and builds stakeholder trust.

9. Environmental, Social, and Governance (ESG)

What it is:
ESG refers to the three key non-financial factors used to measure sustainability and societal impact:

• Environmental: Carbon footprint, waste management, climate impact
• Social: Diversity, human rights, employee welfare
• Governance: Ethical practices, board accountability, transparency

Why it’s important:
Strong ESG performance is vital to investors, regulators, and consumers. It enhances reputation, attracts capital, and aligns with emerging reporting standards.
