Building an Internal Control Framework with COSO

Companies often describe their controls in their own vocabulary — "we have approvals," "the finance manager checks everything." The problem comes when someone external has to judge whether those controls are adequate. Adequate against what? Without a recognized framework, the assessment becomes a matter of opinion, and opinion is exactly what governance is meant to remove.

The Committee of Sponsoring Organizations (COSO) Internal Control — Integrated Framework is the most widely adopted answer. It gives internal control a shared structure: five components, supported by a set of underlying principles, that together define what a sound control system looks like. Auditors know it, boards understand it, and regulators expect controls that can be mapped to it.

The five components

COSO organizes internal control into five components. They are not a menu — a control system is only as strong as its weakest one.

1. Control environment

The foundation. This is the tone, integrity, and structure that make control possible: the board's oversight, the organization's values, clear assignment of authority and responsibility, and a commitment to competence. Everything else rests on it. Sophisticated control activities sitting on a weak environment — where leaders bypass their own rules — provide little assurance.

2. Risk assessment

You cannot control what you have not identified. Risk assessment is the disciplined process of setting objectives, then identifying and analyzing what could stop you meeting them — including the risk of fraud. It is what keeps a control system pointed at the risks that actually matter to this business, rather than a generic checklist inherited from somewhere else.

3. Control activities

The actions that address the risks: approvals, authorizations, verifications, reconciliations, segregation of duties, and controls over the systems that process transactions. This is the component people picture when they hear "internal control," but on its own it is only one part — a well-designed control aimed at the wrong risk, in a weak environment, achieves little.

4. Information and communication

Controls depend on the right information reaching the right people in time to act. This component covers the quality of information used to run controls, and the channels — up to the board, down to the front line, and out to relevant external parties — through which control responsibilities and results are communicated. Where information is late, incomplete, or trapped in silos, controls fail quietly.

5. Monitoring activities

A control system is not set and forgotten. Monitoring — through ongoing checks built into operations and periodic separate evaluations, including internal audit — confirms that controls are still present and still working, and surfaces deficiencies so they can be corrected. Without it, a framework decays: controls lapse, and no one knows until an incident or an audit reveals it.

Design tells you a control should work. Monitoring tells you it still does. Boards need both.

Principles, not just components

Beneath the five components sits a set of underlying principles that make them concrete — for example, that the board demonstrates independence and oversight, that the organization holds people accountable, that it selects and develops control activities, and that it evaluates and communicates deficiencies. When you assess a control system against COSO, you are really asking whether these principles are present and functioning, component by component. That is also how an external reviewer will approach it.

Mapping to Saudi requirements

COSO is a framework, not a regulation — but it fits the Saudi environment well. Listed companies operate under the CMA's Corporate Governance Regulations, which expect a sound internal control system overseen by the board and its audit committee. Financial reporting follows IFRS as endorsed by SOCPA, and regulated sectors carry additional expectations from their supervisors. A COSO-aligned framework gives you a single, coherent structure that these requirements can be mapped onto — so you are not maintaining separate, disconnected answers for each regulator.

How to stand it up

Building the framework is less about documentation and more about sequence:

• Set objectives and assess risk first. Controls exist to protect objectives; identify those and the risks to them before designing anything.
• Design controls to the risks that matter — and no further. Over-controlling wastes effort and breeds workarounds.
• Assign a named owner to every key control. A control without an owner is a control that will lapse.
• Make controls produce evidence as they run, so monitoring and audit have something to test.
• Build monitoring in from the start, so deficiencies are found and fixed continuously, not annually.

A framework built this way does more than satisfy an auditor. It gives the board a defensible answer to the question every regulator eventually asks — how do you know your controls are adequate? — expressed in a language everyone at the table already understands.
