You may have heard the term "internal control(s)," but what exactly is it? Evaluating internal controls is one of internal auditing's primary responsibilities.
The Institute of Internal Auditors (IIA) defines control, the control environment, and control processes as follows:
A control is any action taken by management, the board, and other parties to manage risk and increase the likelihood that established objectives and goals will be achieved. Management plans, organizes, and directs the performance of sufficient actions to provide reasonable assurance that objectives and goals will be achieved.
The control environment is the attitude and actions of the board and management regarding the importance of control within the organization. The control environment provides the discipline and structure for the achievement of the primary objectives of the system of internal control. The control environment includes the following elements:
Control processes are the policies, procedures (both manual and automated), and activities that are part of a control framework, designed and operated to ensure that risks are contained within the level that an organization is willing to accept. Risk management is a process to identify, assess, manage, and control potential events or situations to provide reasonable assurance regarding the achievement of the organization's objectives.
A broadly accepted definition of internal control comes from a report released in 1992 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO)1 entitled The Internal Control-Integrated Framework (COSO Report) as follows:
Internal control is a process, effected by an entity's board of directors, management and other personnel, designed to provide reasonable assurance regarding the achievement of objectives relating to operations, reporting, and compliance.
This may sound technical, so what does it mean in plain terms? Let's think of how each of us has developed what we can call our own "personal internal control system." Consider the following:
When you came to work today, did you lock the doors to your house? If you did, that’s your own “internal control” to safeguard the assets you own.
Do you keep the PIN number for your ATM card in a safe place? (i.e., away from the card itself.) If you do, that’s an internal control the bank recommends to protect your funds from being stolen.
Do you balance your bank statements each month? (You really should, you know.) If you do, then you are ensuring the accuracy of the transactions entered on the account statement.
Do you plan the shortest possible route to complete errands? If you do, then you are promoting operational efficiency.
Do you file annual income tax returns? If you do, then you are in compliance with federal and state tax regulations.
Key points about internal control include:
In the California State University (CSU) environment, internal controls serve the following purposes:
Generally, controls are of two types:
Preventative Controls: Designed to discourage errors or prevent irregularities from occurring. They are proactive controls that help prevent a loss. Examples: Separation of duties, proper authorization, adequate documentation, and physical control over assets.
Detective Controls: Designed to find errors or irregularities after they have occurred. Examples: Reviews, analyses, variance analyses, reconciliations, physical inventories, and audits.
The COSO Report further defines five interrelated components of internal control that must be present and functioning and operating together in order to conclude that internal control relating to an operation’s objective is effective:
In May 2013, COSO released an updated version of its Internal Control-Integrated Framework (Framework). The 1992 COSO Report conceptually introduced 17 relevant principles associated with the five components of internal control, which enable effective operation of the five components and the overall system of internal control. But these principles were implicit in the narrative. The 2013 Framework explicitly articulates the 17 principles as follows:
The auditors, right? Wrong! Everyone plays a part in the CSU's internal control system. Ultimately, it is CSU management's responsibility to ensure that controls are in place. That responsibility is delegated to each area of operation, which must ensure that internal controls are established, properly documented, and maintained. Every employee has some responsibility for making this internal control system function. Therefore, all CSU employees need to be aware of the concept and purpose of internal controls. Internal audit's role is to assist management in their oversight and operating responsibilities through independent audits and consultations designed to evaluate and promote the systems of internal control.
The IIA defines internal auditing as an independent, objective assurance and consulting activity designed to add value and improve an organization's operations. It helps an organization accomplish its objectives by bringing a systematic, disciplined approach to evaluate and improve the effectiveness of risk management, control, and governance processes.
The internal audit activity evaluates the adequacy and effectiveness of controls encompassing the organization's governance, operations, and information systems. Internal audit reviews include the reliability and integrity of financial and operational information, effectiveness and efficiency of operations and programs, safeguarding of assets, and compliance with laws, regulations, policies, procedures, and contracts. These reviews also ascertain the extent to which operating and program goals and objectives have been established and conform to those of the organization, as well as the extent to which results are consistent with established goals and objectives and whether operations and programs are being implemented or performed as intended.
