Internal Control vs. Internal Audit

Internal Control

Internal control, as defined by accounting and auditing, is a process for assuring of an organization’s objectives in operational effectiveness and efficiency, reliable financial reporting, and compliance with laws, regulations and policies. A broad concept, internal control involves everything that controls risks to an organization.

It is a means by which an organization’s resources are directed, monitored, and measured. It plays an important role in detecting and preventing fraud and protecting the organization’s resources, both physical (e.g., machinery and property) and intangible (e.g., reputation or intellectual property such as trademarks).

At the organizational level, internal control objectives relate to the reliability of financial reporting, timely feedback on the achievement of operational or strategic goals, and compliance with laws and regulations. At the specific transaction level, internal controls refers to the actions taken to achieve a specific objective (e.g., how to ensure the organization’s payments to third parties are for valid services rendered.) Internal control procedures reduce process variation, leading to more predictable outcomes. Internal control is a key element of the Foreign Corrupt Practices Act (FCPA) of 1977 and the Sarbanes–Oxley Act of 2002, which required improvements in internal control in United States public corporations. Internal controls within business entities are also referred to as operational controls. The main controls in place are sometimes referred to as “key financial controls” (KFCs).

Under the COSO Internal Control-Integrated Framework, a widely used framework in not only the United States but around the world, internal control is broadly defined as 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.

COSO defines internal control as having five components:

  • Control Environment-sets the tone for the organization, influencing the control consciousness of its people. It is the foundation for all other components of internal control.
  • Risk Assessment-the identification and analysis of relevant risks to the achievement of objectives, forming a basis for how the risks should be managed
  • Information and Communication-systems or processes that support the identification, capture, and exchange of information in a form and time frame that enable people to carry out their responsibilities
  • Control Activities-the policies and procedures that help ensure management directives are carried out.
  • Monitoring-processes used to assess the quality of internal control performance over time.

Types and examples of these controls could be:

  • Automated preventive control: Having firewalls, system backup features, etc.
  • Manual preventative control: Hiring security guards, identification verification procedures, etc.
  • Manual detective control: Carrying out audits, inspections, etc.
  • Manual corrective control: Disciplinary actions, refined policies, etc.
  • Automated detective control: Reconciling information from one system to another, etc.
  • Automated corrective control: Installing software patches, maintaining password secrecy, etc.

Components of Internal Control

Multiple components comprise the framework. The first thing to ensure that the companies’ controls work perfectly is an appropriate control environment. This is what sets the conscious levels, making everyone from top management to staff members follow and keep a check on the policies, procedures, principles, and technology deployed. In addition, it sets the values, commitment, policies, responsibilities, operating style, participation, structure, and overall tone of the company.

  • There are chances of misuse by a person of authority who is operating on internal control system.
  • Management decision to choose to cost effective control system may reduce the effectiveness of internal control system.
  • Objectives of internal control systems may be defeated by manipulation of management.
  • Since internal control system is involved in routine transactions, irregular transactions may be overlooked.

Internal Audit

Internal auditing is 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. Internal auditing might achieve this goal by providing insight and recommendations based on analyses and assessments of data and business processes. With commitment to integrity and accountability, internal auditing provides value to governing bodies and senior management as an objective source of independent advice. Professionals called internal auditors are employed by organizations to perform the internal auditing activity.

The scope of internal auditing within an organization may be broad and may involve topics such as an organization’s governance, risk management and management controls over: efficiency/effectiveness of operations (including safeguarding of assets), the reliability of financial and management reporting, and compliance with laws and regulations. Internal auditing may also involve conducting proactive fraud audits to identify potentially fraudulent acts; participating in fraud investigations under the direction of fraud investigation professionals and conducting post investigation fraud audits to identify control breakdowns and establish financial loss.

Internal auditors are not responsible for the execution of company activities; they advise management and the board of directors (or similar oversight body) regarding how to better execute their responsibilities. As a result of their broad scope of involvement, internal auditors may have a variety of higher educational and professional backgrounds.

The Institute of Internal Auditors (IIA) is the recognized international standard setting body for the internal audit profession and awards the Certified Internal Auditor designation internationally through rigorous written examination. Other designations are available in certain countries. In the United States the professional standards of the Institute of Internal Auditors have been codified in several states’ statutes pertaining to the practice of internal auditing in government (New York State, Texas, and Florida being three examples). There are also a number of other international standard setting bodies.
