Internal Controls: Mechanisms, Rules, and Procedures

LESSON four point one INTERNAL CONTROLS

Internal controls are the mechanisms, rules, and procedures implemented by a company to ensure the integrity of financial and accounting information, promote accountability and prevent fraud.

Besides complying with laws and regulations, and preventing employees from stealing assets or committing fraud, internal controls can help improve operational efficiency by improving the accuracy and timeliness of financial reporting.

Understanding Internal Controls

Internal controls have become a key business function for every U.S. company since the accounting scandals in the early two thousands. In their wake, the Sarbanes-Oxley Act of two thousand two was enacted to protect investors from fraudulent accounting activities and improve the accuracy and reliability of corporate disclosures. This has had a profound effect on corporate governance, by making managers responsible for financial reporting and creating an audit trail. Managers found guilty of not properly establishing and managing internal controls face serious criminal penalties.

The auditor's opinion that accompanies financial statements is based on an audit of the procedures and records used to produce them. As part of an audit, external auditors will test a company's accounting processes and internal controls and provide an opinion as to their effectiveness.

Internal audits evaluate a company's internal controls, including its corporate governance and accounting processes. They ensure compliance with laws and regulations and accurate and timely financial reporting and data collection, as well as helping to maintain operational efficiency by identifying problems and correcting lapses before they are discovered in an external audit. Internal audits play a critical role in a company's operations and corporate governance, now that the Sarbanes-Oxley Act of two thousand two has made managers legally responsible for the accuracy of its financial statements.

No two systems of internal controls are identical, but many core philosophies regarding financial integrity and accounting practices have become standard management practices. While internal controls can be expensive, properly implemented internal controls can help streamline operations and increase operational efficiency, in addition to preventing fraud.

Regardless of the policies and procedures established by an organization, only reasonable assurance may be provided that internal controls are effective and financial information is correct. The effectiveness of internal controls is limited by human judgment. A business will often give high-level personnel the ability to override internal controls for operational efficiency reasons, and internal controls can be circumvented through collusion.
