Definitions

What is internal control?

COSO defines internal control as a process, effected by an entity’s board of directors, management and other personnel. This process is designed to provide reasonable assurance regarding the achievement of objectives in effectiveness and efficiency of operations, reliability of financial reporting, and compliance with applicable laws and regulations.

  1. Internal control is a process. It is a means to an end, not an end in itself.
  2. Internal control is not merely documented by policy manuals and forms. Rather, it is put in by people at every level of an organization.
  3. Internal control can provide only reasonable assurance, not absolute assurance, to an entity’s management and board.
  4. Internal control is geared to the achievement of objectives in one or more separate but overlapping categories.
