Internal controls are processes designed to provide reasonable assurance of an organization's objectives regarding effectiveness, efficiency, reliable financial reporting, and compliance with laws and regulations. The key components of internal controls include control environment, risk assessment, control activities, information and communication, and monitoring activities. It is the responsibility of everyone in an organization to implement internal controls. Examples of internal control policies and procedures provided include segregation of duties, authorization of transactions, documentation of policies and procedures, and safeguarding of assets. Insufficient internal controls can lead to audit findings, mismanagement of funds, and inefficient use of resources.
