Auditing Evidence

Companies periodically have their financial figures reviewed by an outside party (See: Auditor). This process is called an audit. The information used to conduct the audit - the records and other documents - are known as the "auditing evidence."
The type of auditing evidence needed is laid out in several sources. Some items are detailed in relevant legislation. This is especially true with the information needed for public companies, which fall under stricter regulation than private ones.
Other strictures regarding auditing evidence are laid out in guidelines issued by accounting organizations. The American Institute of Certified Public Accountants, for instance, provides information as to how audits should be conducted.
