Audit Definition

Audit Definition the word audit is derived from the Latin word “AUDIRE” which means to hear. Initially, the auditor was a person appointed by the owners to check account whenever the suspected fraud, he was to hear explanation given by the person responsible for financial transactions. The scope of the audit was quite limited as during those days most businesses were small and owner-operated. Since these owners-managers had extensive first-hand knowledge of the business and its operations, they had little need for the independent auditor. The owners were chiefly interested in ascertaining whether all cash receipts and payments had been properly accounted for and checking the records for possible employee fraud.

Put differently, initially, the aim of the audit was to know whether any cash had been embezzled and if so, who embezzled it and what amount was involved. But as the businesses grew both in size and complexity, the owners found it more difficult to maintain complete knowledge of all aspect of their business. Especially emergence of joint stock companies changed the approach of auditing as ownership was pestered from management. The emphasis now is clearly on the verification of accounting data with a view on the reliability of the accounting statement.

Some of the Audit Definition according to different authors are as follows

Audit Definition according to Spicer and Pegler
An audit may be said to be such an examination of the books, accounts and vouchers of a business as well enable the auditor to satisfy that the Balance Sheet is properly drawn up, so as to give a true and fair view of the state of affairs of the business and whether the Profit or Loss for the financial period according to the best of his information and the explanations given to him and as shown by the books, and if not, in what respect he is not satisfied."
Audit Definition according to Lawrence R. Dicksee
an audit is an examination of accounting records undertaken with a view to establishing whether they correctly and completely reflect the transactions to which they relate. In some instances, it may be necessary to ascertain whether the transactions themselves are supported by authority
Audit Definition according to R. K. Mautz

Audit Definition according to International Federation of Accountants (IFAC)

Audit Procedure

Audit Definition Standards + Procedures

Review techniques are used by inspectors to decide the nature of the monetary data being given by their customers. The correct strategies utilized will fluctuate by customer, contingent upon the idea of the business and the review attestations that the inspectors need to demonstrate. Here are a few general characterizations of Audit procedures

  • Classification testing. Audit procedures are used to determine whether activities were classified accurately in the accounting records. For example, purchase records for fixed assets can be reviewed to see if they were correctly classified within the right fixed asset account
  • Completeness testing. Audit procedures can test to see if any transactions are missing from the accounting records. For example, the client's bank statements could be perused to see if any payments to suppliers were not recorded in the books, or if cash receipts from customers were not recorded. As another example, inquiries can be made with management and third parties to see if the client has additional obligations that have not been recognized in the financial statements
  • Cutoff testing. Audit procedures are used to determine whether transactions have been recorded within the correct reporting period. For example, the shipping log can be reviewed to see if shipments to customers on the last day of the month were recorded within the correct period
  • Event testing. Review strategies can be built to decide if the exchanges that a customer is asserting have really happened. For instance, one strategy may require the customer to indicate particular solicitations that are recorded on the business record, alongside supporting documentation, for example, a client request and sending documentation.
  • Existence testing. Audit procedures are used to determine whether assets exist. For example, the auditors can observe an inventory being taken, to see if the inventory stated in the accounting records actually exists
  • Rights and commitments testing. Review methodology can be pursued to check whether a customer really claims the majority of its advantages. For instance, the request can be made to check whether the stock is really possessed by the customer, or in the event that it is rather being hung on committal from an outsider.
  • Valuation testing. Audit procedures are used to determine whether the valuations at which assets and liabilities are recorded in a client's books are correct. For example, one procedure would be to check market pricing data to see if the ending values of marketable securities are correct.

A complete set of Audit procedures is needed before the auditor has enough information to decide whether a client's financial statements fairly represent its financial results, financial position, and cash flows. For more detail Click Here
