Auditing refers to a systematic and independent examination of books, accounts, documents and vouchers of an organization to ascertain how far the financial statements present a true and fair view of the concern. It also attempts to ensure that the books of accounts are properly maintained by the concern as required by law. Auditing has become such a ubiquitous phenomenon in the corporate and the public sector that academics started identifying an "Audit Society". The auditor perceives and recognizes the propositions before him/her for examination, obtains evidence, evaluates the same and formulates an opinion on the basis of his judgement which is communicated through his audit report.
