With the formation of the Auditing Practices Committee (now known as the Auditing and Assurance Standards Board) in 1982, the Council of the Institute has been issuing a series of Statements on Standard Auditing Practices (SAPs). SAPs have been renamed as Auditing and Assurance Standards (AASs). The Auditing and Assurance Standards (hitherto known as SAPs) lay down the principles governing an audit. These principles apply whenever an independent audit is carried out. Auditing and Assurance Standards become mandatory on the dates specified in the respective AAS. Their mandatory status implies that, while discharging their attest function, it will be the duty of the members of the Institute to ensure that the AASs are followed in the audit of financial information covered by their audit reports. If, for any reason, a member has not been able to perform an audit in accordance with the AASs, his report should draw attention to the material departures therefrom.
