Relevance to Auditors, Independent Reviewers & Accountants:

  • As an auditor and independent reviewer, you need to comply with International Standards on Auditing and other Assurance Services, and thus you need knowledge of newly revised standards that are approved as well as when they become effective.
  • Failure to adhere to ISAs may be interpreted as negligence and you could be held liable.
  • Auditors, Independent Reviewers and Accountants should be aware of the latest versions of handbooks containing standards issued by regulators and standard-setting boards, such as the IAASB Handbook.
  • SA RAs should especially be aware when the international pronouncements are adopted by IRBA for use in SA.
