IAASB issues ISA 540 (Revised)

  • IAASB (International Auditing and Assurance Standards Board) (lt gray) Image

03 Oct 2018

The International Auditing and Assurance Standards Board (IAASB) has released a revised version of International Standard on Auditing (ISA) 540 (Revised) for the audit of accounting estimates and related disclosures.

This revised standard is the first to be completed as part of the IAASB’s broader programme, Addressing the Fundamental Elements of an Audit, and is an important part of the IAASB’s efforts to improve audit quality globally.

The revisions include:

  • an enhanced risk assessment that requires auditors to consider complexity, subjectivity and other inherent risk factors in addition to estimation uncertainty. This will drive auditors to think more deeply about the risks inherent to accounting estimates;
  • a closer link between the enhanced risk assessment and the methods, data and assumptions used in making accounting estimates, including the use of complex models;
  • specific material to show how the standard is scalable to all types of accounting estimates;
  • emphasis on the importance of applying appropriate professional scepticism when auditing accounting estimates to foster a more independent and challenging sceptical mindset in auditors.

ISA 540 (Revised) becomes effective for financial statement audits for periods beginning on or after 15 December 2019.

For further details on the updates see the International Federation of Accountants (IFAC) website.
