Appointment and engagement terms

The importance of achieving audit objectives

ISA 200 highlights the importance of objectives in auditing standards. Understanding ISA 200 is fundamental to understanding the challenge of implementing ISAs. This guide seeks to help auditors understand the overall objectives of the auditor and how they relate to the individual objectives and requirements in ISAs, and the role of professional judgement and scepticism.

Auditor independence

Auditor independence refers to the independence of the external auditor. It is characterised by integrity and an objective approach to the audit process. The concept requires the auditor to carry out his or her work freely and in an objective manner.

Risk assessment, internal control and response to risks in external audit

Supporting audit quality

Improving audit quality using root cause analysis

With external audits under unprecedented levels of scrutiny, root cause analysis (RCA) can be a useful tool for those tasked with improving audit quality. The Audit and Assurance Faculty has published this practical paper for its members outlining what RCA is and what auditors need to consider to make the most of this useful tool.

The audit of related parties in practice

In the light of increasing public interest in the quality of audits, the faculty considers that the audit of related parties is an area where further improvements in audit quality and efficiency can be achieved.

Applying professional scepticism and judgement

Scepticism: the practitioners' take

Professional scepticism is central to the work of auditors and yet audit regulators and others continue to express concerns that auditors are not sufficiently sceptical. This report explores what auditors and other stakeholders think about how it can be enhanced and who is responsible for it.

Auditing accounting estimates

Documenting the audit of accounting estimates under ISA 540 (Revised)

Documenting the audit of accounting estimates is important because it provides evidence that the audit complies with ISAs. ISA 540 (Revised) Auditing accounting estimates and related disclosures introduces enhanced documentation requirements and this Audit and Assurance guide provides information and guidance on what needs to be documented, and when, in your audit of accounting estimates.

Inherent risk factors in auditing accounting estimates

ISA 540 (Revised) Auditing accounting estimates and related disclosures introduces the concept of inherent risk factors and requires the auditor to consider the degree to which accounting estimates are affected by these factors in identifying and assessing the risks of material misstatement.

Auditing accounting estimates that give rise to significant risks

When performing an audit of accounting estimates under ISA 540 (Revised) Auditing accounting estimates and related disclosures, an auditor will need to use their own judgement to determine whether any risks of material misstatement identified or assessed in relation to accounting estimates give rise to a significant risk.

Reporting and completion
