About This Course

Course Information

Accounting estimates are at the centre of modern audits, often involving significant judgement, complexity, and uncertainty. ISA 540 (Revised) sets out the auditor’s responsibilities for evaluating accounting estimates and related disclosures to ensure they are reasonable and free from bias. This refresher course is designed for auditors and accounting professionals seeking to strengthen their grasp of the standard and its practical application. Throughout this course, you’ll revisit key concepts, explore inherent risk factors, learn how to respond to and document estimation risks, and understand the role of professional scepticism in enhancing audit quality. You’ll also study real-world examples, communication challenges, and recent developments that have influenced audit judgments in areas such as fair-value measurement, expected credit losses, and post-pandemic economic uncertainty

What You Will Learn

  • Explain why accounting estimates are a primary source of material misstatement and how ISA 540 (Revised) addresses estimation risk through a risk-based framework
  • Distinguish between the three inherent risk factors (complexity, subjectivity, and estimation uncertainty) and assess how they interact in estimates such as expected credit losses and goodwill impairment
  • Evaluate management's estimation process by testing the method, data inputs, and assumptions against observable evidence and the applicable reporting framework
  • Apply the three audit response approaches under ISA 540 (Revised): testing management's process, developing an independent point estimate, and reviewing subsequent events
  • Identify indicators of management bias across multiple estimates and assess whether patterns of directional optimism or conservatism affect the financial statements
  • Describe how professional scepticism guards against confirmation bias, anchoring bias, and automation bias when challenging management's assumptions and models
  • Recognise recurring inspection findings from regulators (PCAOB, FRC, IAASA, IFIAR) and apply lessons on documentation quality, governance communication, and the linkage between risk assessment and audit response
