The International Standard on Auditing (ISA) 540 (Revised) Implementation Working Group has prepared illustrative examples for auditing expected credit loss (ECL) accounting estimates. The examples illustrate how an auditor could address certain requirements of ISA 540 (Revised), and have been developed to assist the auditor in understanding how ISA 540 (Revised) may be applied to:

  • IFRS 9 Impairment (ECL) – Credit Card
  • IFRS 9 Impairment (ECL) – Significant Increase in Credit Risk
  • IFRS 9 Impairment (ECL) – Macroeconomic Inputs and Data

The examples illustrate accounting estimates with varying characteristics and degrees of complexity. Each example illustrates a selection of requirements from ISA 540 (Revised). Not all requirements are addressed in each example, nor do they cover all parts of those requirements that have been selected. The requirements selected across each example vary to illustrate different aspects of ISA 540 (Revised) and to focus on those requirements that are most relevant to the example.

The three ECL examples are intended to be read together, as requirements that are addressed in one example may also be relevant to another example. For example, the Macroeconomic Inputs and Data example is focused primarily on the audit implications of such data, and does not repeat material in the other examples, which nevertheless may be relevant and applicable to that example more broadly.

These examples do not constitute an authoritative pronouncement of the International Auditing and Assurance Standards Board, nor do they amend, extend or override the ISAs or other of the IAASB’s International Standards. It is not meant to be exhaustive and reading these examples is not a substitute for reading the ISAs.

Simple and complex illustrative examples, which demonstrate how an auditor may address selected requirements of ISA 540 (Revised) in the context of the audit of the financial statements of an entity with simple and complex accounting estimates, respectively, are also available.
