Narrow-Scope Amendments to IAASB Standards Arising from the IESBA’s Using the Work of an External Expert Project

These amendments respond to the International Ethics Standards Board for Accountants’ recently approved revisions to its International Code of Ethics for Professional Accountants (including International Independence Standards), which introduced, among other provisions, explicit ethical requirements for using the work of external experts in audit, assurance, and non-assurance engagements. The IAASB’s updates reflect ongoing collaboration and coordination between the IAASB and IESBA and help to maintain interoperability between the IAASB standards and the IESBA Code.

The targeted amendments affect the following IAASB standards:

• ISA 620, Using the Work of an Auditor’s Expert
• ISRE 2400 (Revised), Engagements to Review Historical Financial Statements
• ISAE 3000 (Revised), Assurance Engagements Other than Audits or Reviews of Historical Financial Information
• ISRS 4400 (Revised), Agreed-upon Procedures Engagements
