Auditing Standard ASA 230 Audit Documentation (as amended to 10 March 2021) is set out in paragraphs Aus 0.1 to A24 and Appendix 1.

This Auditing Standard is to be read in conjunction with ASA 101 Preamble to AUASB Standards, which sets out how AUASB Standards are to be understood, interpreted and applied.  This Auditing Standard is to be read also in conjunction with ASA 200 Overall Objectives of the Independent Auditor and the Conduct of an Audit in Accordance with Australian Auditing Standards.

 

This Auditing Standard conforms with International Standard on Auditing ISA 230 Audit Documentation issued by the International Auditing and Assurance Standards Board (IAASB), an independent standardsetting board of the International Federation of Accountants (IFAC).

Paragraphs that have been added to this Auditing Standard (and do not appear in the text of the equivalent ISA) are identified with the prefix “Aus”.

The following requirement is additional to ISA 230:

Paragraph Aus 12.1 - Where, in rare and exceptional circumstances, factors outside the auditor’s control prevent the auditor from complying with an essential procedure contained within a relevant requirement, the auditor shall document:

(a)           The circumstances surrounding the inability to comply;

(b)           The reasons for the inability to comply; and

(c)           Justification of how alternative audit procedures achieve the objectives of the requirement. 
(Ref: Para. Aus 12.1)

This Auditing Standard incorporates terminology and definitions used in Australia.

The equivalent requirements and related application and other explanatory material included in ISA 230 in respect of “relevant ethical requirements”, have been included in Auditing Standard, ASA 102 Compliance with Ethical Requirements when Performing Audits, Reviews and Other Assurance Engagements.  There is no international equivalent to ASA 102.

Compliance with this Auditing Standard enables compliance with ISA 230.

 

Auditing Standard ASA 230

The Auditing and Assurance Standards Board (AUASB) made Auditing Standard ASA 230 Audit Documentation pursuant to section 227B of the Australian Securities and Investments Commission Act 2001 and section 336 of the Corporations Act 2001, on 27 October 2009.

This compiled version of ASA 230 incorporates subsequent amendments contained in other Auditing Standards made by the AUASB up to and including 10 March 2021 (see Compilation Details).

Aus 0.1 This Auditing Standard applies to:

(a) an audit of a financial report for a financial year, or an audit of a financial report for a halfyear, in accordance with the Corporations Act 2001; and

(b) an audit of a financial report, or a complete set of financial statements, for any other purpose.

Aus 0.2 This Auditing Standard also applies, as appropriate, to an audit of other historical financial information.

Aus 0.3 This Auditing Standard is operative for financial reporting periods commencing on or after 1 January 2010.  [Note: For operative dates of paragraphs changed or added by an Amending Standard, see Compilation Details.]

  1. This Auditing Standard deals with the auditor’s responsibility to prepare audit documentation for an audit of a financial report.  Appendix 1 lists other Auditing Standards that contain specific documentation requirements and guidance.  The specific documentation requirements of other Auditing Standards do not limit the application of this Auditing Standard.  Law or regulation may establish additional documentation requirements.

2.                   Audit documentation that meets the requirements of this Auditing Standard and the specific documentation requirements of other relevant Australian Auditing Standards provides:

(a)                Evidence of the auditor’s basis for a conclusion about the achievement of the overall objective of the auditor;[1] and

(b)                Evidence that the audit was planned and performed in accordance with Australian Auditing Standards and applicable legal and regulatory requirements. 

3.                   Audit documentation serves a number of additional purposes, including the following:

4.                   [Deleted by the AUASB.  Refer Aus 0.3]

5.                   The objective of the auditor is to prepare documentation that provides:

(a)                A sufficient and appropriate record of the basis for the auditor’s report; and

(b)                Evidence that the audit was planned and performed in accordance with Australian Auditing Standards and applicable legal and regulatory requirements. 

6.                   For the purposes of this Auditing Standard, the following terms have the meanings attributed below:

(a)                Audit documentation means the record of audit procedures performed, relevant audit evidence obtained, and conclusions the auditor reached (terms such as “working papers” or “workpapers” are also sometimes used).

(b)                Audit file means one or more folders or other storage media, in physical or electronic form, containing the records that comprise the audit documentation for a specific engagement. 

(c)                Experienced auditor means an individual (whether internal or external to the firm) who has practical audit experience, and a reasonable understanding of:

(i)                 Audit processes;

(ii)               Australian Auditing Standards and applicable legal and regulatory requirements;

(iii)             The business environment in which the entity operates; and

(iv)             Auditing and financial reporting issues relevant to the entity’s industry.

7.                   The auditor shall prepare audit documentation on a timely basis.  (Ref: Para. A1)

8.                   The auditor shall prepare audit documentation that is sufficient to enable an experienced auditor, having no previous connection with the audit, to understand:  (Ref: Para. A2A5, A16A17)

(a)                The nature, timing, and extent of the audit procedures performed to comply with the Australian Auditing Standards and applicable legal and regulatory requirements; (Ref: Para. A6A7)

(b)                The results of the audit procedures performed, and the audit evidence obtained; and

(c)                Significant matters arising during the audit, the conclusions reached thereon, and significant professional judgements made in reaching those conclusions.  (Ref: Para. A8A11)

9.                   In documenting the nature, timing and extent of audit procedures performed, the auditor shall record:

(a)                The identifying characteristics of the specific items or matters tested; (Ref: Para. A12)

11.               If the auditor identified information that is inconsistent with the auditor’s final conclusion regarding a significant matter, the auditor shall document how the auditor addressed the inconsistency.  (Ref: Para. A15)

12.               [Deleted by the AUASB.  Refer Aus 12.1]

Aus 12.1 Where, in rare and exceptional circumstances, factors outside the auditor’s control prevent the auditor from complying with an essential procedure contained within a relevant requirement, the auditor shall document:  (Ref: Para. A18A19)

(a) The circumstances surrounding the inability to comply;

(b) The reasons for the inability to comply; and

(c) Justification of how alternative audit procedures achieve the objectives of the requirement.

(a)                The circumstances encountered;

(b)                The new or additional audit procedures performed, audit evidence obtained, and conclusions reached, and their effect on the auditor’s report; and

(c)                When and by whom the resulting changes to audit documentation were made and reviewed.

15.               After the assembly of the final audit file has been completed, the auditor shall not delete or discard audit documentation of any nature before the end of its retention period. 
(Ref: Para. A23-Aus A23.2)

16.               In circumstances other than those envisaged in paragraph 13 of this Auditing Standard where the auditor finds it necessary to modify existing audit documentation or add new audit documentation after the assembly of the final audit file has been completed, the auditor shall, regardless of the nature of the modifications or additions, document:  (Ref: Para. A24)

(a)                The specific reasons for making them; and

(b)                When and by whom they were made and reviewed. 

* * *

A1.             Preparing sufficient and appropriate audit documentation on a timely basis helps to enhance the quality of the audit and facilitates the effective review and evaluation of the audit evidence obtained and conclusions reached before the auditor’s report is finalised.  Documentation prepared after the audit work has been performed is likely to be less accurate than documentation prepared at the time such work is performed. 

A2.             The form, content and extent of audit documentation depend on factors such as:

A3.             Audit documentation may be recorded on paper or on electronic or other media.  Examples of audit documentation include:

The auditor may include abstracts or copies of the entity’s records (for example, significant and specific contracts and agreements) as part of audit documentation.  Audit documentation, however, is not a substitute for the entity’s accounting records.

A4.             The auditor need not include in audit documentation superseded drafts of working papers and financial reports, notes that reflect incomplete or preliminary thinking, previous copies of documents corrected for typographical or other errors, and duplicates of documents.

A5.             Oral explanations by the auditor, on their own, do not represent adequate support for the work the auditor performed or conclusions the auditor reached, but may be used to explain or clarify information contained in the audit documentation.

A6.             In principle, compliance with the requirements of this Auditing Standard will result in the audit documentation being sufficient and appropriate in the circumstances.  Other Australian Auditing Standards contain specific documentation requirements that are intended to clarify the application of this Auditing Standard in the particular circumstances of those other Australian Auditing Standards.  The specific documentation requirements of other Australian Auditing Standards do not limit the application of this Auditing Standard.  Furthermore, the absence of a documentation requirement in any particular Auditing Standard is not intended to suggest that there is no documentation that will be prepared as a result of complying with that Auditing Standard. 

A7.             Audit documentation provides evidence that the audit complies with the Australian Auditing Standards.  However, it is neither necessary nor practicable for the auditor to document every matter considered, or professional judgement made, in an audit.  Further, it is unnecessary for the auditor to document separately (as in a checklist, for example) compliance with matters for which compliance is demonstrated by documents included within the audit file.  For example:

A8.             Judging the significance of a matter requires an objective analysis of the facts and circumstances.  Examples of significant matters include:

A9.             An important factor in determining the form, content and extent of audit documentation of significant matters is the extent of professional judgement exercised in performing the work and evaluating the results.  Documentation of the professional judgements made, where significant, serves to explain the auditor’s conclusions and to reinforce the quality of the judgement.  Such matters are of particular interest to those responsible for reviewing audit documentation, including those carrying out subsequent audits when reviewing matters of continuing significance (for example, when performing a retrospective review of accounting estimates). 

A10.         Some examples of circumstances in which, in accordance with paragraph 8, it is appropriate to prepare audit documentation relating to the use of professional judgement include, where the matters and judgements are significant: 

A11.         The auditor may consider it helpful to prepare and retain as part of the audit documentation a summary (sometimes known as a completion memorandum) that describes the significant matters identified during the audit and how they were addressed, or that includes crossreferences to other relevant supporting audit documentation that provides such information.  Such a summary may facilitate effective and efficient reviews and inspections of the audit documentation, particularly for large and complex audits.  Further, the preparation of such a summary may assist the auditor’s consideration of the significant matters.  It may also help the auditor to consider whether, in light of the audit procedures performed and conclusions reached, there is any individual relevant Auditing Standard objective that the auditor cannot achieve that would prevent the auditor from achieving the overall objectives of the auditor.

A12.         Recording the identifying characteristics serves a number of purposes.  For example, it enables the engagement team to be accountable for its work and facilitates the investigation of exceptions or inconsistencies.  Identifying characteristics will vary with the nature of the audit procedure and the item or matter tested.  For example:

A13.         ASA 220 contains requirements and guidance on the  review of audit documentation.[8]  The requirement to document who reviewed the audit work performed does not imply a need for each specific working paper to include evidence of review.  The requirement, however, means documenting what audit work was reviewed, who reviewed such work, and when it was reviewed. 

A14.         The documentation is not limited to records prepared by the auditor but may include other appropriate records such as minutes of meetings prepared by the entity’s personnel and agreed by the auditor.  Others with whom the auditor may discuss significant matters may include other personnel within the entity, and external parties, such as persons providing professional advice to the entity.

A15.         The requirement to document how the auditor addressed inconsistencies in information does not imply that the auditor needs to retain documentation that is incorrect or superseded. 

A16.         The audit documentation for the audit of a smaller entity is generally less extensive than that for the audit of a larger entity.  Further, in the case of an audit where the engagement partner performs all the audit work, the documentation will not include matters that might have to be documented solely to inform or instruct members of an engagement team, or to provide evidence of review by other members of the team (for example, there will be no matters to document relating to team discussions or supervision).  Nevertheless, the engagement partner complies with the overriding requirement in paragraph 8 to prepare audit documentation that can be understood by an experienced auditor, as the audit documentation may be subject to review by external parties for regulatory or other purposes.

A17.         When preparing audit documentation, the auditor of a smaller entity may also find it helpful and efficient to record various aspects of the audit together in a single document, with crossreferences to supporting working papers as appropriate.  Examples of matters that may be documented together in the audit of a smaller entity include the understanding of the entity and its environment, the applicable financial reporting framework, and the entity’s system of internal control, the overall audit strategy and audit plan, materiality determined in accordance with ASA 320,[9] assessed risks, significant matters noted during the audit, and conclusions reached. 

A18.         The requirements of the Australian Auditing Standards are designed to enable the auditor to achieve the objectives specified in the Australian Auditing Standards, and thereby the overall objectives of the auditor.  Accordingly, other than in rare and exceptional circumstances, the Australian Auditing Standards call for compliance with each requirement that is relevant in the circumstances of the audit. 

Aus A18.1 ASA 200 contains a requirement regarding the situation, where, in rare and exceptional circumstances, factors outside the auditor’s control prevent the auditor from complying with an essential procedure contained within a relevant requirement.

A19.         The documentation requirement applies only to requirements that are relevant in the circumstances.  A requirement is not relevant[10] only in the cases where:

(a)                The entire Auditing Standard is not relevant (for example, if an entity does not have an internal audit function, nothing in ASA 610[11] is relevant); or

(b)                The requirement is conditional and the condition does not exist (for example, the requirement to modify the auditor’s opinion where there is an inability to obtain sufficient appropriate audit evidence, and there is no such inability). 

A20.         Examples of exceptional circumstances include facts which become known to the auditor after the date of the auditor’s report but which existed at that date and which, if known at that date, might have caused the financial report to be amended or the auditor to modify the opinion in the auditor’s report.[12]  The resulting changes to the audit documentation are reviewed in accordance with the review responsibilities set out in ASA 220[13]. 

A21.         ASQM 1 requires firms’ systems of quality management to establish a quality objective that addresses the assembly of engagement documentation on a timely basis after the date of the engagement reports.[14]  An appropriate time limit within which to complete the assembly of the final audit file is ordinarily not more than 60 days after the date of the auditor’s report.[15]

A22.         The completion of the assembly of the final audit file after the date of the auditor’s report is an administrative process that does not involve the performance of new audit procedures or the drawing of new conclusions.  Changes may, however, be made to the audit documentation during the final assembly process if they are administrative in nature.  Examples of such changes include:

A23.         ASQM 1 requires firms’ systems of quality management to establish a quality objective to address the appropriate maintenance and retention of engagement documentation to meet the needs of the firm and to comply with law, regulation, relevant ethical requirements, or AUASB Standards.[16]  The retention period for audit engagements ordinarily is no shorter than five years from the date of the auditor’s report, or, if later, the date of the auditor’s report on the group financial reports, when applicable.[17]

Aus A23.1 Under section 307B of the Corporations Act 2001, the auditor or member of an audit firm is required to retain all audit working papers prepared by or for, or considered or used by, the auditor in accordance with the requirements of the Australian Auditing Standards until:

(a) The end of seven years after the date of the audit report prepared in relation to the audit or review to which the audit working papers relate; or

(b) An earlier date determined by the Australian Securities and Investments Commission for the audit working papers.

Aus A23.2 Relevant legislation or regulation, other than the Corporations Act 2001, may require the retention of audit working papers for specified periods. 

A24.         An example of a circumstance in which the auditor may find it necessary to modify existing audit documentation or add new audit documentation after file assembly has been completed is the need to clarify existing audit documentation arising from comments received during monitoring activities or external inspections.
