Considerations in Determining the Information to Be Used as Audit Evidence

22

ASA 500[15] requires that if information to be used as audit evidence has been prepared using the work of a management’s expert, the auditor, to the extent necessary and having regard to the significance of that expert’s work for the auditor’s purposes:

  1. Evaluates the competence, capabilities and objectivity of that expert (Ref: Para. 24-35);
  2. Obtains an understanding of the work of that expert (Ref: Para. 36-39); and
  3. Evaluates the appropriateness of that expert’s work as audit evidence for the relevant assertion (Ref: Para. 40-59).

23

In relation to the work of a management’s expert, the auditor obtains more persuasive audit evidence the higher the auditor’s assessment of risk[16]. The auditor may also consider obtaining more persuasive evidence as:

  1. The significance of that expert’s work on the financial statements increases;
  2. The ability of the company to affect the management’s expert’s judgements increases;
  3. The level of competency and capability possessed by the management expert decreases.

Competence, Capabilities and Objectivity of a Management’s Expert

24

The auditor makes reference to the requirements, application and other explanatory material contained in ASA 500 and evaluates whether the management’s expert has the necessary competence, capabilities and objectivity for the auditor’s purposes. This is ordinarily performed as part of the audit planning and risk assessment process, the timing of which may be restricted by management’s process for planning and selecting management’s experts.

25

Competence, capability and objectivity of a management’s expert impacts the degree of reliability of that expert’s work as audit evidence, that is, the extent to which the management’s expert’s work could provide persuasive audit evidence.

26

The nature and extent of procedures to evaluate the management’s expert’s competence, capability and objectivity depends on the significance of that expert’s work to the auditor’s conclusion regarding the relevant assertion and the risk of material misstatement of the relevant assertion. As the significance of the management’s expert’s work and risk of material misstatement increases, the persuasiveness of the evidence the auditor obtains for this evaluation also increases[17].

Competence

27

Competence relates to the nature and level of expertise of the management’s expert. The auditor uses professional judgement when determining the competency of a management’s expert. When evaluating competence, the auditor may consider the guidance included in ASA 500[18] as well as:

  1. The management’s expert’s experience in the type of work performed, including applicable areas of speciality within the expert’s field;
  2. The reputation and standing of the management’s expert, including:
    1. Previous experience of the auditor with the work of that expert;
    2. Enquiring of other practitioners who have used that expert or others working in the same industry;
  3. The professional certification, license or professional accreditation of the management’s expert. Experts in a specific field commonly have professional obligations under their professional or industry bodies. These obligations vary significantly and are determined by the professional or industry body[19]. The auditor’s confidence when evaluating the competency of the management’s expert may increase with that expert’s membership of professional or industry bodies that:
    1. Require professional qualification or accreditation;
    2. Subject their members to regulatory requirements/guidance;
    3. Subject their members to a specific set of standards or guidance on the expert’s services;
    4. Require continuous professional development; and
    5. Require professional obligations to be followed by their members.

28

The auditor’s evaluation of the management expert’s competence may be influenced by the management’s expert’s work environment, for example that expert’s internal quality control policies and procedures.

Capability

29

Capability relates to the ability of the management’s expert to exercise their competency in the circumstances. When evaluating capability, the auditor may consider the guidance included in ASA 500[20] as well as:

  1. Geographic location;
  2. Availability of time;
  3. Availability of resources;
  4. Instructions on scope provided by management.

Objectivity

30

Objectivity relates to the possible effects that bias, conflict of interest, or the influence of others may have on the professional or business judgement of the management’s expert. When evaluating objectivity, the auditor may consider the guidance included in ASA 500[21] as well as:

  1. Circumstances that threaten the objectivity of the management’s expert; and
  2. Whether appropriate safeguards are in place to eliminate those threats or reduce them to an acceptable level.

31

ASA 500 indicates that evidence from external sources is generally more reliable than that generated internally. The auditor may evaluate the relationship to the company of the management’s expert, specifically, whether circumstances exist that give the company the ability to significantly affect the management’s expert’s judgements about the work performed, conclusions or findings. The existence of a relationship between the management’s expert and the entity being audited may impair that expert’s ability to be objective. The risk that the objectivity of a management’s expert will be impaired increases when the management’s expert is employed by the entity or is related in some way to the entity. Where a management’s expert is employed by the entity, the auditor needs to consider whether there are any mitigating factors such as professional and/or statutory obligations governing the work of that expert that would impact on the objectivity of the management’s expert.

32

Circumstances which may threaten the objectivity of the management’s expert may include: advocacy threats, familiarity threats, self-review threats and self-interest threats[22]. Examples include economic dependency of the management’s expert on the entity and contingency based fee arrangements.

33

The evaluation of the significance of threats to objectivity and of whether there is a need for safeguards may depend upon the role of the management’s expert and the significance of that expert’s work in the context of the audit. There may be safeguards specific to the audit engagement, however there may be circumstances where safeguards cannot reduce threats to an acceptable level[23].

34

When the management’s expert is an employee of the entity, mitigating factors which enhance the ability of the management’s expert to be objective, and therefore are safeguards for the lack of independence may include:

  1. Adherence to the professional standards issued by the expert’s regulating body.
  2. Formal appointment of the management’s expert by those charged with governance and direct access to those charged with governance by that expert.

 

The basis on which the management’s expert is remunerated and/or incentives offered as part of that remuneration may be considered by the auditor when evaluating the management’s expert’s objectivity.

 

Consideration of the above may also be relevant in evaluating the objectivity of a management’s expert that is external to the entity.

Overall Evaluation of Competence, capability and objectivity of a management’s expert

35

When the management’s expert has been evaluated by the auditor as not being competent, capable and/or objective, the auditor may consider not using that expert’s work as audit evidence. In such circumstances the auditor may consider:

  1. Suggesting to management to engage a different management’s expert;
  2. Seek audit evidence from another expert including an auditor’s expert; or
  3. Changing the nature and extent of other audit procedures.

 

When the management’s expert has been evaluated by the auditor as being competent, capable and/or objective, this is not a substitute for evaluating the appropriateness of that expert’s work as audit evidence as required by ASA 500[24].

Obtaining an Understanding of the Work of a Management’s Expert

36

The auditor makes reference to the requirements, application and other explanatory material in ASA 500 when obtaining an understanding of the management’s expert’s work to evaluate whether it is appropriate for the purposes of the audit.

37

When obtaining an understanding of the management’s expert’s work, the auditor, having regard to whether the management’s expert is internal or external to the entity, may consider:

  1. The terms of the engagement between the entity and the management expert, including understanding the nature, timing and extent of work to be performed by the management’s expert and the form of any report to be provided by that expert;
  2. Whether the auditor has any prior knowledge of the management’s expert’s field of expertise, or with that expert;
  3. The economic and competitive conditions impacting the entity and its operating results;
  4. Whether there is evidence of undue management pressure on the management’s expert;
  5. The existence of controls within the entity over the work of the management’s expert (for example whether there are procedures in place to challenge or review that expert’s work, such as review by those charged with governance) or controls over the source data used in that expert’s assessment;
  6. Whether management has authorised their expert to discuss their findings or conclusions with the auditor[25];
  7. Whether the management’s expert has consented to the auditor’s intended use of their findings; and
  8. Whether the management’s expert has agreed for the auditor to access their work papers (review of the expert’s work papers is not normally required other than as considered necessary by the auditor using their professional judgement).

38

Where management has not consented for their expert to discuss their findings or conclusions with the auditor, or the management’s expert has not consented to the auditor’s intended use of their findings, the auditor may consider the guidance as provided in paragraphs 58 to 59 of this Guidance Statement.

Engagement with the Management’s Expert

39

As early as practicable during the engagement, the auditor communicates with the management’s expert, either directly or indirectly through management, and may consider the management’s expert’s approach and methodology. The auditor evaluates whether the approach and methodology is an appropriate basis for determination of the matter included in the financial report or other historical financial information. For example where management uses a valuation expert for a purchase price adjustment calculation, the auditor communicates with the management’s expert early on in the valuation process so as to understand and agree on the basis for identification of assets and the basis of the valuation methodology.

Evaluating the Appropriateness of the work of a Management’s Expert

40

ASA 500[26] contains application and other explanatory material that when evaluating the appropriateness of the management expert’s work as audit evidence for the relevant assertion, the auditor considers:

  1. The relevance and reasonableness of the management’s expert’s findings or conclusions, their consistency with other audit evidence, and whether they have been appropriately reflected in the financial report;
  2. If the management’s expert’s work involves the use of significant assumptions and methods, the relevance and reasonableness of those assumptions and methods;
  3. If the management’s expert’s work involves significant use of source data, the relevance, completeness and accuracy of that source data; and
  4. If the management’s expert’s work involves the use of information from an external information source, the relevance and reliability of that information.

41

ASA 540[27] contains requirements and application material when evaluating the appropriateness of the work of a management’s expert as audit evidence in relation to the audit of accounting estimates.

42

In addition, when evaluating the appropriateness of the work of a management’s expert, the auditor may consider the accuracy of prior period estimates made by the management’s expert. Where the auditor determines that past estimates have not been sufficiently accurate, the auditor may consider obtaining an understanding of the reasons for the inaccuracy and performing additional audit procedures as appropriate to the circumstances.

Determining the necessary audit effort for evaluating the appropriateness of management’s expert’s work

43

ASA 500 and ASA 540 do not ordinarily require that the auditor reperforms all of the work undertaken by a management’s expert. Instead, if information is to be used as audit evidence and that evidence has been prepared using the work of a management’s expert, the auditor’s responsibility is to evaluate whether the management’s expert’s work provides sufficient appropriate audit evidence to support a conclusion regarding whether the corresponding accounts or disclosures in the financial report are in conformity with the relevant financial reporting framework.

44

Consistent with paragraph 23 of this Guidance Statement, factors that may impact the persuasiveness of evidence needed when evaluating the appropriateness of the work of a management’s expert include the risk of material misstatement and the significance of the management’s expert’s work to the auditor’s conclusion, include:

  1. Consistent with ASA 330[28], the higher the risk of material misstatement for an assertion, the more persuasive the evidence needed to support a conclusion about that assertion.
  2. The significance of a management’s expert’s work refers to the degree to which the auditor gathers evidence in evaluating the management’s expert’s work to support the auditor’s conclusions about the assertion. Generally, the greater the significance of the management’s expert’s work to the auditor’s conclusion, the more persuasive the evidence from the management’s expert’s work needs to be. The significance of the management’s expert’s work stems from:
    1. The extent to which the management’s expert’s work affects the account balances, classes of transactions and disclosures in the financial report. In certain situations that work may be a primary source of audit evidence, while in other situations, the management’s expert’s work may only be used as a cross-check.
    2. The auditor’s approach to testing the relevant assertion and the availability of alternative sources of audit evidence. For example, when a company’s accounting estimate is determined principally based on the work of a management’s expert, and the auditor plans to test how management made the accounting estimate, the auditor would plan to evaluate the work of the management’s expert for evidence regarding the estimate. If the auditor tests an assertion by developing an independent expectation, the auditor would give less consideration to the work of the management’s expert.

Methods, Assumptions and Source Data

45

A management’s expert’s work involves the use of methods, assumptions and source data, the auditor ordinarily does not reperform all of the work undertaken by that expert. The auditor’s responsibility is to evaluate that the management’s expert’s work is appropriate to provide sufficient appropriate audit evidence[29] to support a conclusion regarding whether in all material respects the corresponding account balances, classes of transactions or disclosures in the financial report are in conformity with the applicable financial reporting framework. Paragraph 58 of this Guidance Statement provides additional guidance for the auditor where the auditor determines that the work of the management’s expert is not appropriate for the auditor’s purposes.

Methods

46

When a management’s expert’s work involves the use of methods, factors relevant to the auditor’s evaluation of the appropriateness of methods may include whether they are:

  1. Generally accepted within the management’s expert’s field;
  2. Justified as the appropriate valuation methodology;
  3. Consistent with the requirements of the applicable financial reporting framework; and
  4. Dependent on the use of specialised models.

47

Ordinarily the auditor is not expected to obtain access to proprietary models used by a management’s expert. Rather, the auditor’s responsibility is to obtain information to evaluate whether the model used is appropriate, robust and capable of producing outcomes that allow conformity with the applicable financial reporting framework. Depending on the model and the factors listed in paragraph 46, this may involve for example one or more of the following:

  1. Obtaining an understanding of the model;
  2. Reviewing descriptions of the model in the management’s expert’s report;
  3. Testing controls over the company’s evaluation of the management’s expert’s work;
  4. Evaluating inputs to and outputs from the model or in place of other procedures, the auditor may consider using an alternative model for comparison.

48

If the work of a management’s expert involves the use of methods relating to an accounting estimate, or developing or providing findings or conclusions relating to a point estimate or range or related disclosures for inclusion in a financial report, the auditor follows the requirements contained within ASA 540.[30]

Assumptions

49

When a management’s expert’s work involves the use of significant assumptions[31], factors relevant to the auditor’s evaluation of the reasonableness of those assumptions may include consideration of:

  1. The degree of estimation uncertainty associated with the management’s expert’s underlying assumptions and the degree of stress testing undertaken;
  2. Significant changes during the course of the audit that may affect the appropriateness of the assumptions used; and
  3. Consistency of those assumptions with relevant information. The following examples may be considered relevant:
    • assumptions generally accepted within the management’s expert’s field and are they appropriate for financial reporting purposes;
    • industry, regulatory and other external factors, including economic conditions;
    • existing market information;
    • historical or recent experience, along with changes in conditions and events affecting the company;
    • significant assumptions used in other estimates tested in the company’s financial report.

50

Assumptions relating to accounting estimates that are made or identified by a management’s expert become management’s assumptions when used by management in making an accounting estimate[32]. In these circumstances, the auditor applies the relevant requirements of ASA 540 to those assumptions.

Source Data Used by the Management’s Expert

51

The auditor may consider whether the source data is sufficiently relevant and reliable for their purposes, including procedures relating to establishing the accuracy and completeness of the data and evaluating whether the data is sufficiently precise and detailed. The extent of the auditor’s procedures is dependent on the nature and risk of the source data and the materiality of the underlying balance, transaction and/or disclosure to which it relates. When a management’s expert’s work involves the use of source data that is significant to that expert’s work, the auditor may evaluate that expert’s work on source data. Procedures for the auditor may include considering how the management’s expert determined that the source data was relevant and reliable, including as necessary in the circumstances how the management’s expert determined that the source data was complete and accurate.

52

In many cases, the auditor may test the source data directly, particularly where the data is internally produced by the company. However, in other cases, for example when the nature of the source data used by the management’s expert is highly technical, that expert may test the source data. If the management’s expert has tested the source data, the auditor considers the most appropriate way of evaluating whether the source data is sufficiently reliable for their purposes such as enquiry of that expert as to the scope and nature of the testing they performed, supervision or review of that expert’s tests and the involvement of an auditor’s expert.

53

If the work of a management’s expert involves sources of data relating to an accounting estimate, or developing or providing findings or conclusions relating to a point estimate or related disclosures for inclusion in a financial report, the auditor may find the requirements and application material of ASA 540[33] helpful.

The Findings and Conclusions of the Management’s Expert

54

The auditor may consider the final findings and conclusions in the agreed form of report of the management’s expert. The auditor, using their professional judgement, considers what additional procedures are required, particularly when the risk of material misstatement has been assessed as significant. The auditor may consider performing more extensive procedures or engaging an auditor’s expert to review some or all of the work of the management’s expert. Specific procedures to evaluate the reasonableness of the management’s expert’s work for the auditor’s purposes may include:

  1. Enquiries of the management’s expert.
  2. Comparing the management’s expert’s final report to the draft report (if a draft report is provided) and understanding and enquiring into material differences and consideration of additional audit procedures as appropriate.
  3. Corroborative procedures, such as:
    • observing the management’s expert’s work;
    • examining published data, such as statistical reports from reputable, authoritative sources;
    • confirming relevant matters with relevant third parties;
    • performing detailed analytical procedures; and/or
    • re-performing calculations including sensitivity analysis on key inputs.
  4. Consultation with an auditor’s expert with relevant expertise when, for example, the findings or conclusions of the management’s expert are not consistent with other audit evidence or the findings indicate an error, deviation, deficiency in internal control, or other significant matter or the scope of the engagement or adequacy of evidence is insufficient.
  5. Discussion of the management’s expert’s report with management and if appropriate those charged with governance, including understanding their evaluation of the expert’s findings.

55

Relevant factors when evaluating the relevance and reasonableness of the findings or conclusions of the management’s expert from that expert’s report, may include whether they are:

  1. Consistent with the auditor’s understanding of the entity and its environment;
  2. Clearly expressed, including reference to the objectives agreed with management, the scope of the work performed and standards applied;
  3. Consistent with the results of other audit procedures;
  4. Cross-checked against one or more other methodologies;
  5. Based on an appropriate period/point in time and take into account events occurring after that date, where relevant;
  6. Subject to any reservation, limitation or restriction on use, and if so, whether this has implications for the auditor; and
  7. Based on appropriate consideration of errors, deviations, deficiencies in internal controls or other significant matters identified by the management’s expert.

Evaluation of the Work Undertaken by the Management’s Expert

56

The auditor evaluates the appropriateness of the management’s expert’s work as audit evidence for the relevant assertion[34].

57

Considerations when evaluating the appropriateness of the management’s expert’s work may include considering the relevance and reliability of that work including:

  1. The results of the auditor’s procedures over the competence, capability and objectivity of the management’s expert;
  2. The results of the auditor’s procedures over the management’s expert’s methods, assumptions and source data;
  3. The nature of any restrictions, disclaimers or limitations in the management’s expert’s report;
  4. The consistency of the management’s expert’s work with other evidence obtained by the auditor and the auditor’s understanding of the company and its environment.

58

If the auditor determines that the work of the management’s expert is not appropriate for the auditor’s purposes, or does not address material errors, deviations, deficiencies in internal controls or other material matters, the auditor may agree with management on the nature and extent of further work to be performed by the management’s expert; or performs additional audit procedures appropriate to the circumstances[35]. The auditor may communicate this with those charged with governance. If the matter cannot be resolved, this is reported to those charged with governance and it may be necessary for the auditor to express a modified opinion in the auditor’s report if the auditor cannot obtain sufficient appropriate audit evidence.

59

When the auditor concludes that the work of the management’s expert is appropriate for the auditor’s purposes, the auditor may use that expert’s findings or conclusions as appropriate audit evidence. The auditor then determines whether the management’s expert’s findings or conclusions have been accurately reflected in the financial report or other historical financial information including relevant disclosures.
