Introduction & Scope (Para. 1-3)
Introduction & Scope
Scope of HKSA 540 (Revised)
Deals with auditor's responsibilities for accounting estimates and related disclosures. It expands on how to apply:
- HKSA 315 (Revised 2019) โ Risk identification
- HKSA 330 โ Responses to assessed risks
- HKSA 450 โ Evaluation of misstatements
- HKSA 500 โ Audit evidence
Effective Date: Audits of financial statements for periods beginning on or after 15 December 2019.
Key Characteristics of Accounting Estimates
Monetary amounts that cannot be directly observed and are subject to estimation uncertainty. Key elements:
- Estimation uncertainty
- Management judgment
- Complexity
- Susceptibility to misstatement
Scalability
| Scenario | Expected Audit Effort |
|---|---|
| Low estimation uncertainty, complexity, subjectivity | Less extensive procedures |
| High estimation uncertainty, complexity, subjectivity | Much more extensive procedures |

Key Concepts & Definitions (Para. 4-12)
Key Concepts & Definitions
Inherent Risk Factors (Para. 4, A8-A9)
Primary factors affecting susceptibility to misstatement:
Primary Inherent Risk Factors:
- Estimation uncertainty โ Lack of precision in measurement
- Complexity โ Difficulty in understanding/applying methods
- Subjectivity โ Degree of judgment required
Additional factors: change, susceptibility to management bias, other uncertainty.
Professional Skepticism (Para. 8, A11)
Importance increases when:
- Greater estimation uncertainty
- Greater complexity, subjectivity
- Higher susceptibility to management bias or fraud
Key Definitions (Para. 12)
| Term | Definition |
|---|---|
| Accounting estimate | Monetary amount subject to estimation uncertainty |
| Estimation uncertainty | Susceptibility to inherent lack of precision in measurement |
| Management bias | Lack of neutrality in preparation of information |
| Management's point estimate | Amount selected by management for recognition/disclosure |
| Auditor's point estimate/range | Amount/range developed by auditor to evaluate management's estimate |
| Outcome of an accounting estimate | Actual monetary amount resulting from resolution of the transaction/event |

Risk Assessment Procedures (Para. 13-15)
Risk Assessment Procedures
Understanding the Entity and Its Environment (Para. 13(a)-(d))
Obtain understanding of:
- Transactions/conditions giving rise to estimates
- Requirements of applicable financial reporting framework
- Regulatory factors (e.g., prudential supervision)
- Nature of expected estimates and disclosures
Understanding Internal Control (Para. 13(e)-(j))
Key areas to understand:
| Area | Key Considerations |
|---|---|
| Oversight & governance | Culture, skills, independence of those charged with governance |
| Specialized skills/knowledge | Use of management's expert |
| Risk assessment process | Changes in framework, data sources, IT, key personnel |
| Information system | How methods, assumptions, data are identified; how estimation uncertainty is addressed |
| Controls | Review/approval, segregation of duties, IT controls |
| Review of previous estimates | Effectiveness of management's process, bias indicators |
Review of Previous Estimates (Para. 14)
Purpose: Assist in identifying and assessing risks of material misstatement in the current period.
Note: Difference between outcome and previous amount does not necessarily represent a misstatement.
Ad Space
Identifying & Assessing Risks (Para. 16-17)
Identifying & Assessing Risks of Material Misstatement
Risk Identification Requirements (Para. 16)
Take into account:
- Degree of estimation uncertainty (A72-A75)
- Does framework require high-uncertainty methods/assumptions?
- Business environment (e.g., market turmoil)
- Can management make precise predictions?
- Degree of complexity, subjectivity, or other inherent risk factors (A76-A79)
- Selection/application of method, assumptions, data
- Selection of management's point estimate and disclosures
Important: The size of the amount recognized is not an indicator of susceptibility to misstatement.
Significant Risks (Para. 17, A80)
If a significant risk exists, auditor shall:
- Identify controls that address that risk
- Evaluate whether controls have been designed effectively
- Determine whether they have been implemented
Ad Space
Responses to Assessed Risks (Para. 18-30)
Responses to Assessed Risks of Material Misstatement
Three Testing Approaches (Para. 18)
Auditor shall include one or more of the following:
| Approach | Description | When Appropriate |
|---|---|---|
| Events approach | Obtain evidence from events occurring up to date of auditor's report | Simple estimates (e.g., bonus paid shortly after year-end) |
| Test management's process | Test how management made the estimate | Prior period review suggests process is appropriate; routine processing |
| Auditor's estimate approach | Develop auditor's point estimate or range | When management's process is not reliable |
Testing Management's Process (Para. 22-27)
Address:
- Methods (Para. 23): Appropriateness, bias indicators, mathematical accuracy, complex models
- Significant assumptions (Para. 24): Appropriateness, consistency, management's intent/ability
- Data (Para. 25): Appropriateness, relevance, reliability, interpretation
- Point estimate & disclosures (Para. 26-27): Understanding and addressing estimation uncertainty
If management has not taken appropriate steps: Request management to perform additional procedures. If insufficient, develop an auditor's point estimate or range.

Management Bias & Overall Evaluation (Para. 32-36)
Management Bias & Overall Evaluation
Indicators of Possible Management Bias (Para. 32, A133-A136)
Evaluate whether judgments/decisions, even if individually reasonable, indicate possible management bias.
Examples of bias indicators:
- Changes in estimate when method has not changed
- Assumptions at one end of a reasonable range
- Selection of assumptions resulting in more favorable outcome
- Sensitivity analysis shows material impact but no disclosure
Note: Where there is intention to mislead, management bias is fraudulent in nature.
Overall Evaluation (Para. 33-36)
Evaluate whether:
- Assessments of risks remain appropriate
- Management's decisions are in accordance with the framework
- Sufficient appropriate audit evidence has been obtained
Determine whether estimates and disclosures are reasonable or misstated.
| Framework Type | Evaluation Focus |
|---|---|
| Fair presentation | Whether additional disclosures beyond those required are necessary for fair presentation |
| Compliance | Whether disclosures are necessary for financial statements not to be misleading |

Written Representations & Communication (Para. 37-38)
Written Representations & Communication
Written Representations (Para. 37, A145)
Request written representations from management (and when appropriate, those charged with governance) about:
- Whether methods, significant assumptions, and data used are appropriate
- Whether related disclosures are appropriate to achieve recognition, measurement, or disclosure
Consider need for representations about specific estimates.
Communication with Those Charged With Governance (Para. 38, A146-A148)
Consider matters to communicate, taking into account whether risks relate to:
- Estimation uncertainty
- Effects of complexity, subjectivity, or other inherent risk factors
Matters to communicate (Appendix 2):
- How management identified transactions requiring estimates
- Management's process for making estimates
- Risks of material misstatement
- Significant assumptions
- Indicators of possible management bias
- Significant difficulties encountered
- Significant qualitative aspects of accounting practices

Documentation Requirements (Para. 39)
Documentation Requirements
What to Document (Para. 39, A149-A152)
Include in audit documentation:
| Item | Description |
|---|---|
| (a) Understanding of entity and environment | Key elements of understanding, including internal control related to accounting estimates |
| (b) Linkage of procedures | Linkage of further audit procedures with assessed risks at assertion level, considering reasons (inherent risk or control risk) |
| (c) Response to estimation uncertainty | Auditor's response when management has not taken appropriate steps to understand and address estimation uncertainty |
| (d) Management bias indicators | Indicators of possible management bias and auditor's evaluation of implications |
| (e) Significant judgments | Significant judgments relating to determination of whether estimates and disclosures are reasonable or misstated |
Key takeaway: Documentation should demonstrate the auditor's professional judgment and the basis for conclusions reached.
