HKSA 540 - Auditing Accounting Estimates

HKSA 540 (Revised) - Auditing Accounting Estimates and Related Disclosures

PART I: INTRODUCTION AND SCOPE

Scope of HKSA 540 (Revised)

HKSA 540 (Revised) deals with the auditor's responsibilities relating to accounting estimates and related disclosures in an audit of financial statements. It includes requirements and guidance that refer to, or expand on, how the following standards are to be applied in relation to accounting estimates and related disclosures:

HKSA 315 (Revised 2019) – Identifying and Assessing the Risks of Material Misstatement

HKSA 330 – The Auditor's Responses to Assessed Risks

HKSA 450 – Evaluation of Misstatements Identified during the Audit

HKSA 500 – Audit Evidence

Other relevant HKSAs

The standard also includes requirements and guidance on:

Evaluation of misstatements of accounting estimates and related disclosures

Indicators of possible management bias

Effective Date

This HKSA is effective for audits of financial statements for periods beginning on or after 15 December 2019.

PART II: NATURE OF ACCOUNTING ESTIMATES

Key Characteristics

Accounting estimates vary widely in nature and are required to be made by management when the monetary amounts cannot be directly observed. The measurement of these monetary amounts is subject to estimation uncertainty, which reflects inherent limitations in knowledge or data.

Key elements of accounting estimates:

Estimation uncertainty – Gives rise to inherent subjectivity and variation in measurement outcomes

Management judgment – Required in selecting and applying methods, assumptions, and data

Complexity – Can arise in measurement processes

Susceptibility to misstatement – Affected by complexity, subjectivity, or other inherent risk factors

Examples of Accounting Estimates (Para. A1)

Category	Examples
Asset-related	Inventory obsolescence, depreciation, valuation of infrastructure assets, impairment of long-lived assets
Financial instruments	Valuation of financial instruments, provision for expected credit losses
Liabilities	Outcome of pending litigation, warranty obligations, employee retirement benefits liabilities
Revenue	Revenue recognized for long-term contracts
Business combinations	Fair value of assets or liabilities acquired, determination of goodwill and intangible assets
Other	Share-based payments, non-monetary exchanges

Scalability (Para. 3, A7)

The degree to which an accounting estimate is subject to estimation uncertainty varies substantially. The nature, timing, and extent of audit procedures will vary accordingly:

Scenario	Expected Audit Effort
Very low estimation uncertainty, complexity, and subjectivity	Less extensive procedures
Very high estimation uncertainty, complexity, or subjectivity	Much more extensive procedures

PART III: KEY CONCEPTS OF THIS HKSA

Inherent Risk Factors (Para. 4, A8-A9)

HKSA 315 (Revised 2019) requires a separate assessment of inherent risk for identified risks of material misstatement at the assertion level. In the context of HKSA 540 (Revised), the susceptibility of an assertion to misstatement may be subject to or affected by:

Primary inherent risk factors:

Estimation uncertainty – Susceptibility to an inherent lack of precision in measurement

Complexity – Difficulty in understanding or applying methods, assumptions, or data

Subjectivity – Degree of judgment required in making the estimate

Additional inherent risk factors (from HKSA 315 (Revised 2019)):

Change in nature or circumstances of relevant financial statement items

Susceptibility to misstatement due to management bias or fraud risk factors

Uncertainty other than estimation uncertainty

The assessment of inherent risk depends on the degree to which these factors affect the likelihood or magnitude of misstatement, and varies on a scale referred to as the spectrum of inherent risk.

Control Risk (Para. 5-6, A10)

The auditor must consider:

Whether there are controls required to be identified by HKSA 315 (Revised 2019)

Whether to test the operating effectiveness of relevant controls

Key point: If the auditor does not plan to test the operating effectiveness of controls, or does not intend to rely on them, the assessment of control risk is such that the assessment of the risk of material misstatement is the same as the assessment of inherent risk.

Professional Skepticism (Para. 8, A11)

The exercise of professional skepticism in relation to accounting estimates is affected by the auditor's consideration of inherent risk factors. Its importance increases when:

Accounting estimates are subject to a greater degree of estimation uncertainty

Estimates are affected to a greater degree by complexity, subjectivity, or other inherent risk factors

There is greater susceptibility to misstatement due to management bias or fraud risk factors

Concept of "Reasonable" (Para. 9, A12-A13)

For purposes of this HKSA, "reasonable in the context of the applicable financial reporting framework" means that the relevant requirements have been applied appropriately, including those that address:

Making the accounting estimate – Including selection of method, assumptions, and data

Selection of management's point estimate

Disclosures – About how the estimate was developed and explaining nature, extent, and sources of estimation uncertainty

PART IV: DEFINITIONS (Para. 12)

Term	Definition	Ref.
Accounting estimate	A monetary amount for which the measurement, in accordance with the requirements of the applicable financial reporting framework, is subject to estimation uncertainty	A14
Auditor's point estimate or auditor's range	An amount, or range of amounts, respectively, developed by the auditor in evaluating management's point estimate	A15
Estimation uncertainty	Susceptibility to an inherent lack of precision in measurement	A16
Management bias	A lack of neutrality by management in the preparation of information	A17
Management's point estimate	The amount selected by management for recognition or disclosure in the financial statements as an accounting estimate	-
Outcome of an accounting estimate	The actual monetary amount that results from the resolution of the transaction(s), event(s) or condition(s) addressed by an accounting estimate	A18

Additional Clarifications on Definitions

Accounting Estimate (A14):

May be related to classes of transactions or account balances recognized or disclosed in the financial statements

Also includes monetary amounts included in disclosures or used to make judgments about recognition or disclosure

Auditor's Point Estimate or Range (A15):

May be used to evaluate an accounting estimate directly (e.g., impairment provision) or indirectly (e.g., amount used as a significant assumption)

Similar approach may be taken for non-monetary items (e.g., estimated useful life of an asset)

Estimation Uncertainty (A16):

Not all accounting estimates are subject to a high degree of estimation uncertainty

Example: Securities quoted on an active market may have low estimation uncertainty

However, adjustments may be needed for large holdings or restrictions on marketability

Management Bias (A17):

Financial reporting frameworks often call for neutrality (freedom from bias)

Estimation uncertainty gives rise to subjectivity, which creates opportunity for management bias

Susceptibility to management bias increases with the extent of subjectivity

Outcome of an Accounting Estimate (A18):

Some accounting estimates do not have an outcome relevant for the auditor's work

Example: Fair value estimates based on market participant perceptions at a point in time

5.2 Identifying and Assessing the Risks of Material Misstatement (Para. 16-17)

Requirements for Risk Identification and Assessment (Para. 16)

In identifying and assessing risks of material misstatement relating to an accounting estimate at the assertion level, the auditor shall take into account:

(a) The degree to which the accounting estimate is subject to estimation uncertainty (A72-A75):

Considerations include:

Whether the applicable financial reporting framework requires:

Use of a method with inherently high estimation uncertainty

Use of assumptions with inherently high estimation uncertainty

Disclosures about estimation uncertainty

The business environment (e.g., market turmoil)

Whether management can make precise and reliable predictions

Important: The size of the amount recognized or disclosed is not, in itself, an indicator of susceptibility to misstatement.

*(i) Selection and application of method, assumptions, and data*

Complexity affecting method (A76):

Need for specialized skills or knowledge

Nature of measurement basis required

Procedures shall be designed and performed in a manner that is not biased towards obtaining corroborative evidence or excluding contradictory evidence

Tests of Controls (Para. 19-20, A85-A90)

The auditor shall design and perform tests of controls if:

(a) The assessment of risks of material misstatement includes an expectation that controls are operating effectively; OR

(b) Substantive procedures alone cannot provide sufficient appropriate audit evidence

For significant risks:

If the auditor plans to rely on controls, tests of controls in the current period are required

If the approach consists only of substantive procedures, those procedures shall include tests of details

Events Approach (Para. 21, A91-A93)

When using this approach, the auditor shall evaluate whether such audit evidence is sufficient and appropriate, taking into account that changes in circumstances and other relevant conditions between the event and measurement date may affect relevance.

When this approach may be appropriate:

Simple bonus accrual paid shortly after period end

When this approach may not be appropriate:

Conditions or events develop only over an extended period

Fair value estimates (information after period-end may not reflect conditions at balance sheet date)

Testing How Management Made the Accounting Estimate (Para. 22-27)

When this approach may be appropriate (A94):

Prior period review suggests current period process is appropriate

Estimate based on large population of similar items

Framework specifies how management should make the estimate

Estimate derived from routine processing of data

(e) Whether integrity of significant assumptions and data has been maintained in applying the method (A101)

Significant Assumptions (Para. 24, A102-A105)

The auditor's procedures shall address:

(a) Whether significant assumptions are appropriate (A95, A102-A103):

Management's rationale for selection

Appropriateness given nature of estimate, framework, and circumstances

Whether changes from prior periods are appropriate

(b) Whether judgments give rise to indicators of possible management bias (A96)

(c) Whether significant assumptions are consistent:

With each other

With those used in other accounting estimates

With related assumptions used in other areas of the entity's business activities

(d) When applicable, whether management has the intent and ability to carry out specific courses of action (A105)

Data (Para. 25, A106-A108)

Selecting an appropriate point estimate

Developing related disclosures about estimation uncertainty

When management has not taken appropriate steps (Para. 27, A115-A117):

The auditor shall:

Request management to perform additional procedures

If management's response is insufficient, develop an auditor's point estimate or range (to the extent practicable)

Evaluate whether a deficiency in internal control exists

Developing an Auditor's Point Estimate or Range (Para. 28-29, A118-A125)

When developing a point estimate or range (Para. 28, A118-A123):

The auditor shall evaluate whether judgments and decisions made by management in making accounting estimates, even if individually reasonable, are indicators of possible management bias.

Key points:

When indicators are identified, evaluate implications for the audit

Where there is intention to mislead, management bias is fraudulent in nature

Examples of indicators of possible management bias (A133-A136):

Changes in an accounting estimate when method has not changed

Use of assumptions at one end of a reasonable range

Selection or changes in significant assumptions resulting in a more favorable outcome

Sensitivity analysis showing material impact but no disclosure

Bias in estimates may be difficult to detect at the individual level but may be apparent when considered in aggregate

5.6 Overall Evaluation Based on Audit Procedures Performed (Para. 33-36)
