Audit Scope & Account Selection

Select Account / Assertion: Cash & Cash Equivalents Accounts Receivable Inventory Property, Plant & Equipment Revenue

Accounts Receivable: Amounts owed by customers.

Key Risks: Overstatement, valuation of bad debts, cut-off.

ISA 540 Consideration: Bad debt provisions involve accounting estimates with measurement uncertainty.

Inventory: Goods held for sale or production.

Key Risks: Valuation, obsolescence, existence, completeness.

ISA 501 Consideration: Physical inventory observation and valuation testing are critical procedures.

Property, Plant & Equipment: Long-term tangible assets.

Key Risks: Valuation, depreciation calculations, existence, rights and obligations.

ISA 540 Consideration: Depreciation involves estimates of useful life and residual value.

Revenue: Income from business operations.

Key Risks: Recognition timing, cut-off, accuracy, completeness.

ISA 240 Consideration: Revenue recognition is a common area for fraud risk and manipulation.

Overall Audit Risk Tolerance (Professional Judgment):

Medium

Based on professional judgment considering client, users, and regulatory environment

ISA 200: Overall Audit Risk Considerations

Audit Risk is the risk that the auditor expresses an inappropriate audit opinion when the financial statements are materially misstated. Consider these professional judgment factors:

Lower Risk Tolerance

Consider when:

• Public company with regulatory scrutiny
• Complex transactions and estimates
• History of material misstatements
• Going concern issues identified

Medium Risk Tolerance

Consider when:

• Standard private company audit
• Moderate business complexity
• Average control environment
• No significant prior audit issues

Higher Risk Tolerance

Consider when:

• Limited scope engagement
• Strong historical audit evidence
• Excellent control environment
• Well-established entity with consistent results

Professional Judgment Required

Always apply:

• Professional skepticism
• Consideration of financial statement users
• Regulatory requirements
• Materiality considerations

ISA 315 Inherent Risk Assessment

Assess susceptibility to material misstatement before considering controls

ISA 315 Inherent Risk Factors

Inherent risk is the susceptibility of an assertion to material misstatement before considering controls. Assess based on:

• Complexity: Transactions requiring specialized knowledge
• Estimation uncertainty: Accounting estimates with high measurement uncertainty
• Susceptibility to fraud: Assets vulnerable to misappropriation
• Judgment involved: Areas requiring significant management judgment
• Recent changes: New accounting requirements or business changes

Professional Judgment Required: Inherent risk assessment requires consideration of both likelihood and potential magnitude of misstatement, not mathematical calculation.

ISA 315 Control Risk Assessment

Evaluate control design and implementation for selected account

ISA 315 Control Risk Assessment

Control risk is the risk that a material misstatement will not be prevented or detected by the entity's internal controls.

Key Principles:

• Evaluate both design and implementation of controls
• Ineffective key controls relevant to significant assertions elevate overall control risk
• Consider both entity-level and transaction-level controls
• Assess whether controls operate consistently throughout the period

ISA 315 Requirement: When the auditor intends to rely on controls, tests of controls must be performed.

ISA Risk Assessment Explanation

Step 1: Inherent Risk Assessment (ISA 315)

IR assessed qualitatively based on susceptibility to misstatement considering:

• Complexity of transactions
• Estimation uncertainty
• Susceptibility to fraud
• Degree of judgment involved

Current assessment: MODERATE based on moderate likelihood and magnitude

Step 2: Control Risk Assessment (ISA 315)

CR assessed based on evaluation of control design and implementation effectiveness:

• Effectiveness of key controls for significant assertions
• Consistency of control operation
• Weakest link principle for key controls

Current assessment: MODERATE based on control evaluation

Step 3: Risk of Material Misstatement (ISA 200)

RMM is a conceptual combination of inherent risk and control risk:

RMM

Current assessment: MODERATE RMM (Moderate IR + Moderate CR)

Step 4: Detection Risk Determination (ISA 200)

Detection Risk is determined by the inverse relationship with RMM:

Higher RMM → Lower acceptable Detection Risk

Lower RMM → Higher acceptable Detection Risk

Based on MODERATE RMM: MODERATE DETECTION RISK is acceptable

ISA 330 Audit Response & Strategy

Recommended Audit Approach (ISA 330)

Based on MODERATE RMM and MODERATE acceptable detection risk, implement a BALANCED AUDIT APPROACH combining control testing and substantive procedures.

Nature of Procedures (ISA 330.6)

Combine tests of controls with substantive procedures. Test operating effectiveness of key controls while performing substantive analytical procedures and tests of details for higher risk assertions.

Timing of Procedures (ISA 330.20)

Consider interim testing of controls with update procedures at period-end. Perform substantive procedures closer to period-end, particularly for higher risk areas.

Extent of Procedures (ISA 330.7)

Apply moderate sample sizes with emphasis on higher risk transactions. Increase extent of testing for areas with identified control deficiencies or higher inherent risk.

Control Reliance Decision

Moderate reliance on controls after testing operating effectiveness. Supplement with substantive procedures for significant assertions.

Key Audit Procedures to Consider

• Test operating effectiveness of identified key controls
• Perform substantive analytical procedures on material accounts
• Execute tests of details for higher risk transactions
• Consider confirmations for significant balances
• Test cut-off procedures around period-end
• Document risk assessment and responses thoroughly
