Materiality
What is materiality?
Materiality means how important an error is in the financial statements.
How many components make up audit risk?
Three components.
What is the risk of material misstatement (RMM)?
The risk that the financial statements contain material errors before the audit.
When are risk assessment procedures performed?
At the planning stage of the auditing
Scenario:
A company reports profit before tax of $2,000,000. During the audit, the auditor finds an error of $8,000 in office expenses.
Question:
Is the misstatement likely to be material?
Using 5% of profit before tax, materiality would be approximately $100,000. The $8,000 error is far below this threshold and is therefore unlikely to be material, assuming no qualitative factors are involved.
What two main factors affect materiality?
Size of the misstatement (quantitative)
Nature of the misstatement (qualitative)
Which audit risk can the auditor control?
Detection risk.
What increases control risk?
Weak or ineffective internal controls, such as lack of segregation of duties.
Name the three main risk assessment procedures.
Inquiries, analytical procedures, and observation and inspection.
Scenario:
The auditor assesses RMM at 30%.
Control risk is assessed as 50%.
Required:
Calculate the implied inherent risk.
Solution:
IR=RMMCRIR = \frac{RMM}{CR}IR=CRRMM IR=0.300.50=0.60IR = \frac{0.30}{0.50} = 0.60IR=0.500.30=0.60
✅ Inherent Risk = 60%
The business has moderately high inherent risk.
Can a small misstatement be material? Explain briefly.
Yes. A small misstatement can be material if it involves fraud, illegal acts, or breaches of regulations or contracts.
State the audit risk model.
Audit risk = Inherent risk × Control risk × Detection risk.
State the formula for risk of material misstatement.
Risk of Material Misstatement = Inherent Risk × Control Risk.
What is the purpose of inquiries in risk assessment?
To obtain information from management and employees about the business, controls, and potential risks.
Scenario:
An auditor performs very limited audit testing due to time pressure, even though the client operates in a high-risk industry.
Question:
Which type of audit risk is increased?
Detection risk is increased because insufficient audit procedures increase the risk that material misstatements will not be detected.
Name one benchmark used to calculate materiality under ISA 320.
5%–10% or 0.5%–1% or 1%–2%
Why is detection risk the only risk controlled by the auditor?
Because auditors cannot change the nature of the business or internal controls, but they can adjust the nature, timing, and extent of audit procedures.
Relationship Between Risks
High inherent and control risk → ?????
Low detection risk required
Comparing current year results with prior years can be an example for which type of risk assessment procedure?
Analytical procedures
Scenario:
The auditor wants to keep audit risk at 5%.
Given:
Audit Risk (AR) = 5% (0.05)
Inherent Risk (IR) = 80% (0.80)
Control Risk (CR) = 50% (0.50)
Required:
Calculate Detection Risk.
✅ Detection risk = 12.5%
Which materiality benchmark is used when assets are more important than profit?
1% – 2% of Total Assets
Differentiate between inherent risk and control risk.
Inherent risk arises from the nature of the business or transactions, while control risk arises from weaknesses in the internal control system.
Relationship Between Risks
Higher detection risk acceptable
Explain the link between risk assessment procedures and audit risk.
Risk assessment procedures help identify risks of material misstatement, enabling auditors to adjust detection risk and reduce overall audit risk.
Scenario:
A start-up company:
Has rapid growth
Uses aggressive revenue recognition
Has inexperienced accounting staff
Question:
Is inherent risk low, medium, or high?
The inherent risk is high due to the complexity of transactions, rapid growth, and increased susceptibility to error.
