The Audit Risk Model and Misstatement Analysis

What is the definition of audit risk?

The risk that the auditor unknowingly fails to appropriately modify the opinion on financial statements that are materially misstated.

Why do auditors aim to keep audit risk at a very low level?

To avoid being sued by lawyers representing users of the financial statements.

Audit risk is initially assessed during which phase of the audit?

The assessed risk and response phase.

What level of assurance do auditors provide in their report regarding the absence of material misstatements?

Reasonable assurance.

Why is it impossible for an auditor to provide absolute assurance?

There is always a risk that the client hides information or the auditor uses the wrong procedure.

Definition: Material Misstatement

An omission or misstatement of accounting information that could have changed a user's decision.

Misstatements resulting from unintentional mistakes are classified as _____.

Errors

Misstatements resulting from an intentional act of deceit are classified as _____.

Fraud

Name three categories used to classify misstatements.

Factual, judgmental, and projected misstatements.

Definition: Factual Misstatements

Misstatements about which there is no doubt, such as an objective recording error.

Example: A copier purchased for $\$500$ is recorded as $\$5,000$. What type of misstatement is this?

A factual misstatement.

Definition: Judgmental Misstatements

Misstatements arising from differences in judgment between management and the auditor regarding accounting estimates or policies.

An auditor believes the allowance for accounts receivable should be $4\%$, but management insists on $3\%$. This is a _____ misstatement.

Judgmental

Definition: Projected Misstatements

The auditor's best estimate of misstatements in a population based on a sample.

If an auditor finds a $10\%$ misstatement in a sample and assumes the same rate applies to the whole population, what type of misstatement is being calculated?

A projected misstatement.

What is the basic Audit Risk formula?

$$Audit\ Risk = Risk\ of\ Material\ Misstatement \times Detection\ Risk$$

What two components make up the Risk of Material Misstatement ($RMM$)?

Inherent Risk and Control Risk.

The Expanded Audit Risk Formula is: $AR =$ _____.

$$Inherent\ Risk \times Control\ Risk \times Detection\ Risk$$

In what two ways can the components of the audit risk formula be assessed?

Quantitatively (as a percentage) or non-quantitatively (high, medium, low).

The Risk of Material Misstatement ($RMM$) is the product of which two factors?

The likelihood of a misstatement occurring and the magnitude (materiality) of that misstatement.

Definition: Inherent Risk

The susceptibility of an assertion to a material misstatement before considering any related internal controls.

List the five qualitative factors that increase inherent risk.

Complexity, subjectivity, change, uncertainty, and susceptibility to management bias.

Inherent Risk Factor: Complexity

Definition: Risks associated with difficult calculations or intricate business processes, such as derivatives.

Inherent Risk Factor: Subjectivity

Definition: Risks arising from gray areas where multiple measurement criteria or valuation models exist.

Inherent Risk Factor: Change

Definition: Risks resulting from new accounting pronouncements or moving into new business locations.

Inherent Risk Factor: Uncertainty

Definition: Risks related to items like pending litigation or contingent liabilities where outcomes are not yet known.

Inherent Risk Factor: Management Bias

Definition: Risks occurring when management has the intent or opportunity to manipulate financial numbers, such as in related party transactions.

The scale used to look at the combination of likelihood and magnitude of inherent risk is called the _____.

Spectrum of inherent risk

Why does cash have high inherent risk?

It is easily susceptible to theft compared to other assets like real estate.

Why do high-volume transactions increase inherent risk?

They provide more opportunities to hide misstatements that auditors might miss.

Accounts like prepaid expenses are typically assessed as having _____ inherent risk.

Low

Definition: Control Risk

The risk that a material misstatement will not be prevented or detected on a timely basis by the client's internal controls.

Under what condition does an auditor assess control risk as low?

When the auditor plans to rely on the controls and subsequently tests their operating effectiveness.

List three situations where an auditor would assess control risk as high.

Controls are absent, controls are poorly implemented, or it is more efficient to perform substantive testing only.

Which two components of audit risk exist independently of the audit and cannot be changed by the auditor's procedures?

Inherent risk and control risk.

True or False: If an auditor finds an account is more complex than initially thought, they can change the actual inherent risk of the client.

False (The auditor only changes their assessment of the risk, not the risk itself).

Definition: Detection Risk

The risk that the auditor's procedures will fail to detect a material misstatement that exists in a relevant assertion.

Which component of the audit risk formula does the auditor have direct control over?

Detection risk.

Detection risk is a function of the effectiveness of _____ and how they are applied by the auditor.

Audit procedures

Why will there always be some level of detection risk?

Auditors use sampling rather than testing $100\%$ of the population, and auditors are prone to human error.

What is the relationship between the Risk of Material Misstatement ($RMM$) and Detection Risk ($DR$)?

There is an inverse relationship.

If the Risk of Material Misstatement is high, the auditor should set detection risk to _____.

Low

If the Risk of Material Misstatement is low, the auditor can accept a _____ detection risk.

High

The auditor controls detection risk by changing the 'NET' of substantive procedures. What does 'NET' stand for?

Nature, Extent, and Timing.

To achieve a low detection risk, how should the auditor change the nature of procedures?

Move from less effective to more effective/persuasive procedures.

To achieve a low detection risk, how should the auditor change the extent of procedures?

Increase the sample size and look at more items.

To achieve a low detection risk, how should the auditor change the timing of procedures?

Perform testing at year-end rather than at an interim date.

A high detection risk allows the auditor to use _____ persuasive evidence and _____ sample sizes.

Less; smaller

True or False: If inherent risk and control risk are both low, the auditor can choose to perform zero substantive procedures.

False (Substantive procedures are always necessary for each relevant assertion of significant accounts).

What is the relationship between Detection Risk ($DR$) and the amount of assurance needed from substantive procedures?

There is an inverse relationship (Lower $DR$ requires more assurance).

What is the relationship between audit risk and materiality?

There is an inverse relationship.

Why is the relationship between audit risk and materiality inverse?

The risk of a very large (material) mistake is generally lower than the risk of a small misstatement.

How can the detection risk formula be rewritten to show its dependence on other risks?

$$Detection\ Risk = \frac{Audit\ Risk}{Inherent\ Risk \times Control\ Risk}$$

If the auditor assesses $RMM$ as high, does this result in more or less audit work?

More audit work (to achieve a low detection risk).

When an auditor 'stands back' during the audit, what are they assessing regarding material classes of transactions?

Whether they have provided enough coverage to accounts that may lack significant assertions but are still material.

In the context of misstatements, what represents 'the elephant in the room' vs. 'a needle in a haystack'?

Material misstatements are 'elephants' (easier to detect) while small misstatements are 'needles' (harder to detect).

What happens to the $RMM$ assessment if the auditor discovers controls are not operating effectively during testing?

The auditor must increase the assessment of control risk and, consequently, the risk of material misstatement.

Audit risk is the risk of issuing an _____ opinion when the financial statements are materially misstated.

Unmodified (or unqualified)

Which factor of inherent risk involves transactions with related parties?

Susceptibility to management bias.

Which factor of inherent risk involves the use of complex processes like derivatives?

Complexity

If an auditor decides to test solely through substantive procedures, at what level is control risk set?

Maximum (High)

In non-quantitative terms, how do examiners most often express the components of audit risk?

Either 'High' or 'Low'.

What is the ultimate purpose of assessing inherent and control risk?

To help the auditor determine where material misstatements are most likely to occur (identifying $RMM$).

If an auditor misinterprets audit results, which risk component is specifically impacted?

Detection risk.

Why does a decline in the overall economy increase inherent risk?

It creates pressure on management to manipulate numbers to meet goals or bonuses.
