Materiality and Risk

Chapter 8

8 - 2©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Learning Objective 1

Apply the concept of

materiality to the audit.

8 - 3©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Materiality

The auditor’s responsibility is todetermine whether financial

statements are materially misstated.

If there is a material misstatement,the auditor will bring it to the client’s

attention so that a correction can be made.

Steps in ApplyingMateriality

Step1

Set preliminaryjudgment about

materiality.Planning

extentof tests

Step2

Allocate preliminaryjudgment about

materialityto segments.

Steps in ApplyingMateriality

Step3

Estimate totalmisstatement in segment.

Evaluatingresults

Step4

Estimate thecombined misstatement.

Compare combinedestimate with judgment

about materiality.

Step5

Learning Objective 2

Make a preliminary judgment

about what amounts to

consider material.

8 - 7©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Set Preliminary Judgment

This preliminary judgment is the maximumamount by which the auditor believes thestatements could be misstated and still notaffect the decisions of reasonable users.

Ideally, auditors decide early in the auditthe combined amount of misstatementsof the financial statements that would

be considered material.

Factors Affecting Judgment

Materiality is a relative ratherthan an absolute concept.

Bases are needed forevaluating materiality.

Qualitative factors alsoaffect materiality.

8 - 9©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Learning Objective 3

Allocate preliminary materiality

to segments of the audit

during planning.

8 - 10©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Allocate Preliminary Judgment About Materiality to Segments

This is necessary because evidence isaccumulated by segments rather than

for the financial statements as a whole.

Most practitioners allocate materialityto balance sheet accounts.

Learning Objective 4

Use materiality to evaluate

audit findings.

Learning Objective 5

Define risk in auditing.

8 - 15©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Risk

Auditors accept some level of riskin performing the audit.

An effective auditor recognizes thatrisks exist, are difficult to measure,

and require careful thought to respond.

Responding to risks properly is criticalto achieving a high-quality audit.

8 - 16©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Risk and Evidence

Auditors gain an understanding of theclient’s business and industry and

assess client business risk.

Auditors use the audit risk model to furtheridentify the potential for misstatementsand where they are most likely to occur.

Learning Objective 6

Describe the audit risk

model and its components.

8 - 20©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Audit Risk Modelfor Planning

PDR = AAR ÷ (IR × CR)

PDR = Planned detection risk

AAR = Acceptable audit risk

IR = Inherent risk

CR = Control risk

8 - 21©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Learning Objective 7

Consider the impact of

engagement risk on

acceptable audit risk.

8 - 22©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Impact of Engagement Riskon Acceptable Audit Risk

Auditors decide engagement risk and usethat risk to modify acceptable audit risk.

Engagement risk closely relates toclient business risk.

8 - 23©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Factors AffectingAcceptable Audit Risk

The degree of which external usersrely on the statements

The degree of which external usersrely on the statements

The likelihood that a client will havefinancial difficulties after the

audit report is issued

8 - 24©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Factors AffectingAcceptable Audit Risk

The auditor’s evaluation of management’s integrity

8 - 25©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Making the AcceptableAudit Risk Decision

External usersreliance onfinancial

statements

• Examine financial statements.• Read minutes of the board.• Examine form 10K.• Discuss financing plans with management.

Methods to Assess RiskFactors

Methods to Assess Risk

Likelihoodof financialdifficulties

• Analyze financial statements for difficulties using ratios.• Examine inflows and outflows

of cash flow statements.

Factors

Managementintegrity

• See Chapter 7 for client acceptance and continuance.

Learning Objective 8

Consider the impact of several

factors on the assessment

of inherent risk.

8 - 28©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Major Factors WhenAssessing Inherent Risk

• Nature of the client’s business • Results of previous audits• Initial versus repeat engagement• Related parties• Nonroutine transactions• Judgment – correctly record account

balances and transactions• Makeup of the population

8 - 29©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Learning Objective 9

Consider information

gathered to assess the

likelihood of fraud.

8 - 30©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Assessing Risks of Fraud

Three conditions are generally present.

1. Incentives/Pressures

2. Opportunities

3. Attitudes/Rationalization

8 - 31©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Examples of Risks Factorsfor Fraudulent Reporting

1. Incentives/Pressures

Financial stability or profitability is threatened byeconomic, industry, or entity operating conditions.

Excessive pressure exists for managementto meet debt requirements.

Personal net worth is materially threatened.

8 - 32©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Examples of Risks Factorsfor Fraudulent Reporting

2. Opportunities

There are significant accounting estimatesthat are difficult to verify.

There is ineffective oversight overfinancial reporting.

High turnover or ineffective accounting internalaudit, or information technology staff exists.

8 - 33©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Examples of Risks Factorsfor Fraudulent Reporting

3. Attitudes/Rationalization

Inappropriate or inefficient communicationand support of the entity’s values is evident.

A history of violations of laws is known.

Management has a practice of making overlyaggressive or unrealistic forecasts.

8 - 34©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Responding to theRisk of Fraud

Design and perform audit proceduresto address identified fraud risk.

Change the overall conduct of the auditto respond to identified fraud risk.

Perform procedures to address the riskof management override of controls.

Learning Objective 10

Discuss the relationship

of risks to audit evidence.

Changing the Audit inResponse to Risk

The engagement may requiremore experienced staff.

The engagement will be reviewedmore carefully than usual.

8 - 38©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Audit Risk for Segments

Both control risk and inherent riskare typically set for each cycle,each account, and often eveneach audit objective, not for

the overall audit.

8 - 39©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Relating Risk of Fraud toRisk Model Components

The risk of fraud can be assessedfor the entire audit or by cycle,

account, and objective.

Specific response could includerevising assessments of acceptable

audit risk, inherent risk, and control risk.

8 - 40©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Tolerable Misstatement, Risks,and Balance-related Objectives

It is common to assess inherent and controlrisk for each balance-related audit objective.

It is not common to allocatemateriality to objectives.

8 - 41©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Measurement Limitations

One major limitation in the applicationof the audit risk model is the difficulty

of measuring the components of the model.

Audit Risk Model forEvaluating Results

AcAR = IR × CR × AcDR

AcAR = Achieved audit risk

AcDR = Achieved detection risk

IR = Inherent risk

CR = Control risk

8 - 47©2003 Prentice Hall Business Publishing, Essentials of Auditing 1/e, Arens/Elder/Beasley

Revising Risksand Evidence

The audit risk model is primarily aplanning model and is therefore oflimited use in evaluating results.

Great care must be used in revisingthe risk factors when the actual results

are not as favorable as planned.
