Materiality and Risk

Chapter 9


2/43


Learning Objective 1

Apply the concept of materiality

to the audit.


3/43


Materiality

It is a major consideration in determiningthe appropriate audit report to issue.


4/43


Materiality

The auditors responsibility is to determinewhether financial statements are

materially misstated.

If there is a material misstatement,the auditor will bring it to the clients

attention so that a correction can be made.

Steps in Applying Materiality

Step5


7/43



Make a preliminary judgment

about what amounts to

consider material.


8/43


Set Preliminary JudgmentAbout Materiality

This preliminary judgment is the maximum

amount by which the auditor believes thestatements could be misstated and still notaffect the decisions of reasonable users.

Auditors decide early in the auditthe combined amount of misstatementsof the financial statements that wouldbe considered material.


9/43


Factors Affecting Judgment

Materiality is a relative ratherthan an absolute concept.

Bases are needed forevaluating materiality.

Qualitative factors alsoaffect materiality.


10/43


Guidelines

Accounting and auditing standardsdo not provide specific materiality

guidelines to practitioners.

Professional judgment is to be usedat all times in setting and applyingmateriality guidelines.


11/43



Allocate preliminary materiality

to segments of the audit

during planning.


12/43


Allocate Preliminary JudgmentAbout 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.

SAS 107 (AU 312)


13/43



Use materiality to evaluate

audit findings.

16/43



Define risk in auditing.


17/43


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.


18/43


Risk and Evidence

Auditors gain an understanding of theclients business and industry andassess client business risk.

Auditors use the audit risk model to furtheridentify the potential for misstatements

and where they are most likely to occur.

Describe the audit risk model

and its components.


22/43


Audit Risk Model for Planning

PDR = AAR (IR CR)

PDR= Planned detection risk

AAR= Acceptable audit risk

IR= Inherent risk

CR= Control risk

where:


23/43



Consider the impact of

engagement risk on

acceptable audit risk.


24/43


Impact of Engagement Risk onAcceptable Audit Risk

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

Engagement risk closely relates to clientbusiness risk.


25/43


Factors Affecting AcceptableAudit Risk

The degree to which external usersrely on the statements

The likelihood that a client will havefinancial difficulties after theaudit report is issued

The auditors evaluation ofmanagements integrity

Methods Used to AssessAcceptable Audit RiskFactors


28/43



Consider the impact of several

factors on the assessment

of inherent risk.


29/43


Factors Affecting Inherent Risk

Nature of the clients business Results of previous audits Initial versus repeat engagement Related parties Nonroutine transactions Judgment required to correctly record

account balances and transactions Makeup of the population Factors related to fraudulent financial reporting Factors related to misappropriation of assets

The engagement may requiremore experienced staff

The engagement will be reviewedmore carefully than usual

Auditors can change the auditto respond to risks


33/43


Audit Risk for Segments

Both control risk and inherent risk aretypically set for each cycle, eachaccount, and often even each auditobjective, not for the overall audit.

Tolerable Misstatement, Risks,and Balance-related Audit

ObjectivesIt is common to assess inherent and control

risk for each balance-related audit objective

It is not common to allocate materialityto objectives


35/43


Measurement Limitations

One major limitation in the application of theaudit risk model is the difficulty of measuringthe components of the model.

Revising Risks and Evidence

The auditor must revise the originalassessment of the appropriate risk.

The auditor should consider the effectof the revision on evidence requirements,without the use of the audit risk model.
