1 Materiality and Risk Chapter 9 9-1

2 Learning Objective 1 Apply the concept of materiality to the audit. 9-2

3 Materiality The auditor s responsibility is to determine 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. 9-3

4 Steps in Applying Materiality Step 1 Step 2 Set preliminary judgment about materiality. Allocate preliminary judgment about materiality to segments. Planning extent of tests 9-4

5 Steps in Applying Materiality Step 3 Estimate total misstatement in segment. Step 4 Step 5 Estimate the combined misstatement. Compare combined estimate with judgment about materiality. Evaluating results 9-5

6 Learning Objective 2 Make a preliminary judgment about what amounts to consider material. 9-6

7 Set Preliminary Judgment about Materiality Ideally, auditors decide early in the audit the combined amount of misstatements of the financial statements that would be considered material. This preliminary judgment is the maximum amount by which the auditor believes the statements could be misstated and still not affect the decisions of reasonable users. 9-7

8 Factors Affecting Judgment Materiality is a relative rather than an absolute concept. Bases are needed for evaluating materiality. Qualitative factors also affect materiality. 9-8

9 Guidelines Accounting and auditing standards do not provide specific materiality guidelines to practitioners. Professional judgment is to be used at all times in setting and applying materiality guidelines. 9-9

10 Learning Objective 3 Allocate preliminary materiality to segments of the audit during planning. 9-10

11 Allocate Preliminary Judgment About Materiality to Segments This is necessary because evidence is accumulated by segments rather than for the financial statements as a whole. Most practitioners allocate materiality to balance sheet accounts. SAS 39 (AU 350) 9-11

12 Learning Objective 4 Use materiality to evaluate audit findings. 9-12

15 Learning Objective 5 Define risk in auditing. 9-15

16 Risk Auditors accept some level of risk in performing the audit. An effective auditor recognizes that risks exist, are difficult to measure, and require careful thought to respond. Responding to risks properly is critical to achieving a high-quality audit. 9-16

17 Risk and Evidence Auditors gain an understanding of the client s business and industry and assess client business risk. Auditors use the audit risk model to further identify the potential for misstatements and where they are most likely to occur. 9-17

18 Illustration of Differing Evidence Among Cycles Sales and collection cycle Acquisition and payment cycle Inherent A Medium High Low risk Control B Medium Low Low risk Acceptable C Low Low Low audit risk Planned D Medium Medium High detection risk Payroll and personnel cycle 9-18

19 Illustration of Differing Evidence Among Cycles Inventory and warehousing cycle Inherent A High Low risk Control B High Medium risk Acceptable C Low Low audit risk Planned D Low Medium detection risk Capital acquisition and repayment cycle 9-19

20 Learning Objective 6 Describe the audit risk model and its components. 9-20

21 Audit Risk Model for Planning PDR = AAR (IR CR) PDR = Planned detection risk AAR = Acceptable audit risk IR = Inherent risk CR = Control risk 9-21

22 Learning Objective 7 Consider the impact of engagement risk on acceptable audit risk. 9-22

23 Impact of Engagement Risk on Acceptable Audit Risk Auditors decide engagement risk and use that risk to modify acceptable audit risk. Engagement risk closely relates to client business risk. 9-23

24 Factors Affecting Acceptable Audit Risk The degree to which external users rely on the statements The likelihood that a client will have financial difficulties after the audit report is issued The auditor s evaluation of management s integrity 9-24

25 Making the Acceptable Audit Risk Decision Factors External users reliance on financial statements Methods used to assess acceptable audit risk Examine financial statements. Read minutes of the board. Examine form 10K. Discuss financing plans with management. 9-25

26 Making the Acceptable Audit Risk Decision Factors Likelihood of financial difficulties Management integrity Methods used to assess acceptable audit risk Analyze financial statements for difficulties using ratios. Examine inflows and outflows of cash flow statements. See Chapter 8 for client acceptance and continuance. 9-26

27 Learning Objective 8 Consider the impact of several factors on the assessment of inherit risk. 9-27

28 Factors Affecting Inherent Risk Nature of the client s 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 9-28

29 Learning Objective 9 Discuss the relationship of risks to audit evidence. 9-29

30 Relationship of Risk Factors, Risk, and Evidence Acceptable audit risk D D I Factors influencing risks Inherent risk I Planned detection risk I Planned audit evidence I D Control risk D = Direct relationship; I = Inverse relationship 9-30

31 Relationship of Risk Factors, Risk, and Evidence Auditors can change the audit to respond to risks. The engagement may require more experienced staff. The engagement will be reviewed more carefully than usual. 9-31

32 Audit Risk for Segments Both control risk and inherent risk are typically set for each cycle, each account, and often even each audit objective, not for the overall audit. 9-32

33 Relating Risk of Fraud to Risk Model Components The risk of fraud can be assessed for the entire audit or by cycle, account, and objective. Specific response could include revising assessments of acceptable audit risk, inherent risk, and control risk. 9-33

34 Tolerable Misstatement, Risks, and Balance-related Objectives It is common to assess inherent and control risk for each balance-related audit objective. It is not common to allocate materiality to objectives. 9-34

35 Measurement Limitations One major limitation in the application of the audit risk model is the difficulty of measuring the components of the model. 9-35

36 Relationships of Risk to Evidence Situation Acceptable audit risk Inherent risk Control risk Planned detection risk Amount of evidence required 1 High Low Low High Low 2 Low Low Low Medium Medium 3 Low High High Low High 4 Medium Medium Medium Medium Medium 5 High Low Medium Medium Medium 9-36

37 Tests of Details of Balances Evidence Planning Worksheet Auditors develop various types of worksheets to aid in relating the considerations affecting audit evidence to the appropriate evidence to accumulate. 9-37

38 Learning Objective 10 Discuss how materiality and risk are related and integrated into the audit process. 9-38

39 Tolerable Misstatements, Risk, and Planned Evidence Acceptable audit risk D D I Inherent risk Control risk I Planned detection risk I I Planned audit evidence D I Tolerable misstatement D = Direct relationship; I = Inverse relationship 9-39

40 Evaluating Results AcAR = IR CR AcDR AcAR = Achieved audit risk IR = Inherent risk CR = Control risk AcDR = Achieved detection risk 9-40

41 Audit Risk Models for Planning Evidence and Evaluating Results Acceptable audit risk Compare Achieved audit risk D D Inherent risk Control risk Substantive audit evidence D Achieved detection risk D = Direct relationship I = Inverse relationship I 9-41

42 Revising Risks and Evidence The audit risk model is primarily a planning model and is therefore of limited use in evaluating results. Great care must be used in revising the risk factors when the actual results are not as favorable as planned. 9-42
