Role of all Audit Tests in the Sales and Collection Cycle Sales Accounts Receivable Cash in Bank Sales transactions Cash receipts transactions Audited by TOC,STOT, and AP Audited by TOC, STOT, and AP Ending balance Ending balance Audited by AP and TDB TOC+STOT+AP+TDB = Sufficient competent evidence per GAAS

7. Learning Objective 2 Select the appropriate types of audit tests.

10. Audit Assurance at Different Levels of Internal Control Effectiveness C3 Acceptable assurance Audit assurance from control risk assessment and tests of control C2 Audit assurance from substantive tests AUDIT ASSURANCE C1 No assurance A C B INTERNAL CONTROL EFFECTIVENESS Weak control Strong control Reliance on controls: C3 – None, C2 – Some, C1 – Maximum

11. Learning Objective 3 Understand how information technology affects audit testing.

12. Impact of Information Technology on Audit Testing SAS 80 (AU 326) and SAS 94 (AU 319) provide guidance for auditors of entities that transmit, process, maintain, or access significant information electronically.

13. Impact of Information Technology on Audit Testing Computer assisted audit techniques may be used to test automated controls or data. Reports produced by IT may be used to test the effectiveness of IT general controls. Program change controls Access controls

14. Learning Objective 4 Understand the concept of evidence mix and how it should be varied in different circumstances.

15. Variations in Evidence Mix Procedures to Obtain an Understanding of Internal Control Tests of Controls Audit 1 E E Audit 2 M M Audit 3 M N Audit 4 M M Amount of testing: Extensive, Medium, Small, None

16. Variations in Evidence Mix Substantive Tests of Transactions Analytical Procedures Tests of Details of Balances Audit 1 S E S Audit 2 M E M Audit 3 E M E Audit 4 E E E Amount of testing: Extensive, Medium, Small, None

17. Learning Objective 5 Design an audit program.

18. Audit Program Part 1: Tests of controls and substantive tests of transactions Part 2: Analytical procedures Part 3: Tests of details and balances

19. Audit Procedures • Apply the transaction-related audit objectives • to the class of transactions being tested. 2. Identify key controls that should reduce control risk for each audit objective. 3. Develop appropriate tests of controls. 4. Design substantive tests of transactions.

20. Methodology for Designing Controls and Substantive Tests Design tests of controls and substantive tests of transactions to meet transaction-related audit objectives. Perform procedures to understand internal control. Assess control risk. Audit procedures Sample size Evaluate cost-benefit of testing controls. Items to select Timing

21. Four-Step Approach to Designing Control and Substantive Tests Apply transaction- related audit objectives to a class of transactions (Step 1). Identify key controls and make an assessment of control risk (Step 2). Design substantive tests of transactions (Step 4). Design tests of controls (Step 3). Audit procedures Sample size Items to select Timing

22. Methodology for Designing Tests ofBalances – Accounts Receivable Identify client business risks affecting accounts receivable. Set tolerable misstatement and assess inherent risk for accounts receivable. Assess control risk for sales and collection cycle.

23. Methodology for Designing Tests ofBalances – Accounts Receivable Design and perform tests of controls and substantive tests of transactions for sales and collection cycle. Design and perform analytical procedures for accounts receivable balance.

24. Methodology for Designing Tests ofBalances – Accounts Receivable Design tests of details of accounts receivable balance to satisfy balance-related audit objectives. Audit procedures Sample size Items to select Timing

25. Approach to Designing Tests of Details of Balances Apply transaction- related audit objectives to a class of transactions. Identify key controls and make a preliminary assessment of control risk. Design substantive tests of transactions. Design tests of controls. Audit procedures Sample size Items to select Timing

26. Approach to Designing Tests of Details of Balances Design tests of controls. Apply balance-related audit objectives to an account balance. Design substantive tests of transactions. Design tests of details of balances. Audit procedures Sample size Items to select Timing

27. Approach to Designing Tests of Details of Balances Apply balance- related audit objectives to an account balance. Decide tolerable misstatement. Make preliminary judgment about materiality. Design analytical procedures. Assess inherent risk. Decide acceptable audit risk. Design tests of details of balances. Assess client business risk.

28. Learning Objective 6 Compare and contrast transaction-related audit objectives and balance- related audit objectives.

29. Relationship of Transaction- toBalance-Related Audit Objectives Transaction-Related Balance-Related Nature of Audit Objective Audit Objective Relationship Existence Existence or Direct completeness Completeness Completeness or Direct existence Accuracy Accuracy Direct

30. Relationship of Transaction- toBalance-Related Audit Objectives Transaction-Related Balance-Related Nature of Audit Objective Audit Objective Relationship Classification Classification Direct Timing Cutoff Direct Posting and Detail tie-in Direct summarization

31. Relationship of Transaction- toBalance-Related Audit Objectives Transaction-Related Balance-Related Nature of Audit Objective Audit Objective Relationship Realizable value None Rights and None obligations Presentation and None disclosure

32. Learning Objective 7 Integrate the four phases of the audit process.

33. Summary of theAudit Process Phase I Plan and design an audit approach. Phase III Perform analytical procedures and tests of details of balances. Phase II Perform tests of controls and substantive tests of transactions. Phase IV Complete the audit and issue an audit report.

34. Summary of the Audit ProcessPhase I Accept client and perform initial planning. Understand the client’s business and industry. Assess client’s business risk. Perform preliminary analytical procedures. Set materiality and assess acceptable audit risk and inherent risk. Understand internal control and assess control risk. Develop overall audit plan and audit program.

35. Summary of the Audit ProcessPhase II Plan to reduce assessed level of control risk? No Yes Perform tests of controls. Perform substantive tests of transactions. Assess likelihood of misstatements in financial statements.

36. Summary of the Audit ProcessPhase III Low Medium High or unknown Perform analytical procedures. Perform tests of key items. Perform additional tests of details of balances.

37. Summary of the Audit ProcessPhase IV Review for contingent liabilities. Review for subsequent events. Accumulate final evidence. Evaluate results. Issue audit report. Communicate with audit committee and management.
