  1. Overall Audit Planand Audit Program Chapter 10

  2. Learning Objective 1 Use the five types of audit tests to determine whether financial statements are fairly stated.

  3. Types of Tests Procedures to obtain an understanding of internal control Tests of control Substantive tests of transactions Analytical procedures Tests of details of balances

  4. Audit Risk Model = PDR AAR IR × CR Types of Audit Tests Procedures to obtain an understanding of internal control Tests of controls (TOC) Substantive tests of transactions (STOT) + + Types of Audit Tests andthe Audit Risk Model

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 TDP TOC+STOT+AP+TDP = Sufficient competent evidence per GAAS Role of all Audit Tests in the Sales and Collection Cycle

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

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 Audit Assurance at Different Levels of Internal Control Effectiveness

  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. Program change controls Access controls 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.

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

  15. Procedures to Obtain an Understanding of Internal Control Tests of Controls Audit 1 E E Variations in Evidence Mix 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. 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 Four-Step Approach to Designing Control and Substantive Tests Apply transaction- related audit objectives to a class of transactions (Step 1).

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

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

  23. 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

  24. 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 Approach to Designing Tests of Details of Balances Apply transaction- related audit objectives to a class of transactions.

  25. Design tests of details of balances. 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. Audit procedures Sample size Items to select Timing

  26. 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.

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

  28. 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

  29. 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

  30. 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

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

  32. 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. Summary of theAudit Process

  33. 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.

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

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

  36. 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.
