1 Overall Audit Plan and Audit Program A424: Chapter 13 I. Introduction Chapter is primarily review and integration of the audit framework. II. Types of Tests used to determine fair presentation of financial statements. A. Procedures to assess risk Procedures to understand entity and environment (see Chapter 8) Procedures to obtain an understanding of internal controls see chapter 10, procedures used to gather information on the design, policies, and procedures of the internal control system. B. Tests of controls (TC) see chapter 10, procedures testing the effectiveness of internal controls. C. Substantive tests of transactions (ST of T) procedures testing the monetary values of transactions for satisfaction of the TRAOs. D. Analytical procedures (AP) use of comparisons and relationships to determine whether account balances or other data appear reasonable. E. Tests of details of balances (TD of B) procedures testing the monetary values of ending balances for satisfaction of the BRAOs. F. Preparation Questions (Use Figure 13-7 as a reference see page 7 of outline): 1. What is the difference between a test of control and a substantive test of transactions? 2. What is the difference between a substantive test of transactions and a test of details of balances? 3. As a matter of convenience and efficiency auditors simultaneously perform some tests of controls and substantive tests of transactions. How is this possible when the extent of the STofT is dependent on the outcomes of the TC? 4. What is the relationship between tests of controls and substantive tests in relation to high assurance? 5. What are the relationships among tests of controls, substantive tests of transactions, analytical procedures, and tests of details of balances? III. Evidence Mix - See table on next page. IV. Design of the Audit Program - See tables on pages 3 and 4. 1

3 Developing an Audit Program A General Framework for Evidence and Procedures: Goal: To gather sufficient competent evidential matter to provide a high level of assurance on the financial statements. Key: For each cycle satisfy all the audit objectives. For each cycle being examined think about the: 1. Documents involved, information they provide, and their flow through the information system. 2. Accounts involved in the cycle and the transfer of information into and out-of the account. Need to meet audit objectives Types of Tests Typical Types of Evidence Procedures to obtain understanding of internal controls Documentation, observation, inquiries, reperformance TRAO Tests of controls Documentation, observation, inquiries, reperformance Substantive tests of transactions Documentation, inquiries, reperformance BRAO Analytical procedures Analytical procedures and inquiries Tests of the Details of Balances Physical examination, confirmation, documentation, inquiries, reperformance and recalculation PDAO Tests for Presentation and Disclosure Auditor decisions on evidence accumulation: 1. Audit procedures to meet audit objectives 2. Sample size 3. Items to select 4. Timing 3
