Problem 10 -21, page 317 The following are audit procedures from different transaction cycles

Problem 10 -21, page 317 The following are audit procedures from different transaction cycles 1. Examine sales invoices for evidence of internal verification of prices, quantities, and extensions. 2. Select items from the client’s perpetual inventory records and examine the items in the company’s warehouse. 3. Use audit software to foot and cross-foot the cash disbursements journal, and trace the balance to the general ledger. 4. Select a sample of entries in the acquisitions journal, and trace each one to a related vendors’ invoice to determine whether one exists. 5. Examine documentation for acquisition transactions before and after the balance sheet date to determine whether they are recorded in the proper period. 6. Inquire of the credit manager whether each account receivable on the aged trial balance is collectible. 7. Compute inventory turnover for each major product, and compare with that of previous years. 8. Confirm a sample of notes payable balances, interest rates, and collateral with lenders. 9. Use audit software to foot the accounts payable trial balance, and compare the balance with the general ledger. Required: a. For each audit procedure, identify the transaction cycle being audited. b. For each audit procedure , identify the type of evidence. c. For each audit procedure, identify whether it is a test of control or substantive test. d. For each substantive audit procedure, identify whether it is a test of transactions, a test of details of balances or an analytical procedure. e. For each test of control or substantive test of transactions procedure, identify the transaction-related audit objective or objectives being satisfied. f. For each analytical procedure or test of details of balances procedure, identify the balance-related audit objective or objectives being satisfied. Audit Strategy 25

Problem 10 -23, page 318 Kim Bryan, a new staff auditor, is confused by

Problem 10 -23, page 318 Kim Bryan, a new staff auditor, is confused by the inconsistency of the three audit partners to whom she has been assigned on her first three audit engagements. On the first engagement, she spent a considerable amount of time in the audit of cash disbursements by examining cancelled cheques and supporting documentation, but almost no time was spent on the verification of capital assets. On the second engagement, a different partner had her do less intensive tests in the cash disbursements area and take smaller sample sizes than in the first audit even though the company was much larger. On her most recent engagement under a third audit partner, there was a thorough test of cash disbursement transactions, far beyond that of the other two audits, and an extensive verification of capital assets. In fact, this partner insisted on a complete physical examination of all capital assets recorded on the books. The total audit time on the most recent audit was longer than that of either of the first two audits in spite of the smaller size of the company. Bryan’s conclusion is that the amount of evidence to accumulate depends on the audit partner in charge of the engagement. Required: a) State the differences in risk assessments that could affect the amount of evidence accumulated in each of the three audit engagements as well as the total time spent. b) What could the audit partners have done to help Bryan understand the differences in the audit emphasis on the three audits? c) Explain how these three audits are useful in developing Bryan’s professional judgment. How could the quality of her judgment have been improved by the audits? Audit Strategy 26

Problem 10 -24, page 318 Assume that the client’s internal controls over the recording

Problem 10 -24, page 318 Assume that the client’s internal controls over the recording and classifying of fixed assets additions are considered deficient because the individual responsible for recording new acquisitions has inadequate technical training and limited experience ion accounting. Required: a. What value would you assign to control risk? Why? b. How will this situation affect the evidence you should accumulate in auditing fixed assets as compared with another audit in which controls are excellent? Be as specific as possible. Audit Strategy 27
