Add the supplier balances in the accounts payable master file, and compare the total with the general ledger.

Discuss the duties of the cash disbursements bookkeeper with him or her, and observe whether he or she has responsibility for handling cash or preparing the bank reconciliation.
Confirm accounts payable balance directly with vendors.
Use generalized audit software to run a gap test on the cheques issued during the year. (Print a list of cheque numbers omitted from the normal cheque number sequencing.)
Examine the treasurer’s initials on monthly bank reconciliations as an indication of whether they have been reviewed.
Examine vendors’ invoices and other documentation in support of recorded transactions in the acquisitions journal.
Multiply the commission rate by total sales, and compare the result with the commission expense.
Examine vendors’ invoices and other supporting documents to determine whether large amounts in the repairs and maintenance account should be capitalized.
Examine the initials on vendors’ invoices that indicate internal verification of pricing, extending, and footing by a clerk.
Required:
Indicate whether each procedure is a test of controls, an analytical procedure, or a test of details of balances.

3. Problem 10-21, page 332
The following are audit procedures from different transaction cycles
Use audit software to foot and cross-foot the cash disbursements journal, and trace the balance to the general ledger.
Select a sample of entries in the acquisitions journal, and trace each one to a related vendors’ invoice to determine whether one exists.
Examine documentation for acquisition transactions before and after the balance sheet date to determine whether they are recorded in the proper period.
Inquire of the credit manager whether each account receivable on the aged trial balance is collectible.
Compute inventory turnover for each major product, and compare with that of previous years.
Confirm with lenders a sample of notes payable balances, interest rates, and collateral.
Use audit software to foot the accounts payable trial balance, and compare the balance with the general ledger.
Required:
For each audit procedure, identify the transaction cycle being audited.
For each audit procedure , identify the type of evidence.
For each audit procedure, identify whether it is a test of control or substantive test (indicating whether it is a test of details of balances or an analytical procedure.)
For each audit procedure, identify the related audit objective(s).
Specifically assess the purpose of each audit procedure, as follows:
For tests of control, state the risk (potential error) that is being assessed.
For analytical procedures, state a possible result that you would expect.
For tests of detail, state the type of material error that you would be quantifying.

6. Problem 12-21, page 406, Canadian 11th. Edition
The following internal controls for the acquisition and payment cycle were selected from a standard internal control questionnaire:
Vendors’ invoices are recalculated prior to payment.
Approved price lists are used for acquisitions.
Prenumbered receiving reports are prepared as support for purchases and are numerically accounted for.
Dates on receiving reports are compared with vendors’ invoices before entry into the accounts payable system.
The accounts payable system is updated, balanced, and reconciled to the general ledger monthly.
Account classifications are reviewed by someone other than the preparer.
All cheques are signed by the owner or the manager.
The cheque signer compares data on the supporting documents with the cheques.
All supporting documents are cancelled after entry.
After they are signed, cheques are mailed by the owner or manager, or a person under his or her supervision.
Required:
For each control, state which transaction-related audit objective(s) is (are) applicable.
For each control, write an audit procedure that could be used to test the control for effectiveness.
For each control, identify a likely misstatement, assuming the control does not exist or is not functioning.
For each likely misstatement, identify a substantive audit procedure to determine if the misstatement exists.
