Parts III, V, and VI of this case study dealt with obtaining an understanding of internal control and assessing control risk for transactions affecting accounts payable of Pinnacle Manufacturing. In Part VII, you will design analytical procedures and design and perform tests of details of balances for accounts payable.

Assume that your understanding of internal controls over acquisitions and cash disbursements and the related tests of controls and substantive tests of transactions support an assessment of a low control risk. The listing of the 519 accounts making up the accounts payable balance of $12,969,686 at December 31, 2011 is included under the Pinnacle link on the textbook Web site.

Required

a. List those relationships, ratios, and trends that you believe will provide useful information about the overall reasonableness of accounts payable. You should consider income statement accounts that affect accounts payable in selecting the analytical procedures.
b. Study Table 19-5 (p. 647) containing balance-related audit objectives and tests of details of balances for accounts payable to be sure you understand each procedure and its purpose. Prepare an audit program for accounts payable in a performance format, using the audit procedures in Table 19-5. The format of the audit program should be similar to Table 16-5 (p. 541). Be sure to include a sample size for each procedure.
c. Assume for requirement b that (1) assessed control risk had been high rather than low for each transaction-related audit objective, (2) inherent risk was high for each balance-related audit objective, and (3) analytical procedures indicated a high potential for misstatement. What would the effect have been on the audit procedures and sample sizes for requirement b?
d. Confirmation requests were sent to a stratified sample of 51 vendors listed in Figure 16-8 (p. 552). Confirmation
