a. Mason selected three purchase orders for the purchase of raw materials from LIZ Corporation’s files. He started at the beginning in the accounting process and traced each one through the accounting system. He saw the receiving reports, purchasing agent’s approvals, receiving clerks’ approvals, vendors’ invoices (now stamped paid), entry in the cash disbursement records, and canceled checks. This work gave him a first- hand familiarity with the cash disbursement system, and he felt confident about understanding related questions in the internal control questionnaire completed later.
b. Jarr observed the physical inventory at SER Corporation. She had a list of the different inventory descriptions with the quantities taken from the perpetual inventory records. She selected the 200 items with the largest quantities and counted them after the client’s shop foreperson had completed his count. She decided not to verify the count accuracy of the other 800 items. The shop foreperson miscounted in 16 cases. Jarr concluded the rate of miscount was 8 percent and that as many as 80 of the 1,000 items might be counted incorrectly. As a result, she asked him to recount everything.
