Final answer:
An audit approach for Balley Books should include identifying missing controls, conducting tests of transactions against market norms, reviewing contracts, and examining the inventory valuation process. The discovery is aimed at identifying overpayments and kickback schemes.
Step-by-step explanation:
Control Explanation
Desirable controls in a purchasing system would include segregation of duties, periodic reviews by an independent party, competitive bidding policies, and a limit on purchase authorization. In the scenario described, missing controls include audit or review of purchasing agents' performance and validation of pricing from vendors. Deviations that could occur include overcharging, kickbacks, and failure to follow competitive bidding procedures.
Tests of Controls
Procedures might involve analyzing purchasing patterns for unusual activity, comparing prices paid to average market prices, interviewing employees, and reviewing authorization trails for transactions. In the absence of formal controls, the focus should be on reviewing detailed transaction records and potential patterns indicating kickbacks, deviations from normative practices.
Audit of Balance
To verify the existence and valuation of inventory, auditors could conduct physical inventory counts and reconcile them to records. To ensure the completeness of inventory and cost of goods sold, auditors could trace transactions from purchase orders to payment and into the financial records. For rights and obligations, it's important to examine contracts and agreements with vendors.
Discovery Summary
The discovery process is expected to reveal whether there have been overpayments to vendors and if the feared kickback scheme exists, ultimately affecting the accuracy of Balley Books' financial statements.
