You are an audit senior on the Shady Oaks engagement. Your initial review of the business has highlighted the following significant risks.

• 1. Payroll expenseShady Oaks employs, in addition to its full-time staff, a significant number of casual nursing, cleaning, and administrative staff. Overtime is often worked on weekends and night shifts due to a shortage of staff. Payment at overtime rates for standard weekend and night shifts has been a common occurrence.
• 2. Accounts payableShady Oaks also has a large number of suppliers for various medical supplies and drugs. Paying the supplier twice for the same purchase has been a continuing problem.

• 2. The details on the supplier's invoice are matched to the appropriate receiving report.
• 3. The details on the supplier's invoice and receiving report are matched to an authorized purchase order.
• 4. The cheque requisition is stapled to the authorized purchase order, receiving report, and supplier's invoice and forwarded to the appropriate senior staff member for review and authorization.
• 5. The authorized cheque requisition, together with the supporting documents, is passed to accounts payable for payment.

Required:

• a Identify the key assertion at risk for payables in relation to payments made prior to receipt of goods.
• b For the control procedures (1) to (5) above for payables:
• i. Identify the key preventive internal control that directly addresses the risk of payments being made by Shady Oaks to its suppliers before the goods are received.
