Auditing Inventory: Observation Procedures for the CPA Exam
Master inventory observation procedures for the CPA AUD exam. Covers physical count attendance, test counts, cycle counting, and inventory held by third parties.
The Auditor's Responsibility for Inventory Observation
Inventory observation is a critical audit procedure because inventory is often a significant asset on the balance sheet and is susceptible to theft, obsolescence, and valuation errors. Under AU-C Section 501, when inventory is material to the financial statements, the auditor must obtain sufficient appropriate audit evidence regarding the existence and condition of inventory by attending the physical inventory counting, unless impracticable. This attendance has been a fundamental audit procedure since the early development of auditing standards.
The auditor's attendance at the physical inventory count serves multiple purposes. It allows the auditor to evaluate management's instructions and procedures for recording and controlling the count, observe the performance of management's count procedures, inspect the inventory, and perform test counts. The auditor's role is not to count all inventory but to evaluate whether management's counting procedures are adequate and are being followed.
Planning Inventory Observation
Understanding the Client's Count Procedures
Before attending the count, the auditor reviews the entity's written count instructions, understands the inventory system (perpetual or periodic), identifies locations where inventory is stored, determines the timing and nature of the count, and evaluates the count procedures for completeness and accuracy. The auditor should understand how the entity handles count tags or sheets, how cutoff is established, and how discrepancies are investigated and resolved.
Determining the Extent of Observation
The extent of the auditor's observation depends on the assessed risk of material misstatement for inventory assertions, the nature and volume of inventory, and the number and locations of inventory storage facilities. For entities with inventory at multiple locations, the auditor may need to attend counts at several sites based on a risk assessment of each location's materiality and susceptibility to misstatement.
Procedures During the Count
Observing Count Procedures
During the count, the auditor observes whether count teams are following the established instructions, whether the counting area is organized to prevent double-counting or omission, whether movement of inventory is controlled during the count, and whether damaged or obsolete items are identified and segregated. The auditor notes the last shipping and receiving documents to establish proper cutoff.
Performing Test Counts
The auditor performs test counts by independently counting selected items and comparing the results to the entity's count records. Test counts typically include tracing from the physical inventory to the count records (to test completeness) and from the count records to the physical inventory (to test existence). The auditor documents the items tested and the results, including any discrepancies.
Evaluating Cutoff
Proper cutoff ensures that all inventory transactions are recorded in the correct period. The auditor records the last receiving report number and the last shipping document number used before the count and subsequently traces these to the accounting records to verify that sales and purchases are recorded in the proper period.
Special Considerations
Cycle Counting
Some entities use cycle counting instead of a full annual physical count, counting portions of inventory on a rotating basis throughout the year. When the entity uses cycle counting, the auditor evaluates whether the cycle counting procedures and perpetual inventory records are adequate substitutes for a full physical count. The auditor may attend one or more cycle counts and test the perpetual records.
Inventory Held by Third Parties
When inventory is held by third parties such as public warehouses or consignees, the auditor must obtain sufficient evidence about the existence and condition of that inventory. Procedures may include confirming the inventory with the third party, inspecting the inventory at the third-party location, obtaining a report on the third party's controls (such as a SOC 1 report), or examining documentation supporting the inventory held.
When Attendance Is Impracticable
If attendance at the physical count is impracticable due to factors such as the nature and location of inventory, the auditor should perform alternative procedures such as observing a count at an alternative date and testing intervening transactions. If the auditor cannot attend and cannot perform adequate alternative procedures, the auditor must modify the audit opinion.
CPA Exam Preparation Points
- The auditor attends and observes the client's count; the auditor does not conduct the count.
- Test counts should trace both directions: from floor to records and from records to floor.
- Cutoff procedures require documenting the last shipping and receiving documents used before the count.
- For inventory held by third parties, confirmation alone may not be sufficient if the amounts are material.
- If the auditor is appointed after year-end and cannot observe the count, alternative procedures or an opinion modification may be necessary.
