Audit of Inventory – Rights and Existence (SA 501)
## Audit of Inventory: Rights & Existence Assertions
### Rights Assertion
The entity should include only inventory it owns (risks and rewards transferred to entity). Goods held on consignment from third parties must be excluded.
Identify goods held on consignment (NOT owned by entity)
Evaluate consignee goods
Assess whether ownership has actually transferred
Examine invoices — verify client's name
Direct ownership evidence
For inventory held by a third party → Obtain declaration on letterhead, signed by the 3rd party
Third-party confirmation of entity's title
---
### Existence Assertion: Physical Inventory Count (SA 501)
SA 501 requires the auditor to attend physical inventory counting (unless impracticable).
#### Procedures
Evaluate management's counting instructions — are they adequate to produce reliable counts?
During the count:
Participate alongside management (active involvement, not passive watching).
Inspect inventory physically.
Perform test counts — count selected items and compare with count sheets.
Ensure consignee goods are segregated from entity's own inventory.
Perpetual vs. Period-end System:
Inventory System
Count Timing
Perpetual inventory system
Count at interim dates during the year
No perpetual system
Full count at period end (31 March)
Worked example
### Example 1
Test counts: During the physical count the auditor selects 50 line items. For 3 items, count sheets show 200 units but the auditor's independent count yields 180 units. The 20-unit difference per item is investigated — possible counting error, pilferage, or sheet manipulation.
### Example 2
Consignment exclusion: The entity holds goods worth ₹10 lakhs belonging to a client on consignment. The auditor checks: (a) Are these physically segregated? (b) Is there a written consignment agreement? (c) Are they excluded from the entity's balance sheet inventory? If included in the entity's books, this is a rights misstatement requiring an audit adjustment.
### Example 3
Interim count with roll-forward: A company uses a perpetual inventory system. The auditor attends two interim counts (September and January) and performs roll-forward testing to 31 March (checking additions/disposals between count date and year-end) rather than attending a full count on 31 March.
⚠️ Common exam mistakes
Thinking the auditor merely 'observes' the count — SA 501 requires active participation: inspect inventory and perform independent test counts.
Forgetting that consignee goods must be physically segregated AND excluded from the entity's inventory figure.
Not distinguishing the approach for entities with perpetual systems (interim counts) vs. those without (year-end full count).
Ignoring the need for a third-party signed declaration when inventory is held at an external warehouse or by a third party.

Where inventory is material to the financial statements, the auditor shall obtain sufficient appropriate audit evidence regarding the existence and condition of inventory by: (a) attendance at physical inventory counting, unless impracticable, to: (i) evaluate management's instructions and procedures for recording and controlling the results of the entity's physical inventory counting; (ii) observe the performance of management's count procedures; (iii) inspect the inventory; and (iv) perform test counts; and (b) performing audit procedures over the entity's final inventory records to determine whether they accurately reflect actual inventory count results.
