## Physical Inventory Count — Auditor's Attendance under SA 501
### Why the Auditor Attends
Inventories are often material to financial statements. The auditor must obtain sufficient appropriate evidence about their existence and condition. Attending the physical count is the primary procedure.

### Planning the Attendance — Key Matters to Consider
SA 501 requires the auditor to consider the following when planning attendance:
#### Group A — Commonly Listed Matters
| Matter | Why It Matters |
|---|---|
| Nature of inventories | Determines complexity of count procedures (e.g., WIP harder to count than finished goods) |
| Materiality at different locations | Auditor allocates effort to higher-materiality locations |
| Stage of completion of WIP | Partially complete goods are hard to value without knowing stage |
| Perpetual inventory system | May allow count at a date other than year-end |
| Inventories with third parties (service providers) | Must plan separate procedures for these |
| Timing of count (year-end) | Affects cut-off procedures |
#### Group B — Frequently Missed Matters (High-Exam-Value)
> These two are the ones often omitted by students:
1. Whether adequate procedures are expected to be established and proper instructions issued for physical inventory counting.
- The auditor must evaluate management's instructions for recording and controlling the count.
- Knowing how the count will be conducted beforehand allows the auditor to assess its effectiveness before participating.
2. The nature of internal controls related to inventories at different locations.
- Controls at one location may be unsatisfactory, creating a higher risk of material misstatement for that location.
- This affects how much audit work the auditor plans at each location.

### Inventories Held by Third Parties
When inventories are held by external service providers or custodians:
- The auditor should request confirmation of quantities and condition from the third party.
- Or perform inspection or other audit procedures as appropriate.

### Special Consideration: Multiple Locations
When inventories are at multiple locations, the auditor must:
- Assess materiality at each location independently.
- Consider internal control quality at each location — do not assume uniform risk.
- Decide whether to attend all locations or only material ones, based on risk.
