## SA 505: External Confirmation
### Definition
External Confirmation is audit evidence obtained as a direct written response from a third party (the Confirming Party) — in paper form or by electronic medium.
> Key point: The third party responds directly to the auditor, not through the client.
Setup example:
X Ltd (client) → Raju (Debtor) → Balance as on 31.3.2025
Auditor sends request to Raju → Raju replies directly to Auditor.

### Types of External Confirmation
| Type | Mechanism | Evidence Quality |
|---|---|---|
| Positive Confirmation Request | Confirming party responds directly — whether they agree or disagree with the information requested | More persuasive |
| Negative Confirmation Request | Confirming party responds only if they disagree | Less persuasive |
---
### Common Examples of External Confirmations
- Bank confirmation of closing balance
- Debtor confirming outstanding balance or related information
- Stock lying with a third party (e.g., warehouse)
- Assets held as security / collateral with a third party
---
### Audit Procedures — Auditor Must Maintain Control Over the Process
(a) Determine the information to be confirmed — key items such as account balances, agreement terms, side agreements, or absence of certain conditions
(b) Select the appropriate confirming party
(c) Design the confirmation request — responses must come directly to the auditor
(d) Send follow-up requests when no response is received
(e) Evaluate audit evidence — assess reliability/relevance or decide on further procedures
---
### Factors to Consider When Designing Confirmation Requests
| # | Factor |
|---|---|
| a | Assertions being addressed (e.g., Existence, Accuracy — higher risk = stronger need for confirmation) |
| b | Specific identified ROMM, including fraud risks |
| c | Layout and presentation of the confirmation request |
| d | Prior experience from this or similar engagements |
| e | Method of communication (paper or electronic/email) |
| f | Ability of the intended confirming party to confirm the information |
| g | Management authorisation or encouragement to the third party to respond |
---
### Evaluating Audit Evidence — Category of Results
| Result | Implication |
|---|---|
| Agreement / Information without exception | Reliable, relevant AE obtained ✓ |
| Unreliable Response | Response appears fabricated or intercepted — treat as unreliable |
| Non-Response | No reply — perform further audit procedures |
| Response with exception | Discrepancy identified — investigate further |
---
### Management Refusal to Allow Confirmation: Steps for the Auditor
(a) Inquire into management's reasons for refusal
- Obtain AE about the validity and reasonableness of the refusal
(b) Evaluate implications of the refusal on:
- Auditor's assessment of ROMM (including fraud risk)
- Nature, timing, and extent of Further Audit Procedures (FAP)
(c) Perform Alternative Audit Procedures (AAP) to obtain reliable, relevant AE
Critical note: If the auditor concludes that:
- Management refusal is unreasonable, OR
- Reliable, relevant AE cannot be obtained from AAP
→ Communicate to TCWG (per SA 260)
→ Determine impact on auditor's opinion
Examples of AAP:
1. Accounts Receivable — examine subsequent cash receipts, shipping documentation, sales near period-end
2. Accounts Payable — examine subsequent cash payments, Goods Received Notes (GRN)
---
### Negative Confirmation Requests — When Permitted
Negative confirmations provide less persuasive evidence. They may be used only if ALL 4 conditions are satisfied:
1. Assessed ROMM is low AND controls are effective
2. Population consists of numerous, small, homogeneous items
3. A very low exception rate is expected
4. No condition is present that would cause recipients to ignore the request
> Lack of response to a negative confirmation does NOT confirm receipt or accuracy — this is precisely what makes it less reliable.

### Positive Confirmation Requests — Risk & Mitigation
Risk: Confirming party may respond without actually verifying the information.
Mitigation: Use a Blank Confirmation Request — the third party fills in the details themselves (rather than confirming pre-filled figures).
- Reduces the risk of rubber-stamp confirmations
- Trade-off: lower response rate and extra time involved
