## Preparation of Audit Documentation

### The Core Standard: The 'Experienced Auditor' Test

The auditor must prepare AD such that an experienced auditor, having no previous connection with the audit, can understand:

(a) The Nature, Timing, and Extent (NTE) of audit procedures performed.

(b) The Results of those procedures — i.e., the audit evidence obtained.

(c) Significant matters arising during the audit, the significant professional judgements made, and the conclusions reached.

> This is the benchmark: not just your own understanding, but a fresh experienced professional's understanding.

### What to Record When Documenting NTE (Note 1)

When recording Nature, Timing, and Extent of audit procedures performed, the auditor must record:

Requirement	What to Document
(A) Identifying characteristics	Specific items tested (e.g., invoice numbers, sample items)
(B) Who + When	Who performed the audit work + Date work was completed
(C) Who reviewed + When + Extent	Who reviewed the work + Date + Extent of that review

---

### Factors Affecting Form, Content, and Extent of AD

#	Factor	More AD (ADM)	Less AD (ADB)
i	Size & complexity of entity	Large, complex entity	Small, simple entity
ii	Identified Risk of Material Misstatement (ROMM)	High ROMM	Low ROMM
iii	Nature of audit procedure	Significant audit evidence / ADP	Less significant evidence
iv	Significance of audit evidence obtained	Highly significant	Less significant
v	Nature & extent of audit exceptions	Revenue misstatement	Petty cash discrepancy
vi	Methodology & tools	CAAT (Computer-Assisted Audit Techniques) used	Manual procedures
vii	Conclusion not easily determinable	Document basis for conclusion clearly	—

> Rule of thumb: Risk ↑ → Documentation ↑; Significance ↑ → Documentation ↑.

Worked example

### Example 1

Q: An auditor tests a sample of 25 purchase invoices. What identifying characteristics should be documented?

A: The auditor must record the specific invoice numbers (or other unique identifiers) selected for testing, who performed the test (e.g., CA student's name), the date of testing, who reviewed the work, and the date and extent of that review.

### Example 2

Q: Audit is being performed for a large listed company with complex revenue recognition. Should AD be more extensive or less extensive compared to a small proprietary firm?

A: More extensive — two factors demand this: (i) Size and complexity is high (large listed entity), and (ii) Revenue recognition complexity increases ROMM. Both factors push towards ADM (more documentation).

### Example 3

Q: The auditor concludes that a particular accounting estimate is reasonable, but the reasoning is complex. What should the auditor do?

A: Per Factor (vii), when the basis for a conclusion is not easily determinable from the procedures alone, the auditor must explicitly document the reasoning/basis for the conclusion — not just record 'estimate is reasonable.'

⚠️ Common exam mistakes

Stating the 'experienced auditor' test without the key qualifier — it must be an experienced auditor with NO PREVIOUS CONNECTION to the audit (i.e., a fresh reader).
Forgetting that documenting NTE requires THREE elements: identifying characteristics of items tested + who performed + who reviewed (with dates).
Assuming more documentation is always better — AD should be proportionate. Factors can reduce or increase documentation needs.
Confusing 'results of procedures' with 'audit opinion' — results are the raw evidence/findings from each procedure, not the final conclusion.

The auditor shall prepare audit documentation that is sufficient to enable an experienced auditor, having no previous connection with the audit, to understand: (a) The nature, timing, and extent of the audit procedures performed to comply with the SAs and applicable legal and regulatory requirements; (b) The results of the audit procedures performed, and the audit evidence obtained; and (c) Significant matters arising during the audit, the conclusions reached thereon, and significant professional judgments made in reaching those conclusions.
