Concept of Audit Working Paper

Audit working papers (AWPs) are the primary records created by auditors during an audit engagement. They serve as a comprehensive documentation of the audit process, including:

• Audit procedures applied (e.g., tests of controls, substantive procedures).
• Evidence obtained (e.g., bank statements, invoices, management representations).
• Conclusions reached (e.g., assessment of internal controls, detection of misstatements).

Working papers are not the client’s records but are prepared by the auditor for internal use. They are governed by International Standards on Auditing (ISA 230), which mandates their proper preparation, retention, and confidentiality.

Features of a Good Audit Working Paper

A well-prepared audit working paper must possess the following essential features to ensure effectiveness, professionalism, and compliance with auditing standards:

1. Accuracy

• Must be free from errors, omissions, or misstatements.
• All figures, calculations, and conclusions must be verified and cross-checked.
• Example: If an auditor notes a discrepancy in a bank reconciliation, the working paper must correctly reflect the corrected balance.

2. Completeness

• Should fully document all audit procedures performed, including:
  • Planning documents (e.g., audit programs, risk assessments).
  • Evidence gathered (e.g., samples tested, confirmations received).
  • Findings and conclusions (e.g., material weaknesses, adjustments proposed).
• Example: If the auditor tests 50 sample invoices, the working paper must record the sample size, selection method, and results.

3. Clarity

• Must be easy to understand for another auditor reviewing the papers.
• Use clear headings, bullet points, and concise language.
• Avoid ambiguity in explanations (e.g., instead of "Check for errors," write "Vouch 100 sales invoices to supporting documents").
• Example:
  • ❌ "Review AR aging." ✅ "Test 100 accounts receivable aging as of 31/12/2080; confirm no balances >90 days are uncollected."

4. Conciseness

• Should avoid unnecessary details while ensuring key information is retained.
• Use tables, schedules, and checklists for repetitive data.
• Example:
  • Instead of listing all 200 inventory items, summarize in a schedule with totals.

5. Objectivity

• Must be unbiased and professional, reflecting the auditor’s independent judgment.
• Avoid personal opinions or subjective comments (e.g., "Management seems dishonest").
• Example:
  • ❌ "The CFO’s explanation is suspicious." ✅ "CFO’s explanation regarding missing inventory lacks supporting documentation; investigate further."

6. Timeliness

• Should be prepared promptly during the audit to ensure relevance.
• Delays may lead to outdated evidence or incomplete documentation.
• Example: If an auditor identifies a fraud risk on 15 Chaitra 2081, the working paper must be updated immediately with follow-up actions.

7. Proper Identification

• Must be clearly labeled with:
  • Date of preparation.
  • Name of preparer and reviewer.
  • Reference to related working papers (e.g., "See AR Schedule-01").
  • Client and audit engagement details.
• Example:

  Audit Working Paper
  Client: XYZ Ltd. | Audit Date: 2081/03/15
  Preparer: Ram Prasad | Reviewer: Sita Devi
  Reference: Cash Verification-03 | Related: Bank Reconciliation-02
  

8. Cross-Referencing

• Should link to other working papers and source documents for traceability.
• Example:
  • If an auditor traces a sales transaction to an invoice, the working paper should note: "See Invoice No. 5001 (Attached) → Posted to GL Account 400 (Sales Ledger-05)."

9. Permanence (Retention)

• Must be retained as per legal and professional requirements (typically 5–7 years in Nepal).
• Stored securely to prevent loss or tampering.
• Example: Under Company Act 2063, audit papers must be kept for at least 5 years post-audit.

10. Confidentiality

• Must be protected from unauthorized access (e.g., stored in locked cabinets, encrypted digitally).
• Shared only with authorized parties (e.g., audit partners, regulators like SEBON).
• Example: If an auditor leaves the firm, working papers must be returned or securely archived.

Practical Example of a Good Audit Working Paper

Consider an audit procedure to verify cash balances in a bank account:

**Audit Working Paper**
**Client:** ABC Enterprises | **Audit Date:** 2081/03/20
**Preparer:** Hari KC | **Reviewer:** Bina Shrestha
**Reference:** Cash Verification-04 | **Related:** Bank Reconciliation-03

**Objective:**
Verify the accuracy of cash balance per bank statement as of 31/12/2080.

**Procedure Performed:**
1. Obtained **Bank Statement (Jan 2081)** from client.
2. Compared **Bank Statement Balance (Rs. 4,500,000)** with **General Ledger (Rs. 4,200,000)**.
3. Identified **discrepancy of Rs. 300,000** (unrecorded deposit).
4. Vouched **unrecorded deposit** to **Bank Advice Slip (No. 1005, dated 28/12/2080)**.
5. Confirmed **no outstanding checks >90 days** (all cleared within 30 days).

**Findings:**
- **Material discrepancy detected:** Rs. 300,000 unrecorded deposit.
- **Recommendation:** Adjust **Cash GL** by Rs. 300,000 (Credit) and **Bank Reconciliation** to reflect cleared items.

**Supporting Documents:**
- Bank Statement (Attached)
- Bank Advice Slip No. 1005 (Attached)
- General Ledger Extract (See GL-02)

**Conclusion:**
Cash balance is **fairly stated** after adjustment. No further action required.

2. Quality Assurance: Helps supervisors and reviewers assess work efficiently.
3. Efficiency: Well-organized papers reduce rework and save time in future audits.
4. Professional Reputation: Demonstrates due care and compliance with ISA standards.

ISA 230 Compliance Checklist for AWPs

To ensure working papers meet ISA 230 (Audit Documentation), auditors must:

1. Document the basis for conclusions (e.g., "Sample size of 50 items selected using systematic sampling").
2. Retain papers for at least 5 years (or as per local laws).
3. Ensure working papers are sufficient to support the audit report.
4. Include a final review by a senior auditor before submission.
5. Protect confidentiality (e.g., password-protected digital files, locked physical storage).
