(a) Definition and Application of Forensic Auditing
Forensic auditing is a specialized field of auditing that involves the use of accounting, auditing, and investigative techniques to examine financial records for evidence of fraud, misappropriation, or other financial irregularities, often for legal proceedings.
Application to Fraud Investigations:

1. Evidence Gathering: Forensic auditing identifies and collects evidence to support or refute allegations of fraud, such as theft of materials or inventory manipulation.
2. Fraud Detection: It employs analytical procedures and data analysis to detect anomalies, such as unusually high material consumption or inventory discrepancies.
3. Legal Support: Findings are documented to withstand legal scrutiny, often used in court or by management to pursue disciplinary or legal action.
4. Root Cause Analysis: It investigates the underlying causes of fraud, such as weak internal controls, to recommend preventive measures.
5. Stakeholder Assurance: Provides assurance to management or regulators that financial irregularities are thoroughly investigated.

(b) Matters and Procedures for Planning the Investigation
Matters to Consider:

1. Scope of Losses: High material consumption (74.1% vs. 70% historical) and low gross profit (7.2% vs. 18.6%) suggest potential fraud or errors in the quarter to 30 June 20X8.
2. Control Weaknesses: Lack of perpetual inventory records and manual valuation increase the risk of errors or manipulation.
3. Fraud Risk: Possible theft, wastage, or under-counting of inventory requires investigation of employee access and controls.
4. Customer-Specific Production: Custom manufacturing may lead to misallocation of materials or unrecorded costs.
5. Management Accounts Reliability: The 31 March 20X8 accounts are assumed correct, providing a baseline for comparison.

Procedures:

1. Review Management Accounts: Compare 30 June 20X8 accounts with prior quarters for consistency and anomalies.
2. Interview Management: Discuss suspected causes (theft, wastage, inventory errors) and management’s response to losses.
3. Assess Controls: Evaluate inventory count procedures, material requisition processes, and segregation of duties.
4. Plan Data Analysis: Analyze purchase invoices and inventory records to trace material usage to customer orders.
5. Site Visit: Observe inventory storage and count processes to identify security or procedural weaknesses.
6. Engage Experts: Consider using forensic specialists for data analytics or physical security assessments.
7. Timeline and Resources: Establish a timeline for the investigation and allocate staff with fraud investigation expertise.
8. Document Fraud Indicators: Note red flags like high material costs or discrepancies in inventory sheets.
9. Liaise with Management: Agree on reporting format and scope to meet Dominic Co’s objectives.
10. Review Legal Implications: Assess whether findings may lead to legal action, ensuring evidence is court-admissible.

(c) (i) Matters to Consider for Inventory Undervaluation

1. Counting Errors: Manual counts may miss items or include obsolete stock, leading to under-valuation.
2. Valuation Method: Incorrect application of cost (e.g., omitting labour or overheads) or use of outdated prices.
3. Cut-off Issues: Goods received or issued near 30 June 20X8 may be omitted or double-counted.
4. Theft or Loss: Unrecorded theft or damage could reduce reported inventory.
5. Comparison with Prior Quarters: Closing inventory of C162,000 (30 June) is lower than C180,000 (31 March), despite higher material purchases (C318,000 vs. C235,000).

(ii) Tests to Quantify Undervaluation

1. Reperform Count: Conduct an independent count of inventory at 30 September 20X8, reconciling to 30 June records.
2. Vouch Inventory Sheets: Trace items on 30 June count sheets to purchase invoices and goods received notes.
3. Test Valuation: Recalculate inventory value using cost records, ensuring inclusion of material and labour costs.
4. Cut-off Testing: Review goods received and issued notes around 30 June 20X8 to ensure proper inclusion.
5. Analytical Review: Compare inventory turnover and material consumption ratios with prior quarters to identify anomalies.
6. Inspect Storage: Check for unrecorded or damaged stock that may have been excluded from counts.

(d) (i) Reasons for High Materials Consumption

1. Inventory Undervaluation: Under-counting or under-valuing closing inventory inflates cost of sales, increasing material consumption.
2. Excessive Wastage: Poor production processes or defective materials may lead to higher usage.
3. Theft: Employees or external parties may be stealing materials, not recorded as issued.
4. Misallocation: Materials for one customer order may be incorrectly charged to another, inflating costs.
5. Recording Errors: Manual systems may lead to duplicate or erroneous material purchase entries.

(ii) Tests to Determine Correctness of Materials Consumption

1. Trace Purchases: Match material purchase invoices to goods received notes and customer orders.
2. Analyze Usage: Compare material requisitions to production output to assess wastage or over-consumption.
3. Security Review: Inspect storage areas and access logs to identify potential theft.
4. Reconcile Records: Reconcile material purchases (C318,000) to inventory and cost of sales, checking for errors.
5. Customer Order Analysis: Allocate material costs to specific orders to verify correct charging.
6. Test Controls: Review approval processes for material requisitions to detect unauthorized usage.
7. Interview Staff: Discuss material handling procedures with production and warehouse staff to identify discrepancies.
