An audit team at Sterling & Co. is in the planning phase for the audit of a new client, Innovatech Solutions, a nonissuer. To comply with AU-C 315, Understanding the Entity and Its Environment and Assessing the Risks of Material Misstatement, which of the following represents the required set of risk assessment procedures the team must perform?

Worked Practitioner Scenario

Worked Example: Risk Assessment for a 'Fast Fashion' Retailer

Scenario: You are the senior auditor for TrendNow Apparel, a retailer specializing in fast fashion. You are planning the audit and assessing the risks of material misstatement.

  1. Step 1: Identify Industry and Key Factors Industry: Retail, specifically the 'fast fashion' niche. Key Factors: Rapidly changing consumer trends, intense price competition, complex global supply chains, and a high volume of product returns.
  2. Step 2: Link Industry Factors to Specific Financial Statement Risks Factor: Rapidly changing trends. Risk: High inherent risk of inventory obsolescence. If a trend dies, the related inventory becomes difficult to sell, potentially at a loss. Account & Assertion at Risk: Inventory and the Valuation and Allocation assertion.
  3. Step 3: Develop a Hypothesis for Analytical Procedures Hypothesis: If TrendNow is managing its inventory effectively, its inventory turnover ratio and gross margin should be comparable to its direct competitors. A significantly lower turnover ratio or declining gross margin could indicate obsolete stock being carried at full cost.
  4. Step 4: Design Specific Audit Procedures Analytical: Calculate inventory turnover and days' sales in inventory. Compare these ratios to prior years and published industry benchmarks. Substantive: During the physical inventory observation, specifically identify and inspect slow-moving or out-of-season items. Inquire with management about their plans for this stock. Test of Details: Test the net realizable value (NRV) of aged inventory by examining recent sales prices of similar items and comparing them to the inventory's carrying cost.
The tempting-but-wrong answer is to immediately jump to vouching a large sample of inventory purchases to invoices. While this test of details is useful for confirming the existence and cost of inventory, it completely fails to address the primary risk in this industry: that the inventory exists and was paid for, but is now worthless because fashion trends have changed. The key is to test valuation, not just existence.
