AU-C § 315: Identifying and Assessing the Risk of Material Misstatement (RMM)
Under AU-C § 315 (AICPA / FASB / IRS), identifying and Assessing the Risk of Material Misstatement (RMM) establishes the authoritative rules tested on the CPA Exam. Develop the core audit skill of identifying and assessing the risk of material misstatement (RMM) by breaking down its components, applying a structured process, and linking risks to specific financial statement assertions.

Worked Example: Assessing RMM at TechGadget Inc.
| Account | Assertion | Inherent Risk (IR) | Control Risk (CR) | Overall RMM Assessment | Rationale |
|---|---|---|---|---|---|
| Inventory | Valuation | High | High | High | Rapid obsolescence (high IR) combined with weak controls to identify it (high CR). |
| Revenue | Occurrence | Low | Low | Low | Standard sales are straightforward (low IR) and controls are strong (low CR). |
| Revenue | Accuracy | High | Low | Moderate | Complex rebate calculations (high IR) are mitigated by strong automated controls (low CR). |
Under AU-C 315, after an auditor has identified risks of material misstatement at the financial statement level and the assertion level, what is the auditor's required next step in the risk assessment process?
Worked Example: Assessing RMM at TechGadget Inc.
Scenario. You are auditing TechGadget Inc., a manufacturer of consumer electronics, for the year ended December 31.
- Step 1: Understand the Entity and Identify Inherent Risks. Your understanding reveals that TechGadget operates in a highly competitive market with rapid technological obsolescence. They offer complex sales arrangements with rebates and return rights. This points to high inherent risk in two key areas: Inventory: High risk of obsolescence due to rapid product cycles. Revenue: High risk of misstatement due to complex terms (variable consideration).
- Step 2: Evaluate Control Risk. You test TechGadget's controls. You find that their quarterly inventory review process to identify obsolete stock is informal and poorly documented. However, their controls over revenue recognition for standard sales are well-designed and operating effectively. You assess control risk for inventory as high, and for standard revenue as low.
- Step 3: Assess RMM at the Assertion Level. Based on the IR and CR assessments, you determine the overall RMM for key assertions:
- | Account | Assertion | Inherent Risk (IR) | Control Risk (CR) | Overall RMM Assessment | Rationale | | :--- | :--- | :--- | :--- | :--- | :--- | | Inventory | Valuation | High | High | High | Rapid obsolescence (high IR) combined with weak controls to identify it (high CR). | | Revenue | Occurrence | Low | Low | Low | Standard sales are straightforward (low IR) and controls are strong (low CR). | | Revenue | Accuracy | High | Low | Moderate | Complex rebate calculations (high IR) are mitigated by strong automated controls (low CR). |
