Evaluating Uncorrected Misstatements, Communication with TCWG, Written Representations, and Documentation

## SA 450: Handling Uncorrected Misstatements

When management refuses to correct a misstatement, the auditor's work does not stop — it shifts to evaluation, communication, and documentation.

---

### Step 1 — Understand Management's Reasons

Before concluding, the auditor must understand why management refuses to correct the misstatement. This understanding feeds into the next evaluation.

---

### Step 2 — Evaluate Materiality of Uncorrected Misstatements

The auditor determines whether uncorrected misstatements are material, individually or in aggregate.

Two dimensions to assess:

DimensionWhat to consider
Size & NatureRelation to specific classes of transactions, account balances, disclosures, and the FS as a whole; circumstances of occurrence
Prior Period EffectWhether uncorrected misstatements from prior periods affect current-period classes of transactions, balances, disclosures, or FS overall

> Key insight: A misstatement that is small individually can still be material when combined with others (aggregate effect). Never evaluate in isolation.

---

### Step 3 — Communicate with TCWG (SA 260)

  • Communicate all uncorrected misstatements (individually and in aggregate) to Those Charged With Governance (TCWG).
  • Explain the potential effect on the audit opinion.
  • Request that management correct the misstatements.
  • Also communicate the effect of prior-period uncorrected misstatements on current-period account balances, disclosures, and FS.
  • Exception: Communication may be omitted only if prohibited by law or regulation.

---

### Step 4 — Obtain Written Representations (SA 580)

The auditor may request that management and appropriate TCWG confirm in writing (Written Representations) that they believe the effects of uncorrected misstatements are immaterial, individually and in aggregate, to the FS.

  • A summary of uncorrected misstatements must be included in the Written Representation.

---

### Step 5 — Documentation (SA 230)

The audit file must contain:

1. The clearly trivial threshold — the amount below which misstatements are regarded as clearly trivial.

2. All misstatements accumulated during the audit and whether each has been corrected.

3. The auditor's conclusion on whether uncorrected misstatements are material (individually or in aggregate) and the basis for that conclusion.

Worked example

### Example 1

Aggregate Materiality Example:

During an audit, the auditor finds three uncorrected misstatements:

  • Overstatement of revenue: ₹80,000
  • Understatement of expenses: ₹60,000
  • Overstatement of receivables: ₹40,000

Performance materiality is ₹1,50,000. Individually, each is below that threshold. However, the aggregate effect = ₹1,80,000, which exceeds performance materiality. The auditor must treat the combined misstatement as potentially material and communicate it to TCWG.

### Example 2

Prior Period Misstatement Carry-Forward:

In the prior year, a ₹2,00,000 expense was understated and not corrected. In the current year, the auditor must assess whether this prior-period error affects the current year's opening balance of retained earnings and whether the cumulative effect makes the current FS materially misstated. This must be communicated to TCWG along with current-year uncorrected misstatements.

### Example 3

Written Representation Scenario:

Management refuses to reclassify a long-term liability as current (due within 12 months). The misstatement is ₹50 lakhs. Management believes it is immaterial to the FS as a whole (FS total assets = ₹5,000 lakhs). The auditor includes this item in the WR schedule and obtains management's written confirmation that the effect is immaterial. The auditor still evaluates independently whether to agree.

⚠️ Common exam mistakes

  • Evaluating each misstatement only in isolation — forgetting that small individual misstatements can be material in aggregate.
  • Omitting prior-period uncorrected misstatements when assessing the current year's FS.
  • Failing to document the 'clearly trivial' threshold at the start of the audit — this is a required documentation item, not optional.
  • Treating Written Representations as a substitute for audit evidence — they supplement, not replace, the auditor's own evaluation.
  • Omitting the communication to TCWG when management refuses to correct a misstatement, assuming management's refusal is the end of the matter.

The auditor shall determine whether uncorrected misstatements are material, individually or in aggregate. In making this determination, the auditor shall consider: (a) The size and nature of the misstatements, both in relation to particular classes of transactions, account balances or disclosures and the financial statements as a whole, and the particular circumstances of their occurrence; and (b) The effect of uncorrected misstatements related to prior periods on the relevant classes of transactions, account balances or disclosures, and the financial statements as a whole.
