## Reporting Under SA 510 — Modified Opinions for Opening Balance Issues

When the auditor encounters problems with opening balances, the audit report is modified. There are three distinct cases:

---

### Case 1 — Material Misstatement in Opening Balances

Trigger: Opening balances contain a misstatement that materially affects the current period's FS, AND the effect is not properly accounted for, presented, or disclosed.

Opinion: Qualified Opinion or Adverse Opinion

---

### Case 2 — Inconsistent Application of Accounting Policies

Trigger: Either:

Current period accounting policies are not consistently applied relative to opening balances; OR
A change in accounting policy is not properly accounted for or disclosed in accordance with AFRF

Opinion: Qualified Opinion or Adverse Opinion

---

### Case 3 — Unable to Obtain SAAE About Opening Balances

Trigger: The auditor cannot obtain Sufficient Appropriate Audit Evidence regarding opening balances (e.g., records unavailable, predecessor auditor refuses co-operation).

Opinion: Qualified Opinion or Disclaimer of Opinion

---

### Summary Table

Case	Situation	Opinion
1	Material misstatement in OB, not corrected	Qualified / Adverse
2	Inconsistent accounting policies, not disclosed	Qualified / Adverse
3	Unable to obtain SAAE	Qualified / Disclaimer

> Memory rule: Cases 1 & 2 → auditor knows there is a problem → Qualified/Adverse. Case 3 → auditor cannot determine if there is a problem → Qualified/Disclaimer.

Worked example

### Example 1

Predecessor auditor's records are unavailable; management cannot provide supporting documents for opening inventory of ₹80 lakhs (material amount). The auditor cannot obtain SAAE → Issues a Disclaimer of Opinion (Case 3).

### Example 2

Audit of FY 2024-25 reveals opening retained earnings were overstated by ₹40 lakhs due to a prior year revenue overstatement that materially affects current year comparatives. Management refuses to restate. Auditor issues Qualified Opinion (Case 1).

### Example 3

Company changed depreciation method from WDV to SLM in the current year but did not disclose this policy change in the notes to accounts. Opening balances reflected WDV; current year uses SLM without disclosure. Auditor issues Qualified Opinion (Case 2).

⚠️ Common exam mistakes

Confusing Case 3 (cannot obtain evidence) with Case 1 (evidence shows misstatement) — Case 3 leads to Disclaimer, not necessarily Adverse Opinion
Thinking any accounting policy change triggers a modified opinion — it only does so if the change is not properly accounted for or not adequately disclosed
Assuming the predecessor auditor's clean opinion protects the incoming auditor — each auditor is independently responsible for the period they report on
Mixing up Adverse and Disclaimer: Adverse = auditor knows FS are materially misstated; Disclaimer = auditor cannot form an opinion due to lack of evidence
