## SA-510: Initial Audit Engagements — Opening Balances

### Key Definitions

Initial Audit Engagement: An engagement where either:

The prior period FS were not audited, OR
The prior period FS were audited by a predecessor auditor

Predecessor Auditor: An auditor from a different audit firm who audited the entity in the prior period and has been replaced by the current auditor.

---

### Objective

Obtain S&A evidence that:

1. Opening balances do not contain misstatements that materially affect current period FS

2. Appropriate accounting policies have been consistently applied in the current period FS

---

### Audit Procedures for Opening Balances

Auditor determines whether:

1. Prior period closing balances are properly brought forward (or adjustments disclosed)

2. Opening balances reflect appropriate accounting policies

3. Perform one or more of:

Review copies of prior year audited financial statements
Evaluate whether current year audit procedures provide evidence on opening balances
Perform specific audit procedures to obtain evidence on opening balances

If misstatement found: Perform necessary procedures → Communicate with TCWG → Issue Modified Report

If insufficient evidence obtained: Issue Modified Report

---

### Evidence for Current vs. Non-Current Items

Current Assets (e.g., Inventories):

Current period inventory procedures provide little evidence about opening inventory. Additional procedures:

Observe current physical inventory count; reconcile to opening quantities
Audit procedures on valuation of opening inventory items
Audit procedures on gross profit and cut-off

Non-Current Assets/Liabilities (e.g., PPE, investments, long-term debt):

Examine accounting records and information underlying the opening balances
Obtain confirmation from third parties where feasible

---

### Accounting Policies

Auditor must obtain S&A evidence that:

Accounting policies are consistently applied
Any change is disclosed as per FRF

Situation	Report
Consistent policies, no issues	Unmodified
Inconsistent or change not disclosed	Modified

---

### Modification in Prior Year Auditor's Report

1. Check whether the PY report was modified

2. If modified: discuss with management and predecessor auditor; determine whether the material misstatement exists in the current year

Situation	Report
Material misstatement still exists in CY	Modified
Material misstatement does not exist in CY	Unmodified

Worked example

### Example 1

Opening Inventory — Current Asset: A new auditor takes over the audit of a manufacturing company. For the opening inventory balance, the auditor cannot simply rely on current year procedures. Instead, the auditor: (a) observes the current physical count and reconciles back to opening quantities; (b) examines valuation documents (cost sheets, NRV estimates) for opening inventory items; (c) performs gross profit analysis and cut-off procedures to verify the opening position.

### Example 2

Prior Year Modified Report: The predecessor auditor issued a qualified opinion due to a material misstatement in a non-current asset balance. The current auditor discusses this with management and the predecessor. After examining current year records, the auditor determines the misstatement has been corrected and does not exist in the current year. The current auditor may therefore issue an unmodified report, provided no new issues arise.

⚠️ Common exam mistakes

Assuming 'initial audit engagement' only means the entity has never been audited — it also includes situations where a predecessor auditor did the prior year work.
Assuming current year audit procedures are sufficient for opening inventory — additional specific procedures (physical count reconciliation, valuation, gross profit tests) are always required for current assets.
Issuing an unmodified report without checking consistency of accounting policies — even if opening balances are materially correct, an unexplained policy change requires a modified report.
Forgetting to check whether a prior year modification is still relevant in the current year before deciding on report type.
