## Audit Procedures for Opening Balances (SA 510)

In an initial engagement, the incoming auditor has not audited prior period financial statements. Opening balances must be verified because they directly affect current-period figures.

---

### For Inventory (Current Assets)

Three specific procedures are required:

1. Observe the current physical inventory count and reconcile it backward to the opening inventory quantities.

2. Perform valuation procedures on opening inventory items (e.g., cost vs. NRV test).

3. Perform gross profit and cut-off procedures — these indirectly confirm opening inventory correctness through analytical relationships.

---

### For Non-Current Assets and Liabilities

(e.g., Property, Plant & Equipment; Investments; Long-term Debt)

Method	When Used
Examine accounting records and underlying information	Primary approach for most NCA/NCL
Third-party confirmation	For long-term debt (bank confirmation) and investments
Additional audit procedures	Where the above are insufficient

> Key principle: The extent of procedures depends on the assessed risk of material misstatement in the opening balances and the nature of the asset/liability.

Worked example

### Example 1

A company switches auditors in FY 2024-25. The new auditor must verify opening inventory of ₹50 lakhs. Steps: (1) Observe the year-end physical count and reconcile backward using bin cards and stock ledgers to the opening balance. (2) Test valuation — compare cost to NRV for slow-moving items. (3) Compute GP ratio: prior year 32%, current year 31% — consistent, no unexplained fluctuation. All three procedures together provide SAAE for opening inventory.

### Example 2

Opening balance includes long-term bank loan of ₹2 crore. The auditor sends a bank confirmation letter; the lender confirms the outstanding principal and terms as at the start of the current period. This third-party confirmation provides SAAE for the opening NCL balance.

### Example 3

For PPE with opening WDV of ₹1.2 crore, the auditor traces the balance to the prior-year fixed asset register, verifies depreciation rates applied, and inspects ownership documents. Since records are complete, no additional procedures are needed.

⚠️ Common exam mistakes

Assuming the predecessor auditor's work automatically satisfies the incoming auditor's SAAE requirements — the new auditor is independently responsible for opening balances
Using only one procedure for inventory (e.g., examining records) without performing a physical count observation and reconciliation
Confusing verification of the current-period closing count with opening balance verification — the physical count must be traced and reconciled backward to opening figures
Neglecting cut-off procedures when verifying opening inventory — improper cut-off at period end directly distorts opening balances of the next period
