SA 510 applies when an auditor takes up a company for the first time, either because the previous year was not audited or because a different firm audited it. The new auditor cannot simply start from this year's balances; the standard says what must be checked about the balances brought forward and what happens to the opinion if that cannot be done.

SA 510, as effective for audits of financial statements for periods beginning on or after 1 April 2010, covers every initial engagement. ICAI may revise standards, so check icai.org for the current text. Companies changing auditors can ease the first year with well-kept books of accounts and tied-out opening balances.

Scope and objective (paragraphs 1-4)

"Opening balances" means balances at the start of the period, resting on the prior period's closing balances, past transactions and accounting policies. They also include matters needing disclosure that existed at the start, such as contingencies and commitments (paragraphs 1 and 4(b)). Where comparative figures are presented, SA 710 also applies, and SA 300 covers planning activities before an initial audit begins.

An "initial audit engagement" is one where the prior period was not audited, or was audited by a predecessor auditor, meaning an auditor from a different firm who has been replaced (paragraph 4).

The auditor's objective is to obtain evidence on two points: whether opening balances contain misstatements that materially affect the current period's financial statements, and whether the accounting policies behind them are consistently applied this year, or changes are properly accounted for and disclosed (paragraph 3).

Procedures on opening balances (paragraphs 5-7)

StepWhat the auditor doesParagraph
ReadThe most recent financial statements and the predecessor's report, for information relevant to opening balances and disclosures5
Carry-forwardChecks that prior closing balances were correctly brought forward, or that adjustments are disclosed as prior period items in the current year's Statement of Profit and Loss6(a)
PoliciesChecks that the opening balances reflect appropriate accounting policies6(b)
EvidenceDoes one or more of: perusing the audited prior-year statements and related documents; evaluating whether current-year procedures give evidence on opening balances; performing specific procedures6(c)
Misstatement foundPerforms extra procedures to measure the effect on the current year and communicates to management and those charged with governance under SA 4507

The extent of work depends on the accounting policies, the nature of the balances and the risks, how large the opening balances are compared with the current statements, and whether the prior year was audited and with what opinion (A1).

Where a predecessor audited

The new auditor may be able to get enough evidence by perusing the copies of the audited statements and supporting schedules. Ordinarily the closing balances in the prior statements can be relied on unless current-year work suggests opening misstatements (A2). This part of the Indian text differs from the international standard: the international text lets the new auditor review the predecessor's working papers, but because of the confidentiality obligations in the Chartered Accountants Act, 1949 (as the SA 510 note explains), the Indian text asks for perusal of the audited statements and other relevant documents instead. For the communication that takes place when an auditor changes, see our posts on previous auditor communication and Clause 8 of the First Schedule.

Current-year work as evidence

For current assets and liabilities, current-year work gives some evidence. Collecting opening receivables or paying opening payables during the year says something about existence, rights and obligations, completeness and valuation at the start (A3). Inventory is different: the work on closing inventory tells little about what was on hand at the start, so the auditor may need to observe a current count and reconcile it to opening quantities, test the valuation of opening items, or test gross profit and cut-off (A3).

For non-current items such as fixed assets, investments and long-term debt, the auditor can examine underlying records, and may confirm long-term debt and investments with third parties (A4). Third-party confirmations follow SA 505.

Consistency of accounting policies (paragraph 8)

The auditor needs evidence that policies embedded in the opening balances have been applied consistently in the current year and that any change in policy has been correctly accounted for and presented and disclosed under the applicable framework.

Predecessor's modified opinion (paragraph 9)

If the predecessor's report on the prior period was modified, the new auditor evaluates the matter behind the modification when assessing risks of material misstatement under SA 315 for the current year.

Conclusions and reporting (paragraphs 10-13)

SituationEffect on the opinionParagraph
Cannot get enough evidence on opening balancesQualified opinion or disclaimer, as appropriate10
Opening balances materially misstated and not properly accounted for or disclosedQualified or adverse opinion11
Policies not consistently applied, or change in policy not properly accounted for or disclosedQualified or adverse opinion12
Predecessor's modification still relevant and material to the current periodModify the current opinion13

The modifications follow SA 705. A5 notes that, unless law prohibits it, an opinion may be qualified or disclaimed on the results of operations and cash flows while remaining unmodified on the state of affairs. A6 gives the example of a prior-year scope limitation that has since been resolved, in which case the earlier modification may no longer matter for the current period. The appendix to the standard contains illustrative reports with modified opinions; it shows a qualification where the auditor was appointed after the start of the year and could not observe the opening inventory count, and it carries an "Other Matter" statement about the earlier audit by another auditor.

Illustrative example

Greenfield Foods Pvt Ltd is an invented company; all figures are illustrative. A new firm is appointed in September and the year ended on 31 March, so the opening inventory count was never observed. The firm reads the prior-year audited statements and the predecessor's report, which was unmodified. It checks that closing balances of the prior year agree with the opening ledger. For receivables, it uses collections in April and May. For opening inventory valued at Rs 1.8 crore, it reviews the prior count records, tests the year's purchases and sales and examines gross profit and cut-off. If those procedures give enough comfort, the opinion is unaffected. If they do not, the firm qualifies the opinion on the results and cash flows and explains why in the basis paragraph.

Need help with a change of auditor?

Companies that appoint a new auditor can save time by keeping the previous year's audited statements, schedules, reconciliations and stock records ready. TaxClue's books of accounts compliance support can help you tie closing balances to opening balances and prepare the schedules a first-year auditor will ask for.

Key takeaways

  • A first audit means extra work on opening balances and policy consistency.
  • The new auditor reads the latest statements and the predecessor's report.
  • Inventory usually needs additional procedures because current-year work says little about opening stock.
  • Not getting evidence on opening balances means a qualified opinion or a disclaimer.
  • A material uncorrected misstatement in opening balances means a qualified or adverse opinion.

It applies to an initial engagement: where the prior year was unaudited or audited by a different firm (paragraph 4).

The Indian text does not ask for that; it asks the new auditor to peruse the audited statements and related documents, citing the confidentiality provisions of the Chartered Accountants Act, 1949 (note on modifications).

Collections of receivables give evidence about the opening balance, but audit work on closing stock tells little about stock at the start (A3).

The new auditor evaluates it when assessing risk and modifies the current opinion if the matter remains relevant and material (paragraphs 9 and 13).

Only if it is not properly accounted for or not adequately presented and disclosed; then a qualified or adverse opinion follows (paragraph 12).

The text refers to prior period items disclosed in the current year's Statement of Profit and Loss, citing AS 5 as printed in the standard (paragraph 6(a) and its footnote).
