(ii) On 1 July 2006 Petrie introduced a 10-year warranty on all sales of its entire range of stainless steelcookware. Sales of stainless steel cookware for the year ended 31 March 2007 totalled $18·2 million. Thenotes to the financial statements disclose

正确答案：
(ii) 10-year guarantee
$18·2 million stainless steel cookware sales amount to 43·1% of revenue and are therefore material. However, the
guarantee was only introduced three months into the year, say in respect of $13·6 million (3/4 × 18·2 million) i.e.
approximately 32% of revenue.
The draft note disclosure could indicate that Petrie’s management believes that Petrie has a legal obligation in respect
of the guarantee, that is not remote and likely to be material (otherwise no disclosure would have been required).
A best estimate of the obligation amounting to 5% profit before tax (or more) is likely to be considered material, i.e.
$90,000 (or more). Therefore, if it is probable that 0·66% of sales made under guarantee will be returned for refund,
this would require a warranty provision that would be material.
Tutorial note: The return of 2/3% of sales over a 10-year period may well be probable.
Clearly there is a present obligation as a result of a past obligating event for sales made during the nine months to
31 March 2007. Although the likelihood of outflow under the guarantee is likely to be insignificant (even remote) it is
probable that some outflow will be needed to settle the class of such obligations.
The note in the financial statements is disclosing this matter as a contingent liability. This term encompasses liabilities
that do not meet the recognition criteria (e.g. of reliable measurement in accordance with IAS 37 Provisions, Contingent
Liabilities and Contingent Assets).
However, it is extremely rare that no reliable estimate can be made (IAS 37) – the use of estimates being essential to
the preparation of financial statements. Petrie’s management must make a best estimate of the cost of refunds/repairs
under guarantee taking into account, for example:
■ the proportion of sales during the nine months to 31 March 2007 that have been returned under guarantee at the
balance sheet date (and in the post balance sheet event period);
■ the average age of cookware showing a defect;
■ the expected cost of a replacement item (as a refund of replacement is more likely than a repair, say).
If management do not make a provision for the best estimate of the obligation the audit opinion should be qualified
‘except for’ non-compliance with IAS 37 (no provision made). The disclosure made in the note to the financial
statements, however detailed, is not a substitute for making the provision.
Tutorial note: No marks will be awarded for suggesting that an emphasis of matter of paragraph would be appropriate
(drawing attention to the matter more fully explained in the note).
Management’s claim that the obligation cannot be measured with sufficient reliability does not give rise to a limitation
on scope on the audit. The auditor has sufficient evidence of the non-compliance with IAS 37 and disagrees with it.
