(b) ISA 540 Audit of Accounting Estimates requires that auditors should obtain sufficient audit evidence as to whether an
accounting estimate, such as a warranty provision, is reasonable given the entity’s circumstances, and that disclosure is
appropriate. One, or a combination of the following approaches should be used:
Review and test the process used by management to develop the estimate
– Review contracts or orders for the terms of the warranty to gain an understanding of the obligation of Island Co
– Review correspondence with customers during the year to gain an understanding of claims already in progress at the
year end
– Perform. analytical procedures to compare the level of warranty provision year on year, and compare actual to budgeted
provisions. If possible disaggregate the data, for example, compare provision for specific types of machinery or customer
by customer
– Re-calculate the warranty provision
– Agree the percentage applied in the calculation to the stated accounting policy of Island Co
– Review board minutes for discussion of on-going warranty claims, and for approval of the amount provided
– Use management accounts to ascertain normal level of warranty rectification costs during the year
– Discuss with Kate Shannon the assumptions she used to determine the percentage used in her calculations
– Consider whether assumptions used are consistent with the auditors’ understanding of the business
– Compare prior year provision with actual expenditure on warranty claims in the accounting period
– Compare the current year provision with prior year and discuss any fluctuation with Kate Shannon.
Review subsequent events which confirm the estimate made
– Review any work carried out post year end on specific faults that have been provided for. Agree that all costs are included
in the year end provision.
– Agree cash expended on rectification work in the post balance sheet period to the cash book
– Agree cash expended on rectification work post year end to suppliers’ invoices, or to internal cost ledgers if work carried
out by employees of Island Co
– Read customer correspondence received post year end for any claims received since the year end.

正确答案：
(b) The strategic apex is the highest level of the organisation and is therefore the highest level of management. This part ensures that the organisation’s mission is followed and manages the relationship with the environment.
The operating core is the part that represents the productive activity of the organisation, gathering inputs and, through conversion, turns them into outputs.
The middle line represents that part of the organisation where the middle managers operate. The role of this part is to turn the instructions of the strategic apex into activities for the operating core.
The technostructure includes the staff who provide a technical or supportive activity but which are not a part of the core activities. This part of the organisation includes the engineering, accounting and human resource departments.
The support staff carry out the ancillary activities that are neither part of the core nor the technostructure. Support staff have no role in the direct activities of the organisation: these activities include catering and public relations.(Students may draw the appropriate diagram)
