Revenue 1% – 2% An item of revenue is material if it is at least 1% or 2% of
annual sales revenue.
Pre-tax
profit
5% – 10% An item is material if it is at least 5% or 10% of reported
pre-tax profit.
Total
assets
5% – 10% A balance is material if it represents at least 5% or 10% of
total assets.
The ‘danger’ of materiality thresholds is that they are used simply to ‘measure’
whether an item is material, without considering important other factors as well.
Other factors that the auditor should consider in evaluating materiality may include
the following:
The nature of the item involved – The valuations of some items in the financial
statements are more subjective than others, and depend on estimation. The more
subjective the item, the more flexible the auditor should be in assessing the
materiality of possible misstatements. The auditor will have to take a very
different view on materiality when considering a warranty provision (which is a
subjective estimate), compared with the approach taken when auditing share
capital, which is capable of precise measurement.
The significance of the item – Some items may be insignificant in terms of their
monetary amount, but may nevertheless be of particular interest to the users of
the financial statements. An example might be bonus payments to directors.
The impact of the item on the view presented by the financial statements. A
small and apparently insignificant error or omission may be material if, by
correcting it:
− a reported profit is converted into a reported loss, or
− the correction significantly alters the trend of profits (growth rate in profits)
over the past few financial years.
3.3 ISA 320: Audit materiality
ISA 320 requires the auditor to apply the concept of materiality:
when planning and performing the audit, and
when evaluating the effect of misstatements on the financial statements and
therefore on his audit opinion (covered in a later chapter under ISA 450
Evaluation of misstatements identified during the audit).
At the planning stage, the auditor must determine materiality for the financial
statements as a whole. As discussed above, this is often set as materiality thresholds.
If lower thresholds are required for some areas (for example, directors’
remuneration) these must also be set at this stage.
The auditor must also set what ISA 320 refers to as performance materiality.
Performance materiality recognises the fact that if all areas of the audit are carried
out to detect all errors/omissions under the (overall) materiality level, that objective
could be achieved, but when all the individual immaterial errors/omissions are
added together, overall materiality could in fact be breached. Performance
materiality is a way of taking this risk into account and will be set at a lower figure
