What it means
Materiality is a judgement about consequence, not just about size. A $50,000 error is trivial in a business earning $80,000,000 of profit and catastrophic in one earning $200,000, so the same number is material in one set of accounts and immaterial in another.
The concept matters because auditing every transaction would be impossibly expensive. Setting a materiality threshold lets the audit team concentrate effort where an error would actually affect a lender, an investor or a board decision.
In practice auditors calculate an overall materiality figure at the start of the audit, often as a percentage of a benchmark such as pre-tax profit, revenue or total assets. They then set a lower working threshold, commonly half to three quarters of that figure, so that several small errors added together do not slip past unnoticed.
Misstatements come in two flavours, and both count. Error means an unintentional mistake such as a miscalculated accrual, while fraud means deliberate manipulation, and auditors are required to consider the risk of both when planning their work.
Size is not the only test. A misstatement can be material because of its nature rather than its value, for example an undisclosed payment to a director, a breach of a loan covenant, or an error that turns a small reported profit into a loss.
Errors found during an audit are not always corrected. Small differences are collected on a schedule of unadjusted items and reviewed together at the end, and management only has to adjust the accounts if the total, or an individual item, crosses the materiality threshold or matters for another reason.
In practice
Real-world examples.
Example
An auditor at a haulage firm finds $18,000 of invoices posted to the wrong month. Against materiality of $190,000 the error is immaterial, so it is logged on the schedule of unadjusted differences rather than forced through as a correction.
Example
A software company capitalises $1,100,000 of development costs that do not meet the criteria for capitalisation. The amount exceeds materiality and turns a reported profit into a loss, so the auditors require the accounts to be restated before signing.
Example
A charity discovers a $30,000 payment to a company owned by a trustee that was never disclosed. Although the amount is far below the calculated threshold, it is treated as material by nature because of the related party relationship.
Think of it
“Material misstatement is an error big enough to matter-affecting user decisions.
Formula
Calculation
A common approach is: overall materiality = benchmark x percentage, where pre-tax profit is often used at around 5%. A distribution company reports pre-tax profit of $4,200,000, so overall materiality is $4,200,000 x 0.05 = $210,000. Performance materiality, set at 75% of that figure, is $210,000 x 0.75 = $157,500, and the auditors use this lower level when testing individual balances. During the audit they find that $260,000 of revenue was recognised in the wrong year. Because $260,000 exceeds the $210,000 threshold, the misstatement is material, and correcting it would reduce pre-tax profit to $4,200,000 - $260,000 = $3,940,000, a fall of roughly 6%.Case study
Seen in the real world.
Kestrel Fabrication is an entirely fictional metalwork business used here to illustrate how materiality works in practice. Its auditors set overall materiality at $210,000 based on 5% of expected pre-tax profit, and performance materiality at $157,500. Testing of stock revealed that finished goods had been valued at selling price rather than cost in one of the three warehouses.
The overstatement came to $268,000. Because this exceeded the overall threshold, the illustrative audit team could not simply note it and move on, and management agreed to adjust the accounts before publication.
The wider lesson in the fictional case was about causes rather than the single number. The same valuation error had existed in a smaller form for two years without crossing the threshold, so the audit team recommended a control change requiring the stock valuation method to be reviewed and signed off annually by the finance director.
Watch out
Common mistakes.
- Assuming that anything below the materiality threshold can be ignored, when several small errors in the same direction can add up to a material total.
- Believing materiality is a fixed legal number, when it is a professional judgement that changes with the business, the year and the benchmark chosen.
- Treating materiality as purely numerical and missing items that are material by nature, such as director transactions or covenant breaches.
Questions
People also ask.
Who decides what is material?
The auditor sets materiality for audit purposes using professional judgement, though management is responsible for producing accounts that are free from material misstatement in the first place.
Does a material misstatement always mean fraud?
No, most material misstatements are honest errors in estimates, cut-off or classification, though auditors must always consider whether fraud could be the explanation.
What happens if management refuses to correct one?
The auditor can issue a modified opinion, either qualified or adverse depending on how pervasive the problem is, which is a serious signal to lenders and investors.
