Evaluating Misstatements and Audit Documentation Review (SA 450)

Updated 4 October 2026 · Fact-checked

SA 450 requires the auditor to accumulate misstatements found during the audit, except clearly trivial ones, ask management to correct them, and then evaluate the uncorrected ones, alone and together, against materiality before forming the opinion. Finally, the auditor reviews the work and documentation done.

Understand Evaluating Misstatements and Audit Documentation Review

During an audit you find errors in the financial statements. A misstatement is a difference between the amount, classification, presentation or disclosure reported and what the framework requires. It can arise from error or fraud.

You do not ignore small items, and you do not chase every rupee either. SA 450 asks you to accumulate all misstatements found during the audit, except those that are clearly trivial. Clearly trivial is a much lower bar than materiality. Such matters are clearly inconsequential, whether taken individually or together, and whether judged by size, nature or circumstances. If you are unsure whether an item is clearly trivial, treat it as not trivial.

Once accumulated, you tell management on a timely basis and ask them to correct the items. If management corrects them, you perform further procedures to confirm the corrections are complete and accurate. If management refuses, you ask for its reasons and take them into account when judging whether the statements are free from material misstatement.

Before evaluating the uncorrected misstatements, you reassess materiality, because the figures or the entity's results may have changed from planning. You then check whether the uncorrected misstatements are material, individually or in aggregate. Size is one test. Nature also matters: a small misstatement that turns a loss into a profit, hides a covenant breach, or affects a sensitive disclosure can be material. You also consider the effect of prior-period uncorrected items.

SA 450 requires you to conclude whether the uncorrected misstatements are material, individually or in aggregate, and to consider their effect on the financial statements as a whole. You use professional judgement for this, by size and by nature. SA 450 does not itself set the opinion. The opinion is determined under SA 700 and SA 705. If management corrects the items, no modification is needed on their account. If you conclude that the items are material and they remain uncorrected, an unmodified opinion would not be appropriate, and under SA 705 you give a qualified opinion if the effect is material but not pervasive, and an adverse opinion if it is material and pervasive.

After you have evaluated and concluded, you communicate the uncorrected misstatements to those charged with governance, with their effect on the opinion, and ask for correction. Then you request a written representation from management and, where appropriate, those charged with governance, on whether they believe the effects of uncorrected misstatements are immaterial, and you attach a summary of the items to it. Before reporting, the engagement partner reviews the work and the documentation, and you record the summary and your conclusion in the file.

Key rules to remember

Clearly trivial (conceptual relationship, not a formula): Clearly trivial is well below materiality (far smaller, not just slightly smaller); SA 450 sets no formula or percentage for this. It is a conceptual relationship, and the threshold is set by the auditor's own judgement. It is not the same as performance materiality. Doubt means the item is not trivial.
Aggregate uncorrected misstatements: Aggregate view = uncorrected factual + judgmental + projected misstatements, considered by class of transactions, account balance and disclosure, and also in aggregate; SA 450 does not prescribe a netting formula. The auditor considers the effect of uncorrected misstatements by class of transactions, account balance and disclosure, as well as in aggregate. As a working aid in numerical questions, you can add each item with its sign (overstatements of profit as plus, understatements of profit as minus) to get a net effect, and also note the gross amounts. Factual: no doubt. Judgmental: differences in estimates or policies. Projected: auditor's best estimate of misstatement in a population from sample results.
Evaluation test: Uncorrected misstatements (individual and aggregate) vs. materiality (reassessed); SA 450 requires you to conclude, using judgement, whether the uncorrected misstatements are material, individually or in aggregate, considering the effect on the financial statements as a whole. Consider nature as well as amount. The opinion is then determined under SA 700 and SA 705. If management corrects the items, no modification is needed. If the items are material and remain uncorrected, SA 705 applies: qualified opinion if material but not pervasive, adverse opinion if material and pervasive.
Communication duty: Communicate all accumulated misstatements on a timely basis to the appropriate level of management and ask for correction; after evaluating, communicate the uncorrected ones to those charged with governance; Communication to those charged with governance covers the uncorrected misstatements, with the effect they may have on the opinion, unless law prohibits. It comes after your evaluation and before you obtain the written representation.

How to solve Evaluating Misstatements and Audit Documentation Review questions

Use this order for any question on evaluating misstatements, whether it is a case study or a theory answer.

1Identify each item found and classify it as factual, judgmental or projected.
2Decide if it is clearly trivial. If it is, it need not be accumulated. If doubtful, accumulate it.
3Accumulate the rest and communicate them to the appropriate level of management on a timely basis. Ask for correction.
4If management corrects, perform further procedures to check the corrections are complete and accurate. If not, ask for reasons.
5Reassess materiality, then compare individual and aggregate uncorrected misstatements with it. Consider nature, such as turning loss into profit or affecting covenants, and the effect on the financial statements as a whole.
6Use judgement to conclude whether the uncorrected misstatements are material. If they are immaterial, they do not stand in the way of an unmodified opinion. If they are material and remain uncorrected, the opinion is determined under SA 700 and SA 705: qualified if not pervasive, adverse if pervasive. If management corrects them, no modification is needed.
7Communicate the uncorrected misstatements to those charged with governance, with their effect on the opinion, and ask for correction.
8Request a written representation from management and, where appropriate, those charged with governance, on whether they believe the effects of uncorrected misstatements are immaterial. Attach a summary of the items.
9Document the threshold, all accumulated items, the actions taken and the conclusion. The partner reviews before the report is signed.

Quickest way: Total, compare, then check nature

When to use it: Use for numerical MCQs and short case questions with limited time.

Strike out items below the clearly trivial limit first. They drop out of the schedule.
Add the remaining items with signs: overstatements of profit as plus, understatements of profit as minus. This gives the net effect. Also note the gross overstatements and gross understatements.
Compare both the net effect and the gross amounts with the materiality figure given.
Ask one more question: does the nature change the answer? Look for loss to profit, ratio breach or fraud.
In written answers, use this layout: Provision, Facts, Conclusion. Name SA 450, apply the figures, then state the opinion effect. A structured answer like this generally helps presentation and keeps you from missing a point.
In MCQs, remember that clearly trivial is not the same as immaterial, and that the auditor communicates rather than corrects the books.

Common mistakes in Evaluating Misstatements and Audit Documentation Review

Treating clearly trivial as equal to materiality or performance materiality.
All three are thresholds, so they blur together.
Fix: Remember that clearly trivial is far below materiality. Items under it are ignored. Items above it are accumulated even if immaterial.
Saying the auditor corrects the misstatements in the books.
Students confuse the auditor's role with management's.
Fix: Management prepares the statements. The auditor communicates, requests correction and evaluates what remains.
Judging materiality only on amount.
Numerical questions push you towards a simple comparison.
Fix: Always add one line on nature and circumstances, for example a small error that converts a loss into a profit.
Forgetting to reassess materiality before evaluation.
Students assume the planning figure is final.
Fix: State that materiality is revised if the actual results or circumstances differ from those assumed at planning.
Omitting the written representation and communication with those charged with governance.
Focus stays on the quantitative evaluation.
Fix: End every answer with the communication, the representation and the documentation steps.
Netting overstatements and understatements without thought.
It looks neat to offset them.
Fix: Consider both the net and the gross effect. Offsetting items may hide misclassification or bias, and some line items may be material alone.

Worked examples

Example 1

Overall materiality is ₹10,00,000. Using his own judgement, the auditor treats items up to ₹10,000 (1% of materiality) as clearly trivial. This is not a prescribed percentage. Misstatements found: (a) expenses overstated ₹4,000; (b) purchases understated ₹6,00,000, which overstates profit; (c) provision understated ₹3,50,000 (judgmental); (d) revenue overstated ₹1,20,000. Management corrects only (b). Evaluate whether uncorrected misstatements are material.

Show the solution

Item (a) is ₹4,000, below the auditor's own limit of ₹10,000. It is clearly trivial and is not accumulated.
Item (b) is corrected by management. The auditor checks the correction is complete and accurate. Because it is corrected, it is excluded from the uncorrected total.
Uncorrected and accumulated items: (c) ₹3,50,000 understatement of provision, which overstates profit by ₹3,50,000; (d) ₹1,20,000 revenue overstatement, which overstates profit by ₹1,20,000.
Both items overstate profit, so they carry the same sign and add up. As a working aid, the net effect on profit = ₹3,50,000 + ₹1,20,000 = ₹4,70,000 overstatement. There are no understatements of profit among the accumulated items, so the gross overstatement is also ₹4,70,000 and the gross understatement is nil.
Reassess materiality before comparing. Assume here that it is unchanged at ₹10,00,000.
Compare with materiality: ₹4,70,000 (net and gross) is below ₹10,00,000. Quantitatively it is not material.
Consider nature and prior periods: check whether the items change a loss to profit or breach a covenant, and whether any uncorrected misstatements from prior periods add to the effect.
Item (c) is judgmental, as it arises from an estimate. Assess whether it indicates management bias in the estimate, and whether the direction of the estimates is consistently favourable to reported profit. The conclusion depends on this bias assessment as well as on the nature checks above.
If none of these checks changes the picture, conclude that the uncorrected misstatements are immaterial.
Communicate (c) and (d) to those charged with governance, request the written representation from management and, where appropriate, those charged with governance, and document.

Answer: The uncorrected misstatements overstate profit by ₹4,70,000 (net and gross), which is below materiality of ₹10,00,000 (reassessed and assumed unchanged). Item (a) of ₹4,000 is clearly trivial and is not accumulated. The final conclusion depends on the assessment of management bias in the judgmental item (c), on the nature check, and on any prior-period uncorrected items. If these show no concern, the misstatements are not material and an unmodified opinion can be considered, with the opinion determined under SA 700 and SA 705.

Example 2

During the final review, an auditor finds uncorrected misstatements well below materiality. However, they turn the company's reported loss into a small profit. Management refuses to correct them. What should the auditor do?

Show the solution

Provision: SA 450 requires evaluating uncorrected misstatements considering both size and nature, and circumstances.
Facts: the amounts are small, but they change a loss into a profit. This is a qualitative factor, as users may be sensitive to the result.
Ask management for its reasons for not correcting, and take them into account. Continue to request correction.
Reassess materiality, then use professional judgement to decide whether the misstatements are material by nature, individually and in aggregate, and what their effect is on the financial statements as a whole. A misstatement that reverses a loss may well be material despite its size.
If management corrects the items after all, perform procedures to check the corrections. No modification is needed on their account.
If they remain uncorrected, communicate them to those charged with governance, with their effect on the opinion, and request correction.
Request the written representation from management and, where appropriate, those charged with governance. Document the evaluation and the conclusion.

Answer: The auditor uses professional judgement to decide whether the misstatements are material by nature, even though the amounts are below the quantitative threshold. SA 450 requires this conclusion on materiality. The opinion is then determined under SA 700 and SA 705. If management corrects the items, no modification is needed. If the auditor concludes they are material and they remain uncorrected, an unmodified opinion would not be appropriate, and SA 705 applies: a qualified opinion if the effect is material but not pervasive, or an adverse opinion if it is material and pervasive. After evaluating, the auditor communicates the uncorrected items to those charged with governance and obtains the written representation.

Exam tips

Write the full chain in theory answers: accumulate, communicate to management, request correction, reassess materiality, evaluate, communicate uncorrected items to those charged with governance, obtain representation, document.
In numerical questions, show the clearly trivial screen first, then the total. Showing each step clearly makes your working easy to follow.
Always add a line on qualitative factors. It often decides the conclusion in case studies.
In MCQs, watch for traps such as 'auditor adjusts the books' or 'clearly trivial means immaterial'. Both are wrong.
Link the answer to SA 700 and SA 705 when uncorrected misstatements are material, and to SA 230 for documentation.

CA FinalSA 450: Evaluation of Misstatements Identified During the Audit

Evaluating Misstatements and Audit Documentation Review: frequently asked questions

What does clearly trivial mean in SA 450?

It means matters that are clearly inconsequential, individually or in aggregate, judged by size, nature or circumstances. The threshold is much lower than materiality. If there is any doubt, the item is not clearly trivial.

Does the auditor have to correct misstatements found?

No. Management is responsible for the financial statements. The auditor communicates the misstatements and asks management to correct them, then evaluates any that remain.

Why is a written representation needed on uncorrected misstatements?

The auditor requests it from management and, where appropriate, those charged with governance. It records their belief that the effects of uncorrected items are immaterial, individually and in aggregate. A summary of the items is attached. It supports the auditor's conclusion but does not replace the auditor's own evaluation.

What is a projected misstatement?

It is the auditor's best estimate of misstatement in a population, worked out by extrapolating misstatements found in a sample. It is included with factual and judgmental misstatements when evaluating the total.
