Final Analytical Procedures and Overall Review in ACCA Audit and Assurance

Updated 11 October 2026 · Fact-checked

Final analytical procedures (ISA 520) are comparisons and ratio checks done near the end of the audit to test whether the financial statements agree with your understanding of the entity. You then evaluate uncorrected misstatements (ISA 450) and judge whether the evidence is sufficient and appropriate before concluding.

Understand Final Analytical Procedures and Overall Review

At the end of the audit you stop testing individual balances and look at the whole picture. The question is simple: do the financial statements make sense, and do they agree with what you learned about the client during the audit?

Final analytical procedures are required by ISA 520. You compare figures with prior years, budgets, industry data and expectations, and you look at relationships between figures, such as gross margin or receivables days. If the final numbers are different from your expectations, you investigate. If you find a previously unrecognised risk of material misstatement, you must revise your assessment and consider whether more procedures are needed.

These are not the same as planning analytical procedures. At planning, you use them to identify risk areas. At the end, you use them as an overall check. The data is now final, adjusted and audited, so unexplained fluctuations are more worrying.

The overall review also covers misstatements. Under ISA 450 you accumulate all misstatements found, except those that are clearly trivial. You ask management to correct them. You then evaluate the uncorrected misstatements, individually and in total, against materiality. You consider their size, their nature and their circumstances. A small misstatement can still be material if it hides a trend, changes a loss into a profit, affects covenant compliance or involves directors.

Finally, you conclude on whether you have obtained sufficient appropriate audit evidence (ISA 330) and whether the financial statements are prepared in accordance with the framework. You review the audit file, check that all work is complete and reviewed, and consider the implications for the auditor's report. Materiality may need revising if circumstances changed during the audit.

Key rules to remember

Final analytical procedures purpose: Final figures vs. expectations → unexplained differences → investigate → revise risk assessment if needed; ISA 520 requires analytical procedures near the end that help form an overall conclusion on the financial statements.
Trivial misstatements: Clearly trivial = clearly inconsequential, whether judged by size, nature or circumstances; Set a threshold at planning. It is usually well below materiality. It is not the same as materiality.
Uncorrected misstatements test: Total uncorrected misstatements (by effect on profit, assets, liabilities) vs. overall materiality and performance materiality; Assess both individually and in aggregate, plus qualitative factors. Also assess the effect of uncorrected prior-period misstatements.
Common ratio checks: Gross margin = gross profit ÷ revenue × 100; Receivables days = receivables ÷ revenue × 365; Inventory days = inventory ÷ cost of sales × 365; Current ratio = current assets ÷ current liabilities; Compare with prior year and industry. Calculate them on final figures.
Auditor's response to uncorrected misstatements: Management refuses to correct → communicate to those charged with governance → request written representation → consider modified opinion if material; ISA 450 requires communication of uncorrected misstatements unless prohibited by law, and a written representation on their effect.

How to solve Final Analytical Procedures and Overall Review questions

Use this method for any question on final review, final analytical procedures or misstatement evaluation.

1Read the scenario and identify the stage: you are at the end of the audit, using final figures.
2Work out the expectation. Calculate the key ratios or changes (margins, days, growth) and compare with prior year, budget and your knowledge of the client.
3Flag unexpected movements. For each, give a possible cause (error, fraud, change in business, accounting policy change) and the audit procedure to follow up.
4List the misstatements. Separate corrected from uncorrected, and note which are clearly trivial.
5Compare uncorrected misstatements with materiality, in total and one by one. Add qualitative factors such as profit-to-loss swings, covenants, directors' transactions or trends.
6Decide the action: ask management to adjust, communicate to those charged with governance, obtain a written representation, or consider modifying the opinion.
7Conclude on sufficiency and appropriateness of evidence, and say what you would do if evidence is lacking (extend procedures or consider a limitation of scope).
8Link to the report: state the likely opinion and any further completion steps such as file review and going concern.

Quickest way: Calculate, explain, conclude

When to use it: Use it for Section B or C questions with a set of ratios or a schedule of misstatements and little time.

Compute the two or three most relevant ratios or percentage changes first. Write the figures down.
Compare each to materiality or expectation in one line: 'This is X% higher, which is unusual because…'.
For every unexplained item write cause plus procedure: 'Possible overstatement of revenue; perform cut-off testing.'
Add up uncorrected misstatements and compare the total with materiality. Then add one qualitative point.
Finish with a clear conclusion: 'Request adjustment; if refused, consider a qualified opinion if material.'

Common mistakes in Final Analytical Procedures and Overall Review

Treating final analytical procedures as identical to planning analytical procedures.
Both use ratios and trends, so they look the same.
Fix: State the purpose. At planning they identify risk. At the end they are an overall check that the statements agree with your understanding and may reveal unrecognised risks.
Saying a misstatement is immaterial only because it is below overall materiality.
Students look only at the number.
Fix: Assess the total of uncorrected items and the qualitative factors, such as a change from loss to profit, covenants, trends, or involvement of management.
Confusing 'clearly trivial' with 'immaterial'.
Both sound like 'small'.
Fix: Trivial items are clearly inconsequential and are not accumulated. Items above that threshold are accumulated, even if later judged immaterial.
Listing ratios without explaining causes or follow-up procedures.
Calculation feels like the answer.
Fix: For each unusual movement give a reason and a specific audit procedure. Marks are for interpretation.
Forgetting to communicate uncorrected misstatements and obtain a representation.
Students stop at 'ask management to adjust'.
Fix: Add: communicate to those charged with governance, request correction, and obtain a written representation on the effect of the uncorrected items.
Concluding evidence is sufficient without checking the whole file.
Students focus on balances rather than overall review.
Fix: Mention file review, resolution of open points, and consideration of whether all significant risks were addressed before issuing the opinion.

Worked examples

Example 1

Wexford Ltd has revenue of $8,000,000 (prior year $6,400,000) and cost of sales of $5,600,000 (prior year $4,800,000). Receivables are $2,000,000 (prior year $1,280,000). Use final analytical procedures to identify matters for follow-up. Use 365 days.

Show the solution

Revenue growth = (8,000,000 − 6,400,000) ÷ 6,400,000 = 25%.
Gross margin this year = (8,000,000 − 5,600,000) ÷ 8,000,000 = 2,400,000 ÷ 8,000,000 = 30%.
Gross margin last year = (6,400,000 − 4,800,000) ÷ 6,400,000 = 1,600,000 ÷ 6,400,000 = 25%.
Receivables days this year = 2,000,000 ÷ 8,000,000 × 365 = 91.25 days.
Receivables days last year = 1,280,000 ÷ 6,400,000 × 365 = 73 days.
Interpretation: margin rose 5 percentage points and receivables days rose 18.25 days. Together with 25% revenue growth this suggests possible revenue overstatement, such as fictitious sales or cut-off errors, and possible under-recovery of receivables.
Follow-up: perform cut-off testing around the year end, review credit notes after the year end, test receivables recoverability and subsequent cash receipts, and ask management about price or mix changes. If a new risk of material misstatement emerges, revise the risk assessment and extend procedures.

Answer: Revenue up 25%, gross margin up from 25% to 30%, receivables days up from 73 to 91.25. These are unexpected and indicate a risk of revenue overstatement and weak receivables, so investigate with cut-off, post year-end receipts and credit note testing.

Example 2

At the end of the audit of Karter Co, overall materiality is $100,000. Uncorrected misstatements: (1) inventory overstated by $40,000, (2) accrued expenses understated by $35,000, (3) revenue overstated by $20,000 from sales recorded early. Draft profit before tax is $130,000. Management refuses to adjust. Evaluate and state the action.

Show the solution

Total effect on profit: inventory overstated reduces cost of sales too little, so profit is overstated by $40,000. Understated accruals overstate profit by $35,000. Revenue overstated by $20,000 overstates profit by $20,000. The total is $95,000. This ignores the matching cost of sales on the early sales, which we do not know.
Compare with materiality: $95,000 is below $100,000 individually and in total, but very close, at 95% of materiality.
Adjusted profit would be $130,000 − $95,000 = $35,000. This is a fall of about 73% from the draft figure, so the effect on profit is large relative to the result.
Qualitative factors: all three items overstate profit, which suggests possible bias. The revenue item is a cut-off error that may indicate a control weakness. Check whether there are covenants or profit targets.
Also consider the risk of undetected misstatements: with the total so near materiality, undetected errors could push the total over the limit.
Action: ask management to correct again, communicate the items to those charged with governance, and request a written representation on the effect of uncorrected items. Consider extending testing in inventory, accruals and cut-off.
If management still refuses and the total is judged material, including the qualitative factors, issue a qualified opinion (material but not pervasive) on the financial statements.

Answer: Profit is overstated by $95,000, just under materiality of $100,000 but about 73% of draft profit. Because all errors overstate profit and risk of further errors is high, treat as likely material: communicate to those charged with governance, obtain a representation, extend work, and qualify the opinion if not corrected.

Exam tips

Show calculations first and interpretation second. Marks usually go to the explanation of what a movement means and the audit follow-up.
In misstatement questions, always total the uncorrected items and compare with materiality, then add a qualitative factor. Do not stop at the number.
Name the correct ISA where it helps: ISA 520 for final analytical procedures and ISA 450 for misstatements. Do not quote paragraph numbers.
For objective test questions, remember that final analytical procedures help form an overall conclusion, and that clearly trivial items are not accumulated. Wrong answers often swap these.
Finish every written answer with a clear action or conclusion: adjust, communicate, represent, or modify the opinion.

Final Analytical Procedures and Overall Review: frequently asked questions

What is the purpose of final analytical procedures in an audit?

They help you form an overall conclusion on whether the financial statements are consistent with your understanding of the entity. They can also reveal a previously unrecognised risk of material misstatement. If they do, you revise your risk assessment and perform further procedures.

How is the overall review different from the final analytical procedures?

Final analytical procedures are one part of the overall review. The overall review also includes evaluating misstatements, assessing whether evidence is sufficient and appropriate, checking disclosures and presentation, and reviewing the audit file.

What do I do with uncorrected misstatements under ISA 450?

You communicate them to management and ask for correction. If management refuses, you tell those charged with governance, obtain a written representation, and evaluate their effect against materiality. If they are material, you consider modifying the audit opinion.

Can a small misstatement still be material?

Yes. Size is only one factor. A small item can be material if it turns a loss into a profit, hides a trend, breaches a covenant or involves management. Always add qualitative factors to your answer.
