Chapter 7
Assertions and audit evidence
1 Introduction
When a figure appears in financial statements it is making a number of assertions. For example, if the receivables figure is $2,453,000, the figure is asserting:
The amount has been properly valued
The receivables are owned by the company
The receivables exist
The receivables are complete
The amount is indeed properly described as receivables.
It is not possible to simply audit $2,453,000 ‘in one go’: each financial statement assertion requires audit evidence.
2 Assertions about classes of transactions and events and related disclosures
These assertions relate to theperiod under audit:
Occurrence– transactions and events that have been recorded or disclosed have occurred and pertain to the entity.
Completeness– all transactions and events that should have been recorded/disclosed have been recorded/disclosed.
Accuracy – amounts have been recorded appropriately and related disclosures have been properly measured and described.
Cut-off – transactions and events have been recorded in the correct accounting period.
Classification – transactions and events have been recorded in the proper accounts.
Presentation – transactions and events are appropriately aggregated (or disaggregated) and clearly described. Related disclosures are relevant and understandable.
3 Assertions about account balances and related disclosures
These assertions relate to theperiod end:
Existence – assets, liabilities and equity interests exist.
Rights and obligations – the entity holds or controls the rights to assets, and liabilities are the obligations of the entity.
Completeness – all assets, liabilities and equity interests that should have been recorded have been recorded and all related disclosures included.
Accuracy, valuation and allocation – assets, liabilities and equity interests are included at appropriate amounts and any resulting valuation or allocation adjustments are appropriately recorded Related disclosures are appropriately measured and described.
Classification – assets, liabilities and equity interests have been recorded in the proper accounts.
Presentation – assets, liabilities and equity interests are appropriately aggregated (or disaggregated) and clearly described. Related disclosures are relevant and understandable.
Learnthe assertions:
Note that completeness, accuracy, classification and presentation are relevant toboth'transactions and events' and 'account balances' and their related disclosures.
Understand that occurrence and cut-off relateonlyto transactions and events.
Understand that existence, rights and obligations and valuation and allocation relateonlyto account balances.
4 Audit evidence
4.1 Audit procedures for obtaining audit evidence
These are the possible procedures:
Inspection
Observation
External confirmation
Recalculation
Reperformance
Analytical procedures
Enquiry
For the sake of easy learning they are sometimes written to (almost) form the vowels AEIOU:
Analytical procedures
Enquiry and confirmation
Inspection
Observation
RecalcUlation and reperformance
There are no methods to collect evidence that cannot be categorised under one of these headings.
Note from the following examples that:
Analytical procedures, which concern monetary amounts, do not apply to controls.
Observation, which means looking at a process or procedure, is used in tests of controls.
4.2 Examples of evidence collecting procedures
Procedure | Example of use in tests of control | Example of use in substantive procedures |
|---|---|---|
Analytical procedures | – | Comparison of receivables collection period from one year to the next to test the assertion of valuation. |
Enquiry and confirmation | Ask the sales order clerk if he/she performs a credit check before accepting an order. | Ask the directors if all liabilities have been included in the financial statements to test the assertion of completeness. |
Inspection | Inspect times sheets to ensure that they have been signed by the supervisor as authorisation. | Inspect computers in the office to test the assertion of existence. |
Observation | Observe warehouse staff counting goods as they arrive to ensure the quantity is as ordered. | Not applicable |
Recalculation and reperformance | Reperform the bank reconciliation to ensure that it was carried out correctly. | Recalculate the year-end allowance for irrecoverable debts based on the aged analysis of receivables to test the assertion of valuation |
Note that:
For a test of control, enquiryalonewould never be sufficient to conclude that a control is operating effectively.
Substantive procedures are directed to specific assertions.
4.3 Sufficient, appropriate audit evidence
So now we know the various procedures to obtain audit evidence, but how much audit evidence is needed? The sufficiency and appropriateness of audit evidence are interrelated.
Sufficiencyrelates to thequantityof audit evidence. The quantity of audit evidence needed is affected by the auditor’s assessment of the risks of misstatement (the higher the assessed risks, the more audit evidence is likely to be required) and also by the quality of such audit evidence (the higher the quality, the less may be required). Obtaining more audit evidence, however, may not compensate for its poor quality.
Appropriatenessrelates to thequalityof audit evidence - itsrelevance(ie to the financial statement assertions) andreliability. With respect to thereliabilityof audit evidence we can say that, in general:
External evidence is stronger than internal evidence.
Written is stronger than oral.
Evidence is better if the internal control system is strong.
Evidence obtained directly by the auditor is better than evidence obtained via the client.
Originals are better than photocopies.
Therefore, a director simply telling the auditor something is very weak evidence (internal, oral). A bank writing to the auditor to confirm the bank balance is very strong evidence (written, external, obtained directly by the auditor).
