Is evidence generally persuasive or conclusive?
Persuasive
So sometimes need to preform more than one substantive procedure to address a given risk
Two traditional categories of Computer Assisted Audit Technique (CAAT)
Test data
Audit software
Test data: Description
Auditor data put into client’s system
Real or dummy data
Live or copy system
E.g. Entering timesheet with hours outside the normal range to check system rejects it
Entering valid purchase invoice to check that it is allocated to the correct account
Audit Software: Description
Client data put into auditor’s system
E.g. Reperformance of addition or ageing of transactions
Preparation of reports
Calculations of ratios
Sample selection
Test data: Use
Test controls in the system
Audit Software: Use
- Basic data analysis
- Substantive testing
Three areas data analytics can assist with
- Transaction analysis
E.g. matching purchase orders, goods received notes, invoices - Judgmental areas
E.g. sensitivity analysis to test assumptions on net realisable value of inventory - Analytical procedures
E.g. analysing revenue trends by product or region
How may data analytics be presented?
Bar or pie charts
IAS (UK) 520 states analytical procedures can be used as substantive procedures. Though it is dependent on what sort of factors
Strength/compatibility of relationships
Reliability of data
Level of disaggregation of the data available
Knowledge of client
What extra step has to be done during ARs in the evidence stage?
Determining whether expected variations are acceptable (based on materiality)
If not, seek further evidence
How can an auditor seek further evidence if an AR doesn’t provide enough evidence?
- Management enquiries
- Corroborate to other evidence
Overstatement direction of testing
- Figure in accounts
- Intermediate documentation
- Supporting evidence
Understatement testing direction
- Reciprocal population
- Supporting evidence
- Intermediate documentation
- Figure in accounts
Examples of accounting estimated
Depreciation
Allowance for receivables
Provisions
Why are estimates more risky?
- Subjective
- Management bias
