Exam 10: Tests of Controls
At what stage during the audit is the existence of internal controls tested and how are these tests carried out?
The existence of internal control will usually be tested during the control risk assessment stage.Types of testing the auditor would undertake in evaluating the existence of an internal control include inquiries of entity personnel, inspection of documents and reports, and observation of the application of specific internal control policies and procedures, including walk-throughs.
Tests of the effectiveness and continuity of controls (commonly called operating effectiveness) are undertaken as a test of the controls that are expected to be relied upon.
Outline the factors that will determine whether the auditor has obtained sufficient appropriate evidence to support a particular risk assessment.
There are a number of factors that will determine whether the auditor has obtained sufficient appropriate evidence to support a particular control risk assessment.The auditor requires stronger evidence if the assessed level of control risk is low rather than medium.If control risk is high, the auditor does not have to gather evidence to support this assessment, as they do not intend to rely on controls.They will gather their evidence via substantive testing.Other factors that the auditor considers in determining whether the tests of controls have yielded sufficient appropriate evidence include: type and source of evidence (some types of audit tests provide stronger evidence); timeliness of evidence; and interrelationship with other evidence (does all evidence point to the same conclusion?).
In a computer information system control procedures that provide reasonable assurance that the recording, processing and reporting of data are properly performed for specific applications are known as:
A
What is the purpose of the preliminary assessment of control risk?
The audit test that would normally be regarded as a test of control is:
Testing the work of the internal auditors is least likely when the external auditor has decided that:
Assessing control risk at a level below high most likely would involve:
To determine whether the internal control structure policies and procedures operate effectively to minimise errors of failure to invoice a shipment, the auditor would select a sample of transactions from the population represented by the:
External auditors have a duty to communicate in writing significant deficiencies in internal control to those charged with governance.Which of the following is unlikely to be relevant when determining whether a 'significant deficiency' exists?
When tests of controls are not performed while obtaining an understanding under the predominantly substantive approach:
'Enquiring' is a control test used by auditors.It requires the auditor to:
Which of the following is a limitation of using 'observation' for tests of controls?
When an auditor is designing tests of the operational effectiveness of controls they must decide their nature, timing and extent.Explain what each of these concepts mean and why they are important in designing these tests.
The statement that is accurate concerning audit testing is:
After performing additional tests of controls, the auditor reassesses control risk from the initial planning level of slightly below maximum to moderate.The auditor should now:
For the following potential misstatements for cash payments, identify a necessary control and a test of the operational effectiveness of that control.
1 a cash payment may be made for an unauthorised purpose.
2 an invoice may be paid twice.
3 a cheque may be issued for the wrong amount.
4 a cash payment transaction may not be recorded.
Which of the following is not an advantage of the test data approach?
Which of the following would be a necessary control to avoid an invoice being paid twice?
