(187 cards)
1
Q
what is the definition of internal controls?
A
whole system of controls, financial and otherwise, established by the management in order to carry out the business of the enterprise in an orderly and efficient manner, ensure adherence to management policies, safeguard the assets, prevent and detect fraud and error, and secure as far as possible the completeness and accuracy of the records
a system for management to control certain risks and therefore help businesses achieve their objectives
2
Q

the board of directors
employees have some responsibility
3
Q
what are the elements of a sound system of internal control according to the Turnbull Report?
A
an internal control system encompasses the policies, processes, tasks, behaviours and other aspects of a company that, taken together:
- facilitate its effective and efficient operation by enabling it to respond appropriately to significant risks
- help ensure the quality of internal and external reporting
- help ensure compliance with applicable laws and regulations
the system of internal control will include:
- control activities
- information and communications processes
- processes for monitoring the continuing effectiveness of the system
the system of internal control should:
- be embedded within operations
- be able to respond to changing risks
- include procedures for reporting failings or weaknesses
4
Q
according to the Turnbull report, does a sound system of internal control eliminate human error?
A
no, reduces but cannot eliminate the possibility of poor judgement in decision making, human error
can be deliberately circumvented and occurrence of unforeseeable circumstances
reasonable but not absolute assurance

CONTROL ACTIVITIES = internal control
-after identification, actual specific control actives can be undertaken to reduce those risks
INFORMATION AND COMMUNICATION
-to operate the internal controls, they need quality information
MONITORING
- if system not monitored it will be very difficult to assess whether it is out of control and needs amendment

- the number of employees
- cost/benefit considerations
- changes in the organisational structures, reporting processes or underlying information systems
- changes in key risks could be internal or external in nature
- problems with existing internal control systems
- an increased number of unexplained or unacceptable events
55
how does the scale, diversity and complexity of the company's activities affect the need for internal audit?
larger, more diverse and the more complex a range of activities is, the more there is to monitor
56
how does the number of employees affect the need for internal audit?
as a proxy for size, no/ employees signifies that larger organisations are more likely to need internal audit to underpin investor confidence than smaller concerns
57
how does the cost/benefit considerations the need for internal audit?
must be sure benefits outweigh costs
58
how does the changes in the organisational structures, reporting processes or underlying information systems affect the need for internal audit?
any internal (or external) modification is capable of changing the complexity of operations and, accordingly, the risk
59
how does the changes in key risks could be internal or external in nature affect the need for internal audit?
the introduction of a new product, entering a new market, a change in any of the PESt/PESYEL factors or changes in the industry might trigger the need for internal audit
60
how does the problems with existing internal control systems affect the need for internal audit?
any problems with existing systems clearly signify the need for a tightening of systems and increased monitoring
61
how does the an increased number of unexplained or unacceptable events affect the need for internal audit?
system failures or similar events are a clear demonstration of internal control weakness

7) consider the loss of reputation if the fraud becomes public
85
what is a compliance audit?
- check the implementation of written rules, regulations and procedures
- used originally for financial transactions, because the government (tax authorities) needed assurance that the financial figures were correct

86
what is a transactions audit?
- involved checking of a sample of transactions against documentary evidence
- can be used where controls are weak or where transactions are high risk
87
what is a risk-based audit?
- a systems audit in which the auditors use their judgement to decide on the level of risk that exists in different areas of the system, and to plan their audit tests so that more effort is directed towards the most risky areas
- less time and effort is spent on elements of the system that are relatively 'safe'
88
what is a quality audit?
- systematic investigation to establish whether quality objectives are being met
- quality audit might look into the system for setting quality standards, the relevance of those standards, the system for comparing actual performance against the quality standards and whether the quality controls work effectively
89
what is a post-completion audit?
- independent appraisal of the measure of success of a project
- cover the project throughout its lifecycle from the planning and implementation stages through to performance after commissioning

93
what are the problems with VFM audits?
- difficult to measure outputs, esp for govt e.g. education

- spot risks
- investigate these
117
what are the different types of audit risk?
inherent risk
control risk
detection risk
118
what is inherent risk?
risk of the activity or operation, ignoring the controls in the system
related to both severity and the incidence of the risk
119
what does the size of an inherent risk depend on?
- size of the operations unit
- size of the expenditure budget
- the nature of the assets used or handles
- the extent to which procedures are computerised

- length of times since last audit: confidence diminished over time
122
how should auditors give priority in an audit plan?
priority for audit are those where the inherent risk is high and the quality of control is low
123
what is control risk?
risk that the existing controls are not sufficient to prevent or detect a material misstatement
124
what is a detection risk?
risk that the auditors' substantive tests will not reveal a materially incorrect amount in the financial statements, if such an error exists
125

- can see inefficiencies
systems documentation
- find documentation of the system
- best for computerised systems
- lease well understood by users
observation
-the operation of the system can be observed
127
how can auditors ascertain controls?
could use standard control questionnaires
- structures so as they identify all key internal controls
- enable the auditor to assess the quality of the controls
128
what might a flowchart be used to record?
- sequence of activities and checks within an operation or procedure
- which individuals carry out each procedure or check
129
what are the advantages to using a flow cahrt?

investigate causes of abnormalities
138
what is sampling?
testing a proportion to gain assurance about the population as a whole
139
what is audit sampling?
application of audit procedures to less than 100% of the items within an account balance or class of transactions to obtain and evaluate evidence about some characteristic of the items selected in order to forma conclusion on the population
140
what risks occur with sampling?
sampling risks: different to result if whole population tested
non-sampling risk:may use inappropriate methods or misinterpret evidence that the test results give so fail to recognise an error (avoidable)
141
why is the analytical review the most important type of test?
can be used on most items (financial or non financial) and at various points most important test as can be used on most items and at various points
-
can be used at planning ,substantive testing and overall review stages of an audit
142
```
what are some examples of the following types of ratios:
profitability
efficiency
liquidity
return
```
profitability: GPM, net profit
efficiency: receivables, inventory, payable days
liquidity: current ratio, quick ratio, gearing
return: ROCE, ROE
143
how can analytical reviews be used at the planning stage of an audit?
- identify risks
- help decide the level of testing
- decide nature and timing
144
how can analytical reviews be used at the overall review stage of an audit?
procedures are used to conclude whether the area being tested is consistent with the auditors' knowledge of the business entity and the expected results
145
when is it difficult to use analytical review method?
when there have been lots of one-off events in the year as there is nothing to compare them with
146
how is analytical review useful?
can help create an expectation if operations are significantly different from before and more so if the changes haven't been planned for
147
what features are common in the audit report?
objectives of the audit work
summary of the process undertaken by the auditor
results of tests carried out
audit opinion (should be cost effective and practical)
recommendations for action
148
what happens if the residual risk will not be reduced with the auditor reommendation?
the recommendation is not worthwhile
149
how is the recommendation commented on?
head of internal audit meets head of department
head will discuss points raised
can make their own arguments
150
how is the internal audit report circulated
after discussing with manager of department, submit report for review within internal audit and then send to audit committee
remains confidential within organisation
151
what audits are carried out on computer systems?
- check whether the system is achieving its intended objectives
- in the case of accounting systems, to check that the information produced by the system is reliable
152
what are the problems of auditing computer systems?
```
lack of primary records
encoded date
loss of audit trail
overwriting of data
program controls
concentration of controls in the IT department
```
153
why could concentration of controls in the IT department?
in large computer systems, many of the controls over data are concentrated int he central IT department
can be a potential weakness in the control system, if users are not aware of an accidental or deliberate corruption of data or programs
154
how could a lack of primary records be an issue when auditing computer systems?
document originating a transaction might not be creates
e.g. telephone order keyed in, call cant be traced
155
how could encoded data pose a problem to auditing computer systems?
risk of error in input details so effectiveness of program controls, such as data validation checks, to prevent the acceptance of incorrect data by the system, especially changes to standing data on a master file
156
how could loss of audit trail pose a problem to auditing computer systems?
should be evidence during processing of transaction in accounting system
in manual system, evidence provided by hard copy
computer systems minimise paper so no hard copy originals
157
how can overwriting of data be an issue for auditing computer systems?
when data are stored on a magnetic file, the file will eventually be overwritten with new data
if auditor needs some of the data to carry out tests, it will be necessary to take steps to make the data available
the auditor might therefore need to take copies of data files during the course of the year, and retain them for audit purposes
158
how can program controls be an issue for audit of computer systems?
the auditor has to test the controls in the computer system on which they intend to rely.
This means that testing the controls written into the computer programs
to do this, it will be necessary to use computer-assisted audit techniques
159
what are the characteristics of errors?
- no one-off errors unless deliberate amendment of individual items
- systematic errors which repeat across all transactions
- higher danger that input errors will not be detected
160
what are the 2 audit approach options for computer auditing?
- through the computer
| - round the computer
161
what is the round the computer approach?
the auditor does not attempt to understand the operation of the computer system, but rather treats it as a 'black box'
to audit the system, the auditor matches up inputs to predicted outputs to ensure that the outputs are being processed correctly
162
what are the advantages of the round the computer approach?
does not require high level of expertise of IT in the audit teams
163
when criteria have to be met for the round the computer approach to be suitable?
- computer processing is relatively simple
- audit trail is clearly visible
- substantial amount of up-to-date documentation exists about how the system works
164
what are the problems with auditing around the computer?
- computer files and programs are not tested, hence there is no direct evidence that program is working as documented
- errors are found it may be impossible to determine why they have happened
- all discrepancies between predicted and actual results must be fully resolved and documented no matter how small
165
what is the through the computer approach?
interrogates the computer files and computer controls and relies much more on the processes that the computer uses
auditor follows the audit trail through the internal computer operations and attempts to verify that the processing controls are functioning correctly
controls are directly tested and the accuracy of computer based processing of input data is verified
utilises different CAATs
166
what are the pros and cons of the computer approach?
requires more expertise and a longer set up time but of a very good quality
167
what is a CAAT?
computer-assisted audit techniques are methods of using a computer to carry out an audit of a computer system
168
what are the 2 main categories of CAAT?
audit software, such as audit interrogation software
| test data
169
what is audit software?
consists of computer programs used by auditors to interrogate the files of a client
normally the client's data files are input into the audit software program on the auditors' computer and the auditor can then test those files
170
what are some examples of what audit software can do?
- extract a sample according to specified criteria
- calculate ratios and select those outside the criteria
- check calculations
- prepare reports
- produce letters to send out to customers /suppliers
- follow items through a computerised system
- search for underlying relationships and check for fraud
171
what are audit packages generally designed to do?
- read computer files
- select information
- perform calculations
- create data files
- print reports in a format specified by the auditor
172
what are the pros and cons of an audit software
enables large volumes of data to be process very quickly and accurately
can take a long time to set up the systems with the client data and it will require expertise
173
how can CAAT help with fraud detection?
- comparing the home addresses of employees with the addresses of suppliers, to identify employees who are also suppliers
- searching for duplicate cheque numbers
- analysing the sequence of transactions to identify missing invoices or cheques
- identifying suppliers with more than one supplier code or mode than one mailing address
- finding several suppliers all with the same address
- listing payments for transactions that fall just within the spending authorisation limit of the individual who has authorised the payment
174
what are the benefits of CAATs?
- force auditor to rely on programmed controls during the audit, only way to test controls
- large number of items can be tested quickly and accurately
- test original documentation instead of print outs, therefore the authenticity of the document is more valid this way
- after initial set-up costs, using CAATs are likely to be cost-effective, as the same audit software can be used each year as long as the system doesn't change
- allow the results from using CAATs to be compared with 'traditional' testing
175
what are the weaknesses of CAATs?
- will be limited depending on how well the computer system is integrated. More integration, the better use of CAAT [ensure understanding of system to assess whether audit software is relevant]
- takes time to design CAATs tests therefore may not be cost-effective if the auditor is dealing with a bespoke system, as there may be a lot of set-up costs [CBA analysis of audit software]
- if the company you are auditing cannot confirm all system documentation is available, the the auditors will be unable to perform the tests effectively due to lack of understanding [do not use audit software until these have been identified]
- if there is a change in the accounting year, or from the previous year, then the audit software will have to be reset and designed, therefore may be costly[CBA from audit point of view should be carried out prior to deciding to use the audit software]
176
what is an embedded audit facility?
written into a program, particularly in on-line/real-time systems.
carry out automatic checks or provide information for subsequent audit
177
what type of audit checks/ information might an embedded audit facility provide?
- extracting and storing information for subsequent audit review, with sufficient details to give the auditor a proper audit trail
- identifying and recording items that are of some particular audit interest, as specified by the auditor
178
what is test data?
can be used by inputting the data into the system and checking whether it is processed correctly
expected results can be calculated in advance, and checked against the actual output from the system
auditors might include some invalid data in the tests, which the system should reject
179
when should test data be used?
only if the auditor is intending to do a 'test of controls' audit, and it must be considered cost effective
180
what is live dtata?
test data are processed during a normal production run
181
what is dead data?
test data are processed outside the normal cycle
182
what are the stages involved in using test data?
1) gain a thorough understanding of how the system being tested is supposed to work and controls that are included in it
2) devise the test data set. This should be a set of data containing both valid and invalid items. The controls in the system should identify the invalid items
3) Run the test data. This can be 'live' or 'dead'
4) evaluate the results. It is important that the auditor fully evaluates the results of the test data and does further work if unexpected results occur
183
Between live and dead data, which runs five more reliable results but are more risky to operate?
live data is more reliable but more risky
184
what are the risks with test data? what controls can be used to avoid this?
- damage to the system as the system is tested to its limits [ensure auditors understand the system and have software support]
- corruption of the systems data if test data are not properly removed [ensure process for data removal]
- system down time if 'dead' data used [establish when system can be used with minimum disruption to the business]
185
what are some examples of test data for revenue?
- input order that would exceed client limit:should pop up query asking if you wish to proceed
- input negative number of items on an order:should flag up negative number
- input incomplete customer details:system should not process order unless all information is completed
- inout an excessive amount:there are reasonable checks in the system to identify possible input errors
186
what are some examples of test data for purchases?
- raise an order from a supplier not on list:query should be raised about whether to proceed
- process an order with an unauthorised staff ID:system should reject the process altogether or send the request through to an appropriate person for authorisation
- try and make changes to the supplier standing data using the ID of someone who is not authorised to do so:system should reject the process altogether or send the request through to an appropriate person for authorisation
187
what are some examples of test data for payroll?
- try and set up a new employee up on the payroll system using an unauthorised ID:system should reject the process altogether or sent the request through to the appropriate person for authorisation
- try and make employee change of details sing an unauthorised ID: system should reject the process altogether or send the request through to an appropriate person for authorisation
- make an excess change e.g. salary change:system should have parameters in place to question this amount, and maybe reject it due to it being outside the normal range
