5. Internal auditing is an independent, objective
assurance and consulting activity designed to add
value and improve an organization’s operations.
It helps an organization accomplish its objectives by
bringing a systematic and disciplined approach to
evaluate and improve the effectiveness of the
organization’s risk management, control, and
governance processes.

25. Assurance Services
> 1 year
Formal consulting engagement
Independence and objectivity are strengthened by
Assigning different auditors
Independent management and supervision
Separate accountability for the projects
Disclosing the presumed impairment
25

26. Due Professional care
Expected of a reasonably prudent and competent
internal auditor, who should be alert to the possibility
of intentional wrongdoing, errors and omissions,
inefficiency, waste, ineffectiveness, and conflicts of
interest
Due care implies
Reasonable care and competence not infallibility or
extraordinary performance.
26

27. Oversight and responsibility for the IAA must not be
outsourced
Services must be performed in accordance with the
standards and the guidance for obtaining external
service providers should be considered (PA 1210).
27

28. CAE should assess the competency, independence and
objectivity of the outside service provider.
When the outside service provider performs Internal
Auditing activities the CAE should specify and ensure
that the work complies with the SPPIA.
28

29. Quality Assurance and Improvement
Program covers all aspects of the IAA and continuously
monitors its effectiveness.
Should help the IAA add value and improve the
organization’s operations and provide assurance that
the IAA is in conformity with the Standards and Code
of Ethics.
29

30. Ongoing Reviews

and threats that affect the achievements of objectives
54

55. CAE should obtain an understanding of management’s
and board’s expectations of the internal audit activity in
the organization’s risk management process.
55

56. Objectives support and align with the mission.
Significant risks are identified and assessed.
Appropriate risk responses are selected that align
risks with the organization´s risk appetite
Relevant risk information is captured and
communicated in a timely manner across the
organization, enabling staff, management and board
to carry out their responsibilties.
56

57. Formal ↔ informal
Quantitative ↔ subjective
Business unit ↔ at corporate level
57

58. Internal auditors can facilitate or enable risk
management processes, but they should not “own” or
be responsible for the management of the risks
identified.

deterrence of fraud by examining and evaluating the
adequacy and the effectiveness of control,
commensurate with the extent of the potential
exposure/risk in the various segments of the entity’s
operations.
64

65. Responsibilities of the internal auditor
Have sufficient knowledge of fraud to be able to
identify indicators

organization if there are sufficient indicators to
recommend an investigation.

89. 89
Discrete variables
1. Uniform distribution: All outcomes are equally likely
(coins).
2. Binomial distribution: Only 2 possible outcomes (quality
control)
Formula: n! x pr(1-p)n-r
r!(n-r)!

90. 90
3. Bernoulli distribution: only 1 trial ↔ binomial as many as
necessary.
4. Hypergeometric distribution: = binomial sampling without
replacement.
5. Poisson distribution: event may happen more than once with
random frequency during a given period.
Formula: f(k) = λke-λ λ = mean and variance
k! k = number of
occurences

91. 91
Continuous variables
1. Normal distribution

92. 92
Distance in standard
Deviations
Area under the curve
<confidence coefficient> <confidence level>
1.0 68%
1.64 90%
1.96 95%
2.57 99%

93. 93
Regardless of the distribution of the population from
which random samples are drawn, the shape of the
sampling distribution of the mean approaches the
normal distribution as the sample size is increased.

94. 94
Probability of zero occurences in a time period T.
For the exponential distribution, M is used instead
of λ → P = e –m (k=0)

95. 95
3. T-distribution
Small samples, less than 30 with unknown variance.
4. Chi-square distribution: comparison of sample variance
and population variance. Is the sample likely to be from the
population.

96. 96
1. Judgment (non statistical sampling)
2. Statistical sampling
Test of controls
(attribute sampling)
Substantive testing
(variables sampling)
Sampling risk: probability that a properly
drawn sample may not represent the
population.

4. PPS = DUS

101. Amounts
Modified version of attribute sampling, relates error rates to
amounts.
Sampling unit
Dollar, Pound, Euro etc.
Stratification
Because the larger account balances have a greater chance of
being selected.
101

102. 102
Overstatements
It is good to test for overstatements, not effective for
estimating understatement errors. Testing of account balances:
inventory, receivables, loans.
Few errors
Useful if few errors are expected
As the number of expected misstatements increases, MUS
requires a larger sample size than classical variables sampling.

103. 103
1. Define audit objectives
2. Define population:
- Noting distributional or systematic patterns
- What type of items included
- Time period
- Population size
3. Determine sampling method
4. Determine the desired precision
= maximum acceptable error rate

104. 104
5. Determine the desired reliability
= confidence level
6. Calculate the sample size
7. Judge the significance of the discovered errors
Conclusions about the population

105. 105
Precision = interval estimator =
confidence interval = prediction interval

106. 106
Incorporates sample mean, population standard deviation
+ probability that the interval includes the true population
parameter
For the population mean this interval is
x ± z (6:√n)
Standard error of the mean

107. 107
Type I error = α
Type II error = β

108. 108
Statistical
Non statistical

109. 109
The end result of sampling
More than just the numbers
Affected by various factors
- Nature of system of control
- Views on administration.
- Views on training and experience of people
- Effect of erroneous transactions
- Effect on other transactions

110. 110
Use scientific sampling when they best fit the audit
objectives
Base audit opinions only on the population sampled
Let every item have an equal chance of being selected
Do not let personal bias affect the sample
Do not permit population patterns affect the
randomness of the sample

111. 111
Do not draw conclusions about the entire population
from a directed sample
Base estimates of maximum error rates on what is
reasonable
Stratify wherever it would appear to reduce
variability in the sample
Do not set needlessly high confidence and precision
levels
Do not stop with statistical results, know why the
variances occurred.
