Lesson 36
VERIFICATION OF BANK
BALANCES
Following points should
be considered during verification of Bank Balances:
i) Agree the balances
with the bankbook, and/or general ledger and bank statement.
ii) In case of
difference between bank book and bank statement obtain reconciliation for the
bank
accounts.
iii) Check that
outstanding cheques have been cleared with the bank statement subsequent to
the
year-end. If cheques
have not been cleared subsequently ask for any special reason why they have
not been cleared.
iv) Check that
uncollected cheques have been realized, with the statement for subsequent
period.
v) Scrutinize the
subsequent bank statement for dishonored cheques in order to detect
worthless
cheques deposited to
conceal shortages.
vi) Investigate any
significant reconciling items of an unusual nature.
vii) Investigate about
outstanding stale cheques.
viii) Obtain direct bank
confirmation.

Verification of Debtors
Balances
Following points should
be considered during verification of Debtors Balance:
i) Obtain confirmation
from debtors.
ii) Verify debts with
reference to cash received since year-end.
iii) Check accuracy and
completeness of debtors' listing.
iv) Check book-keeping
in small sample of ledger accounts.
v) Check postings and
enquire into unusual entries in the control account.
vi) Verify nature,
amount and classification of credit balance.
vii) Check transaction
of foreign currency balances.
viii) Review post
year-end credit notes.
ix) Enquire into debtor
balances cleared by journal entries after the year-end
x) Consider un-provided
claims, enquire and review correspondence.
xi) Check credit note
cut-off, if material.
xii) Consider adequacy
and check bases and calculations of provisions for rebates
xiii) Verify existence
and title to bills receivable, trace proceeds.
xiv) Consider whether
results of work on cutoff affect debtors.
xv) Review audit work on
income.
Confirmation from
Debtors:
Through verification of
debtor’s balances by direct communication the auditor obtains information
regarding:
(i) Adequacy of the
system of internal control over sales, debtors, and collections;
(ii) Accuracy of
accounting records in general and of cut-off procedures for balance sheet
purposes
in particular; and
(iii) Irregularities
such as teeming and lading, overdue balances & incorrect balances.
The above information
helps an auditor to form an opinion regarding:
(a) Reliability of
debtors balances; and
(b) Quantum and nature
of disputes existing between the company and its customer.
Methods of obtaining
Debtors Confirmation
(i) Positive Method.
Under positive method the company requests the debtor to confirm his
indebtedness to the
company direct to the auditor and in case of disagreement he is also required
to
state the balance as per
his records and provide the auditor with full particulars of the
difference.
(ii) Negative Method.
Under negative method the company requests the debtor to communicate with
the auditor only if he
disagrees with the balance. If no communication is received within specified
time the auditor may
assume that the balance is agreed.
Distinguish between
Positive and Negative Confirmation
Positive
Confirmation Negative Confirmation
a) In positive
confirmation company request, the debtor
to confirm the balance
direct to the auditor whether he
agrees while or not.
b) In positive
confirmation if no reply is received the
auditors have to adopt
other procedures to verify those
balances.
c) Positive confirmation
is preferred when the internal
control system is not
satisfactory.
d) Confirming
significant balances due from debtors under
positive
confirmation.
In negative confirmation
company request, the
debtor to confirm the
balance to auditor only
if he disagree with
balance.
In negative confirmation
if no reply is received
the auditor may assume
that the balance is
agreed.
Negative confirmation is
preferred when the
internal control system
is satisfactory or when
confirming a large
number of small balances.
Confirming a large
number of small balances
under negative
confirmation.
118
Other procedures if
reply is not received to Positive Confirmation
When no reply is
received to a positive confirmation the auditor should carry out the following
procedures:
i) Check the outstanding
balances as of balance sheet date have been subsequently received.
ii) If subsequently not
received then examine sale order, dispatch note, invoices and relevant
documents and
correspondence with concerned debtors.
119

last year.
iii) Verify that the
depreciation calculations for additions and disposals during the year are in
accordance with the
accounting policy.
iv) Analytical
Review
120
Check that
depreciation for the year is reasonable in relation to book value, stated
policies
and previous
years.
d. Staff Loans
i) Examine the services
rules and regulation of the company, note major particulars regarding
staff loan.
ii) Examine and evaluate
internal control. Authority in particular important.

vi) Obtain certificate
direct from staff.
vii) If loan is secured,
examine the security.
viii) See that adequate
provision for amount of doubtful recovery is made in the accounts.

Lesson 38
AUDIT SAMPLING
Meaning and objective:
Audit sampling means
application of audit procedures to less than 100 % of items appearing in an
account balance or class
of transactions to enable the auditor to form conclusion concerning that
population.
Why Sampling?
Audit sampling enables
an auditor to gather audit evidence through the use of tests of control or
substantive procedures,
on selected number of items and forming conclusion about the whole
population. The reasons
for this are:
a. Economic: Audit
becomes cost effective.
b. Time: Complete check
would take so long time.
c. Practical: Users do
not expect 100% accuracy. Materially is important in accounting as well as
in
auditing.
d. Psychological: A
complete check would be boring for the audit staff.
e. Fruitfulness: A
complete check would not add much to the worth of figures if few errors
were
discovered. The emphasis
in auditing should be on the completeness of record and the true and
fair view.
Exceptions to Sampling
In some cases a 100%
check is still necessary. Some of these are:
a. Categories which are
few in number but of great importance e.g., land and buildings.
b. Categories with
special importance where materiality does not apply e.g., directors' emoluments
and loans.
c. Unusual, one-off, or
exceptional items e.g., accidental loss.
d. Any area where the
auditor is put upon enquiry e.g., legal matters, law suits.
e. High risk
areas.
Approaches to Audit
Sampling:
There are two approaches
to sampling in auditing:
a. Judgmental sampling
b. Statistical sampling
We will deal with each
in turn.
Note that the objective
in all sampling is to draw conclusions about a large group of data, e.g., all
the
credit sales made in a
period, or all the withholding tax calculations or all the debtors, from an
examination of a sample
taken from the group.
Objectives of Audit
Sampling:
Auditor is supposed to
carry out procedures designed to obtain sufficient appropriate audit evidence
in order to determine
with reasonable assurance whether the financial statements are free of
material
misstatements.
Here the words
“reasonable and material” make it clear that it is not necessary that auditors
should state
that the financial
statements are absolutely 100% accurate. Sampling does not provide absolute
proof
of 100% accuracy but it
can provide reasonable assurance that some elements of the financial
statement are free from
material misstatement.
Audit sampling
means; drawing
conclusions about an entire set of data by testing a representative
sample of items.
Population
means; the set of
data, which may be a set of account balances (e.g. debtors, creditors,
fixed assets) or
transactions (e.g. all wage payments, all advice notes).
Sampling units
means; the
individual items making up the population.
Audit Materiality and
Risk
Audit materiality
(Tolerable error)
An auditor is not
required to have evidence that all items in a set of Accounts are 100% correct.
His
duty is to give an
opinion on the truth and fairness of the Financial Statements. Errors can exist
in the
Accounts and yet the
Accounts can still give a true and fair view.
122
The maximum error that
any particular magnitude can contain without marring (damaging) the true
and fair view is the
tolerable error. Tolerable error is auditing materiality
In his audit planning,
the auditor needs to determine the amount of tolerable error in any given
population and to carry
out tests to provide evidence that the actual errors in the population are less
than the tolerable error.
For example, stock can be a large amount in a set of accounts. Stock is
computed by counting and
weighing, by multiplying quantity by price and by summing individual
values. Errors can occur
at any of these stages. Applied prices may be incorrect. The effect of
incorrect prices may be
to compute a stock figure that is above or below the correct stock figure by
an amount that is above
the tolerable error.
Audit Risk
This term applies to the
risk that the auditor will draw an invalid conclusion from his audit
procedures. Audit risk
has several components:
i)
Inherent risk: This is
the risk attached to any particular population because of factors like:
• The type of industry -
a new manufacturing hi-tech industry is more prone to errors of all
sorts than a stable
business like beverage.
• Previous experience
indicates that significant errors have occurred.
• Some populations are
always prone to error, e.g. stock calculations, work in
progress.
ii)
Control risk: This
is the risk that internal controls will not detect and prevent material
errors. If this risk is
large the auditor may avoid compliance tests altogether and apply only
substantive tests.
iii)
Detection risk: This is
the risk that the auditor's substantive procedures and analytical
review will not detect
material errors.
The assurance that an
auditor seeks from sampling procedures is related to the audit risk that he
perceives.
The sample sizes
required will be related to materiality and to audit risk.
To sample or not?
The auditor, in considering
a particular population, has to consider how to obtain assurance about it.
Sampling may be the
solution. Factors which may be taken into account in considering whether or
not to sample include:
a. Materiality: Petty
cash expenditure may be so small that no conceivable error may affect the
true
and fair view of the
accounts as a whole?
b. The number of items
in the population: If these are few (e.g. land and buildings), a 100%
check may be economic.
c. Reliability of other
forms of evidence: Analytical review (e.g. wages relate closely to number
of
employees, budgets,
previous years, etc.) Proof in total (GST calculations). If other evidence is
very strong, then a
detailed check of a population (100% or a sample) may be unnecessary.
d. Cost and time
considerations can be relevant in choosing between evidence seeking methods.
e. A combination of
evidence seeking methods is often the optimal solution.
Stages of Audit
Sampling
a. Planning the
sample.
Audit objectives. Why is
this test being carried out? What contribution does it make to the
overall assessment of
true and fair view?
The population. The
population has to be defined precisely. This may be all sales rather
than all sales invoices.
(Can you see the difference?)
The sampling unit. Note
that in compliance testing it is the operation of the control on a
transaction not the
transaction which is the sampling unit.
The definition of error
in substantive tests. In stock calculations, an error of greater than
Rs.100 only may
constitute an error for this purpose.
The definition of
deviation in compliance tests. The deviation may be any failure to carry
out a control procedure
or it may be a partial failure.
The assurance required.
This is a function of the other sources of evidence available,
123
The tolerable
error or deviation rate. This is related to materiality.
The expected
error/deviation rate. This is a factor which is not intuitively expected
by
students. In fact,
errors increase the impreciseness of conclusions drawn from sampling and
larger sample sizes are
required if there are many errors.
Stratification. It may
be desirable to stratify the population into sub-populations and sample
them separately or in
some cases, such as high value items, do a 100% check.
b. Selection of the
items to be tested.
c. Testing the items.
d. Evaluating the
results. This should also be done in stages:
Analyze the
errors/deviations detected in relation to the planning definitions.
Use the
errors/deviations detected to estimate the total error in the population. This
is called
projection of the errors
from the sample to the population.
Assess the risk of
an incorrect solution. This will be related to the amount of projection
of
error compared with the
tolerable error and the availability of alternative evidence
Judgmental Sampling
This means selecting a
sample of appropriate size on the basis of the auditor's judgment of what is
desirable.
This approach has some
advantages:
a. The approach has been
used for many years. It is well understood and refined by experience,
b. The auditor can bring
his judgment and expertise into play. Some auditors seem to have a sixth
sense.
c. No special knowledge
of statistics is required.
d. No time is spent on
playing with mathematics. All the audit time is spent on auditing.
There are some
disadvantages:
a. It is unscientific.
b. It is wasteful -
usually sample sizes are too large.
c. No quantitative
results are obtained.
d. Personal bias in the
selection of samples is unavoidable.
e. There is no real
logic to the selection of the sample or its size.
f. The sample selection
can be imbalanced to the auditors needs e.g. selection of items near the
year
end to help with cut-off
evaluation.
g. The conclusion
reached on the evidence from samples is usually vague - a feeling of it seems
OK
or of vague worry.
Overall, judgmental
sampling is still the preferred method by a majority of auditors. Partly this
can be
defended on the grounds
that the auditor is weighing several strands of evidence (internal control,
business background,
conversations with employees, subjective feelings, past experience, etc.) and
is
usually investigating
several things at once (e.g. more than one control evidenced on an invoice,
proper books, internal
control compliance and substantive testing of totals) so that the whole
process
is too complex to reduce
to the simple formulations of the statistician. On the other hand, the
statistician can reply
that judgment sampling in the past worked well because very large samples were
always taken. Today, the
small samples required by economic logic require careful measuring of the
risks attached and this
can only be done by the use of statistical techniques.
124
Lesson 39
STATISTICAL SAMPLING
Drawing inferences about
a large volume of data by an examination of a sample is a highly developed
part of the discipline
of statistics. It seems only common sense for the auditor to draw upon this
body
of knowledge in his own
work. In practice, a high level of mathematical competence is required if
valid conclusions are to
be drawn from sample evidence. However most firms that use statistical
sampling have drawn
complex plans which can be operated by staff without statistical training.
These
involve the use of
tables, graphs or computer methods.
The advantages of using
statistical sampling are:
a. It is scientific.
b. It is defensible /
justifiable.
c. It provides precise
mathematical statements about probabilities of being correct.
d. It is efficient -
overlarge sample sizes are not taken.
e. It tends to cause
uniform standards among different audit firms.
f. It can be used by
lower grade staff; that would be unable to apply the judgment needed by
judgmental sampling.
There are some
disadvantages:
a. As a technique it is
not always fully understood so that false conclusions may be drawn from
the
results.
b. Time is spent playing
with mathematics which might better be spent on auditing
c. Audit judgment takes
second place to precise mathematics.
d. It is inflexible.
e. Often several attributes
of transactions or documents are tested at the same tir Statistics does
not
easily incorporate this.
Characteristics of audit
sample:
In auditing, a sample
should be:
a. Random - a random
sample is one where each item of the population has an equal (or
specified)
chance of being
selected. Statistical inferences may not be valid unless the sample is random.
b. Representative - the
sample should be representative of the differing items in the whole
population. For example,
it should contain a similar proportion of high and low value items to
the population (e.g. all
the debtors).
c. Protective -
protective, that is, of the auditor. More intensive auditing should occur on
high value
items known to be high
risk.
d. Unpredictable -
client should not be able to know or guess which items will be examined.
Sample Selection
Methods:
There are several
methods available to an auditor for selecting items. These include:
a. Haphazard -Simply
choosing items subjectively but avoiding bias. Bias might come in by
tendency to favor items
in a particular location or in an accessible file or conversely in picking
items because they
appear unusual. This method is acceptable for non-statistical sampling but is
insufficiently accurate
for statistical sampling.
b. Simple random - All
items in the population have (or are given) a number. Numbers are
selected by a means
which gives every number an equal chance of being selected. This is done
using random number
tables or computer or calculator generated random numbers.
c. Stratified - This
means dividing the population into sub populations (strata = layers) and is
useful when parts of the
population have higher than normal risk (e.g. high value items, overseas
debtors). Frequently
high value items form a small part of the population and are 100% checked
and the remainders are
sampled.
d. Cluster sampling -
This is useful when data is maintained in clusters (= groups or bunches)
as
wage records are kept in
weeks or sales invoices in months. The idea is to select a cluster
randomly and then to
examine all the items in the cluster chosen. The problem with this method
is that this sample may
not be representative.
125
e. Random systematic -
This method involves making a random start and then taking every nth
item thereafter. This is
a commonly use method which saves the work of computing random
numbers. However the
sample may not be representative as the population may have some serial
properties.
f. Multi stage sampling
- This method is appropriate when data is stored in two or more levels.
For example stock in a
retail chain of shops. The first stage is to randomly select a sample of
shops and the second
stage is to randomly select stock items from the chosen shops.
g. Block sampling -
simply choosing at random one block of items e.g. all June invoices. This
common sampling method
has none of the desired characteristics and is not recommended.
h. Value weighted
selection - This method uses the currency unit value rather than the items as
the sampling population.
It is now very popular and it is also known as “Monetary Unit
Sampling”. This in
relatively new variant of discovery sampling which is thought to have wide
application in auditing.
This is because:
a. Its application is
appropriate with large variance populations. Large variance populations
are those like debtors
or stocks where the members of the populations are of widely
different sizes.
b. The method is suited
to populations where errors are not expected.
c. It implicitly takes
into account the auditor’s concept of materiality.
Procedures are:
a. Determine sample
size. This will cover:
i. The size of the
population
ii. The minimum
unacceptable error rate (materiality)
iii. The Beta risk
desired
b. List the items in the
population (e.g. 1,250 debtors)

Etc.
*** ***
Etc.

*** ***
_______ _______
300,000 300,000
====== ======
c. If the sample size
were 100 items then take a random start say 1,000 and every 3,000th (Rs.
300,000/100 sample size)
item thereafter, i.e. using systematic sampling with a random start.
The idea is that:
i. The population of
debtors is not the 1,250 number of debtors but Rs. 300,000.
ii. If the particular
Rupee is chosen then the whole balance of which that Re. 1 is a
part will be
investigated and any error quantified.
In our example, Razi
would be selected since 1,000 lies in his balance and then Saif would also be
chosen as 1,000 + 3000 =
4,000 lies in his balance.
Note that the larger
balances have a greater chance of being selected. This is protective for the
auditor
but it has been pointed
out that balances that contain errors of understatement will have reduced
chance of
detection.
d. At the end of the
process, evaluate the result which might be a conclusion that the auditor is
95% confident that the
debtors are not overstated by more than Rs. ***. Where Rs. *** is the
materiality factor
(tolerable error) chosen. If the conclusion is that the auditor finds that
the
debtors appear to be
overstated by more than Rs. *** then he may take a larger sample
and/or investigate the
debtors more fully.
Monetary unit sampling
is especially useful in testing for overstatement where significant
understatements are not
expected. Examples of applications include debtors, fixed assets
126
and stocks. It is
clearly not suitable for testing creditors where understatement is the primary
characteristic to be
tested.

Lesson 40
CONSIDERING THE WORK OF
INTERNAL AUDITING
Introduction (Meaning of
Internal Audit)
Internal audit is part
of internal control, set by the management, delegating its supervisory
functions
to specially assigned
staff, with the objective to see that the internal controls are in operation
and to
assist them in
fulfilling their responsibilities such as
1. safeguarding of the
assets
2. reliability of
financial records and
3. efficiency in
operation
Definition
“Internal auditing”
means an appraisal activity established within an entity as a service to the
entity.
Its functions include,
amongst other things, examining, evaluating and monitoring the adequacy and
effectiveness of the
accounting and internal control system.
DIFFERENCE BETWEEN
INTERNAL AND EXTERNAL AUDITORS
INTERNAL AUDITOR
EXTERNAL AUDITOR
Objective:
Accounting system and internal
control are operating
efficiently.
Report on Financial
statements.
Responsibility
Responsibility to the management. Responsibility to the share
holders.
Scope of work Determined
by management.
Determined by the
statute; otherwise
determined through
mutual agreement
between auditor and the
client.
Scope and Objectives of
the Internal Audit Function
Although the exact
nature of internal audit function is determined by the management, however,
generally the aims and
objectives of the internal audit function are:
i) Review and assessment
of the internal control procedures and accounting system.
ii) Examination of
financial and operating information for management, including detailed
testing of transactions
and balances.
iii) Review of
efficiency, economy and effectiveness of operation.
iv) Review of compliance
with laws, regulations, management policy and other internal
requirements.

Requirements Vs Independent Report on Financial Statements
Unlike the internal
auditor who is an employee of the enterprise, the external auditor is required
to be
independent of the
enterprise, usually having a statutory responsibility to report on the
financial
statements giving an
account of management’s stewardship.
Common Means
Some of the means
adopted by both the auditors to achieve their respective objectives are common,
e.g. evaluation of
internal control. Therefore, certain aspect of internal auditing may be useful
in
determining the nature,
timing and extent of external audit procedures.
Dependence Vs
Independence
Whatever be the degree
of autonomy given by the management to internal auditing it cannot enjoy
the same degree of
independence as external auditors. Moreover, the responsibility for the report
is
that of the external
auditor alone, and therefore is indivisible and is not reduced by the reliance
on
internal auditing.
128
As a result, all final
judgments relating to matters which are material to the financial statements or
other aspects on, which
he is reporting, must be made by the external auditor himself.
Understanding of
Internal Auditing
The external auditors
should obtain a sufficient understanding of internal audit activities to assist
in
planning the audit and
developing an effective audit approach.
Effective internal
auditing will often allow a reduction in the procedures performed by the
external
auditors but cannot
eliminate them entirely. However, external auditor may decide not to use the
internal auditor’s work.
Preliminary Assessment
of Internal Auditing
After obtaining
understanding of internal auditing, if it appears that its work is relevant for
external
auditors, the external
auditor should, during the course of planning perform preliminary assessment
of internal auditing
function. An effective internal audit may allow a modification in the nature,
timing
and extent of procedures
performed by external auditors.
Criteria while Obtaining
Understanding and Preliminary Assessment of Internal Auditing
Before relying on the
work performed by the internal auditor, it is necessary for the external
auditor
to make an assessment of
the effectiveness and relevance of the internal audit function by considering
the following:
i)
Organizational status:
The internal auditor is an employee of the entity and therefore
cannot be independent,
however the external auditor should evaluate to what extent he is
free in performing his
duties and communicate with external auditor and consider any
constraints placed upon
his work.
Ideally, internal
auditor should be reporting to the highest level of management and should
be free from other
operating responsibility.
ii)
Scope and Objectives of
Internal Audit Function: The external auditor should examine
the range and aim of the
assignments assigned to internal auditors by the management and
whether management acts
on internal audit recommendations.
iii)
Technical Competence:
The external auditor should ascertain whether staff of the internal
audit function has
adequate technical training and proficiency as auditors.
iv)
Due Professional
Care: The external auditor should consider whether the internal auditor
has performed his work
with reasonable care and skill i.e. work is properly planned,
supervised and reviewed.
He should also consider existence of working papers, work
programs, audit manuals
etc.
Liaison and Coordination
The extent of liaison
would normally encompass the following:
i) Initial planning to
formulate a joint approach to minimize the tests performed by the two
auditors i.e. tests
level, sample selection, documentation of work performed, review and
reporting
procedures.
ii) Regular meetings
between the internal and external auditors during the year.
iii) Exchange of
knowledge between the two auditors i.e. the external auditors should be
informed of any
significant matter that comes to the knowledge of internal auditor which
he believes may affect
to work of external auditor. Similarly the external auditor should
inform the internal
auditor of any significant matters which may affect his work.
Evaluating Internal
Audit Work/Review/Controlling
Where the external
auditor has decided to place reliance on the work of internal auditor, he
should
review the working
papers to satisfy himself as to:-
i) Audit programs are
adequate.
ii) The work is
performed by trained staff and the work of assistants is properly
supervised, reviewed and
documented.
iii) Sufficient
appropriate audit evidence was obtained.
iv) Conclusions made are
appropriate.
v) Reports prepared are
based on the work done.
129
vi) Exceptions or
unusual items have been properly resolved. The external auditor
should record all the working
he has received. The external auditor should also
test the work of
internal auditor.
Testing the Work of
Internal Auditing
It can be done in
the following ways:
i) Re-performing the
work done by internal auditor, on test basis, to ensure that the same
results are
achieved;
ii) Selecting a few
similar items and perform independent test; and
iii) Observation of
internal auditing procedures.
