DOCUMENTING
THE INTERNAL CONTROL SYSTEM
Benefits
of Internal Control to the
entity
Based
on our previous studies we can
now identify the following
principal benefits that may
arise for an
entity
from a sound system of
internal control:
a)
Assurance
that all transactions are
completely and accurately
processed.
b)
Confidence
that only authorized transactions
takes place.
c)
Assurance
that adequate documentation supporting
transactions is created and
retained.
d)
Assurance
that the company's assets
and liabilities are correctly
stated, in order for them
to
make
informed decisions on the operations of the
business.
e)
Minimization
of the risk of fraud and misappropriation
of assets.
Benefits
of Internal Control to the
auditor
Of
course, if the audit client benefits
from a sound system of
internal control, it is likely
that the auditor will
also
be benefited. All of the above stated
benefits help to promote a situation
where the financial
statements
present
a true and fair view. In
simple terms, a good system
of internal control will
make life easier for
the
auditor.
Auditor's
work on the Internal
Control
International
standards on auditing emphasize the
importance of internal control to the
auditor by stating
that
auditor should:
a)
Obtain
an understanding of the accounting and
internal control system
sufficient to plan the
audit
and develop an effective audit approach,
and
b)
Use
professional judgment to assess the
components of audit risk and to
design audit
procedures
to ensure it is reduced to an acceptably
low level.
At an
early stage in their work
auditors will have to decide the extent
to which they wish to place
reliance on
the
internal controls of the enterprise. As the
audit proceeds, that
decision will be kept under review
and,
depending on the
results of their examination, they may
decide to place more or less
reliance on these
controls.
Categories
of Internal Control
These
are often summarized by
using the mnemonic SOAP MAPS as
follows:
a)
Supervision
b)
Organization
c)
Arithmetic and
Accounting
d)
Physical
e)
Management and
Monitoring
f)
Authorization
g)
Personnel
h)
Segregation of duties
a)
Supervision
There should be
adequate supervision of work to ensure
that controls are being complied
with.
Possible
application: a supervisor or manager
reviews and checks the work
of a subordinate.
b)
Organization
Enterprises
should have a formal, documented
organization structure with clear
lines of
responsibility.
Possible
application: lines of authority within an
organization make it clear which
individuals are
responsible
for
decisions and
transactions
c)
Arithmetic and Accounting
The
company should ensure that
there are adequate controls to
ensure the completeness
and
accuracy
of its financial records.
58
Fundamentals
of Auditing ACC 311
VU
Possible
application: standard accounting
procedures such as the use of
control accounts,
reconciliation
procedures
and the performance of arithmetic checks
on accounting records.
d)
Physical
There should be
adequate physical control to
ensure the security and
safekeeping of its assets
such
as
plant and machinery,
valuable inventory items and
cash.
Possible
application: banking cash immediately,
controlling access to inventory
areas; electronic tagging of
inventory
and portable non-current
assets.
e)
Management and Monitoring
There should be
sufficient controls in existence to
ensure management can
effectively control the
business
operations.
Possible
application: the use of budgeting and
standard costing systems; the
establishment of an internal
audit
department
f)
Authorization
All
transactions should be authorized.
Possible
application: authorization of purchases,
cash and bank payments, sale
of non-current assets,
sales
to
customers on credit, bad debt
write offs.
g)
Personnel
Employees
should be appropriately qualified and of
suitable caliber to perform the required
tasks.
Possible
application: recruiting the right people
for the job; training them effectively,
motivating and
rewarding
employees in an appropriate way.
h)
Segregation of duties
There should be an
appropriate division of responsibilities to reduce the
opportunity for fraud
and
manipulation.
This
is a fundamental control procedure
designed to ensure that one
person does not have
sole
charge
of a transaction from beginning
till end. Perfect
segregation of duties exists
where each of
the
main stages in a transaction
are under the control of a different
person.
Possible
application:
Consider
an inventory purchasing system in a
manufacturing company:

Documenting
the system
Documenting
the system is an extremely important
stage in the audit;
Auditing
standards state that in
planning the audit, auditors should obtain
and document
an
understanding
of the
accounting system and
control environment sufficient
to determine their audit
approach.
The
various methods of ascertaining
and recording the system may be
summarized as follows:
1. Organization
chart
2.
Narrative notes
3
Flowcharts
4
Internal control questionnaires
(ICQs)
5
Internal control evaluation
checklists (ICEC)

Narrative
Notes
This is a
simple and apparently convenient way of
describing systems. Having
ascertained the system, the
auditor
draws up a narrative description of it for the
audit files. An example
might be:
Sales
invoices are prepared by
Mr._____ They are checked by
Mr. _____ and then
passed to Mr. _____
for
recording in the
customer's account in the sales
ledger etc.
Shortcomings
of the method:
1.
Notes can take up a
disproportionate amount of space
2.
Notes may be difficult to
interpret
3.
What happens it personnel
change?
Flowcharts
This
is becoming an increasingly widely used
technique for recording accounting
systems in audit
files.
A
flowchart is a diagrammatical
representation of an accounting
system.
A good
flowchart will be supplemented
with narrative.
Flowcharts
have the following
advantages:
(i)
They
portray the flow of documents
through the system and
enable the auditor to relate
those
movements
with procedures and checks
carried out as part of that
system.
(ii)
They
show the movement of documents in such a
way that, when properly
prepared, the
sources
and destinations of all
documents will be
clear.
(iii)
They
help to highlight weaknesses in the
control of the business.
(iv)
They
enable audit tests to be
clearly related to weaknesses in the
accounting system.
Standard
symbols are used to
represent documents, operations and
checks carried out.
Flow
lines are used to join up
the symbols and represent the movement of
documents.
Dotted
lines are used to represent
the flow of information between
documents.
Essentials
of flowchart
Internal
control evaluation flowcharts must
highlight
the following:
(a)
the sequence of
operations happening to
each document (e.g. authorization,
checking, matching,
filing)
(b) the
segregation
of staff duties and
who is responsible for each
operation.

Flowchart of
purchases
Narratives:
1 Requisition
note raised when
goods
are at a
pre-set re-order level. Order
quantity is
pre-determined by use of a
copy of
the previous purchase order.
2 Signed by
store manager.
3 Buyer
checks authorization.
4 Purchase order
set prepared.
8 P02 filed
temporarily to act as a
check
on overdue
deliveries.
10 P04 and
P05 are filed until goods
are
received.
11 Weekly
check on overdue deliveries.
12 Goods
checked to PO to ensure
they
are in
agreement.
13 If not
damaged, goods are
accepted
and a goods received
note set is raised.
Where
quantity received is below order a
shortage
memo set is also raised and
a
note made
on the purchase order.
14 P05 is
sent back to the warehouse
to
act as the
next requisition
note.
Commentary
on the above flowchart
(a)
All operations and checks
are positioned on vertical lines
within a particular department.
(b)
Horizontal lines show the movement of a
document between departments.
(c) In
practice the flowchart would continue,
dealing with the processing of the
purchase invoice/credit
note/day
books/payables ledger/cash book etc.
The
flow-lines
at the bottom of the page would continue
to page 2 of the flowchart.
(d)
Note that the narrative to the flowchart
does not deal with
all of the operation numbers
since some
should be
self-explanatory e.g. operation 9
represents the
numerical
filing of P03 in the buying
department.
