Auditing
of the Internal Control System
Internal control system (ICS) can be defined as the
combination of the organizational structure management and the efforts, methods,
procedures adopted and permanently realized by the management of the company.
The aforementioned activities are aimed at the following goals and objectives:
·
improvement of the company’s activity and its management structures;
·
provision of the financial-economic activity effectiveness;
·
safety of the company’s assets;
·
internal and external risks’ prevention;
·
assurance of the reports and statements of the company;
·
observance of the legislation and internal documentation requirements as
well as the regulations accepted within the company.
Reliable ICS is the key element of the company’s
corporate governance system and it allows the company’s management to reach
adequate decision with respect to the improvement of the company’s business
processes; identification, prevention and restriction of the operational,
financial and other types of risks in
active and effective way; provision of the reasonable confidence in achieving
strategic goals of the company and its shareholders.
Formation of the reliable ICS, which is able to
increase business effectiveness and protect shareholders’ interests, is the
responsibility of the company’s management. However, even the “well-built” and
organized ICS needs to be evaluated from the standpoints of effectiveness and
economy. The role of independent and
professional appraiser evaluating the reliability and effectiveness of existing
ICS should be fulfilled by the internal audit, which evaluates the ICS and
thereafter suggests recommendations for its improvement (optimization).
One of the core audit procedures directed to achievement
of adequate conclusions in relation to reliability and effectiveness of ICS operation
is testing the actual risk management procedures taking into account the risks
peculiar to the business process being analyzed.
When performing the test for ICS reliability the
auditor aims at identifying probability of achieving the goal set towards the control
procedure, which in turn allows the owner of the analyzed risk to effectively
manage the given risk. In this respect the control procedure goal is defined by
the auditor based on the analysis of the process, interview with the owner of
the process or independently with reference to the “best practices” of
organizing the given processes in similar companies.
Generally, testing is performed by the auditor on a sample
basis. The sample size should provide enough grounds for the auditor to be
confident in the fact that the conclusions made on the basis of sample data
analysis would be applicable for the whole size of data (in the aggregate)
being sampled and tested. Moreover, the sample size could be defined either with
an application of special formulas derived from probability theory and
mathematical statistics or based on professional judgment of the auditor.
Referring to the testing results the auditor should
give an assessment for the existing ICS in terms of managing the risk being
analyzed. The evaluation should also indicate the possible scenarios of the
given risk realization (taking into account the extrapolation of the sample
test results for the whole aggregate). If required the auditor would formulate
the recommendations regarding arrangement and optimization of the existing ICS for
the business process purposes.
ICS assessment should be performed taking into
consideration the fee for the control procedure alone as well as the cost
required for the creation and support of the whole ICS. Recommendations
concerning the existing ICS arrangement and optimization should be reasonable
from the “cost-benefit” analysis standpoint. In case several control procedures
are operating with a purpose of managing one risk or related (dependent) risks
it is required to make an assessment for different scenarios of using control
procedures so that extra (duplicating)
procedures are excluded.
The analysis of control procedure effectiveness is
performed with respect to provision of reasonable assurance for achievement of
the analyzed business process’s corresponding goals.
Effectiveness and adequacy of internal control system
should be defined bearing in mind not only the specific forms, methods of
control, quantity of people involved in control, number of conducted
inspections and identified errors (mistakes) but also management and the
company owners’ activity (or failure), which is directed to incorporation of
internal control in all business processes, prompt risk assessment, and effectiveness
of control procedures used for mitigation of risk effects. In this regard
detection of disadvantages or violations could be considered as an alarm
signaling potential problem related with an absence or wrong operation of
control system; and this requires thorough analysis of the reasons and good
understanding of business process.
The joint work of internal audit with the management
of the company in terms of building and optimization of ICS is mainly directed
to control over the program of correcting actions, which were considered as
necessary in view of the audit findings.
Another direction of the aforementioned collaboration
is related with provision of consulting support for the management. Top
management of the company is responsible for creation of reliable ICS and
maintenance of the system’s proper operation. However management of the company
usually needs for additional specific knowledge and skills in the areas such as
internal control and risk management. Thereby internal audit could be attracted
as a consultant on the issues relating to testing of the introduced internal
control procedures, assessment of control methods, examination of the internal
control procedures’ fulfillment as well as a provider of methodological support
during organization of internal control processes and risk management.
