To achieve the key financial objective of the firm, that is, profit maximization, the
two pre-requisites are efficient utilization of resources and margins management.
“The two main pre-requisites for profit maximization are efficient utilization of
resources and margins management; hence, profit is maximized when resources are
efficiently utilized and margins are well managed. (Ayodeji, 2011: 107). The efficient
utilization of resources argument is the economists‟ viewpoint to profit maximization
while margins management is the accountants‟ viewpoint to profit maximization.
Efficient resource utilization can otherwise be called economic efficiency. It can be
sub-grouped into productive and allocative efficiency. Achievement of productive
efficiency requires operational and production control, as productive efficiency
requires quality control leading to efficient materials or stock control, labour or
personnel control whereas, allocative efficiency on the other hand, requires efficient
personnel planning and control, recruitment policy and quality control.
Margins management another aspect has two elements; Cost or expense minimization
and revenue maximization. Cost minimization is anchored on cost control and cost
reduction strategies. Hence, margins management requires cost control.
From all the foregoing, it is evident that achievement of economic efficiency and
margins management will be a mirage if effective control strategies are not put in
place, whether financial or non-financial. As a result of this, in the internal operations
and workings of an entity, there is the need to put proper systems of control in right
perspectives, such internally entrenched controls are termed internal controls.
Internal control, the strength of every organization, has become of paramount
importance today in our Organizations. The reason being that the control systems in
any organization is a pillar for an efficient accounting system. The need for the
internal control systems in an organization cannot be undermined, due to the fact that
the economy, which has a crucial role to play in the economic development of a
country, is now being characterized by economic instability, slow growth in real
economic activities, corruption and the risk of fraud. Fraud, which is the major reason
for setting up an internal control system, has become a great pain in the neck of many
Nigerian organizations. (Olaoye Clement Olatunji 2009)
For organizations to be able to function effectively and contribute meaningfully to the
development of a country, the industry must be safe, stable and sound. And for these
conditions to be obtained there must be a sound accounting system, which is
occasioned by an internal control system.
A system of strong internal controls can help to ensure that the goals and objectives of
a banking organization will be met, that the bank will achieve long-term profitability
targets and maintain reliable financial and managerial reporting.(Etuk Ifiok Charles
These days, many people are talking about how to control financial security. One
strategy is to improve the internal control system that was first put forward in the
United States. The current representative outline, the COSO report (Internal controlIntegrated Framework), has reached maturity, and the basic framework for internal
control systems has already been formed. The report concluded that internal control
systems have the following features: (1) effectiveness and efficiency of operations;
(2) completeness and accuracy of records (3) adherence to management policies (4)
safeguard the assets of the organization. For organizations, an internal control system
is a necessity. Without it, they will have difficulty achieving profitability or normal
operations. (Sato Takahiro; Pan Jia 2012).
Internal controls, however, are the whole systems of control, financial or otherwise,
established by the management to carry out the business of the enterprise in an
orderly and efficient manner, ensure adherence to management policies, safeguard the
assets and secure as far as possible the completeness and accuracy of records.
Profitability is the profit earning capacity which is a crucial factor contributing to the
survival of the firms. The perpetual existence of the firms depends on the profit
earning capacity of the firm, which is also considered to be the main factor in
influencing the reputation of the firm. Therefore, it is necessary to differentiate profit
and profitability at this juncture.
Profit, from the accounting point of view, is arrived at by deducting from the total
revenue of an organization all amount expended in earning that income whereas
profitability can be measured in terms of profit shown as a percentage of sales known
as profit margin (T.Venkatesan ; Dr S.K. Nagarajan 2012).
1.2 Statement of the Problem
Establishment of an Internal Control System has been seen as a key aspect of
controlling a business organization as an important management tool of co-ordination
for achieving business profitability. It has been defined by the Operational Standard
(of Auditing Guidelines) as “the 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 and secure as far as possible the completeness and accuracy of the records”.
By this, the objectives or purposes of internal control system can be obtained from the
definition. These are:
I. To ensure that the business is carried out in an orderly and efficient manner
II. To ensure adherence to management policies.
III. To safeguard the assets of the organization.
IV. To secure the completeness and accuracy of records.
All these objectives are believed to be instrumental to the achievement of the
profitability objective of a business firm, as each one should engender either cost
minimization or revenue maximization or even both, the two being the two aspects of
profitability maximization objective.
However, with the entrenchment of internal control system in most organizations,
some of them still find it difficult to achieve the financial objective of profitability;
hence, it appears that internal control system does not have any positive bearing on
corporate profitability. As a result of this, the research problem lies on the fact that, it
is doubtful whether:
I. economic efficiency can engender cost minimization and revenue
II. adherence to management policies actually fosters cost minimization and
revenue maximization.
III. safeguard of corporate assets specifically enhances profitability
IV. completeness and accuracy of records can be instrumental to corporate
1.3 Research Objectives
Bearing in mind the significance of internal control system in the achievement of
corporate financial objectives, and the research problem in specifics, there is the need
to carry out a research of this nature with the objective of considering, evaluating,
assessing, studying and examining the impact of internal control system on the
corporate profitability. Therefore, the specific objectives of this study are to:
I. assess the level of influence economic efficiency has on revenue
II. consider the extent to which adherence to management policies can foster
revenue maximization.
III. examine the extent to which safeguard of corporate assets can engender cost
IV. examine the degree of impact completeness and accuracy of records have on
cost minimization.
1.4 Research Questions
As a direct consequence of the fact that the research is both quantitative and
qualitative, the following questions were asked to which answers were supplied to
find dependable solutions to the research objectives:
I. Does economic efficiency have any influence on revenue maximization?
II. To what extent can adherence to management policies engender revenue
III. Do safeguard of assets have any positive bearing on cost minimization?
IV. Do completeness and accuracy of records have any impact on cost

1.6 Significance of the Study
Due to the current situation of the organizations generally, there is the need to search
for alternative strategies, policies, guidelines and solutions to the poor performances
of organization.
However, students and researchers of high working experiences would benefit from
this study, as the conceptual framework and theoretical framework of this research
would enhance their knowledge and understanding of the subject matter.
Also, the members of the organization including the management, stakeholders and
directors would find this work a useful guide in minimizing their cost and maximizing
their revenue.
This study would as well be helpful to the regulatory authorities of Internal control
system. This is in order for them to evolve better policies in achieving the soundness
and the stability of Internal Control and ensuring adherence to management policies.
Therefore, the significance of this research work is a bi-faceted one, which is to
identify areas of possible improvements and find solutions to the listed problems on
one hand and to contribute to the body of knowledge.
1.7 Scope of the Study
This research focuses on Impact of Internal control system on cost minimization and
revenue maximization as the two aspects of profitability. The scope of the issues that
were examined is limited to the overall objectives of the research. The causes, effects
and solutions to any irregularities discovered are widely addressed. However, the
spatial dimension covers the corporate entities in Nigeria.
1.8 Limitations of the Study
Here we identify the various challenges and constraints that were faced by the
researcher from attaining the scope of the study to the fullest.
Some of these constraints include:
1. Materials: All relevant information needed for this study was not provided due
to the fact that there were restricted access to materials needed for this study.
Some corporate entities are reluctant to releasing some information about the
financial statement of their organization.
2. Finance: Lack of sufficient funds to execute the research project could also be
seen as a challenge of the researcher. As a result there were restriction and
limits that the researcher could go because sufficient finance is needed to
execute the project fully.
3. Information adequacy: Unavailability of Information required for effective
research may be a limitation of the study. Facts were not easy to come by as a
result of the fact that some of the information were outdated or not related to
the study.
