Chapter One of  Auditing Procedure and Internal Control System {a Case Study of Union Bank of Nigeria Plc}



An audit involves the independent examination of an expression person in accordance with the terms of engagement and the observance of statutory regulations and professional requirement (Okolie, 2008).  According to Milichamp (2003) the primary objective of an audit is to produce a report by the auditor of his opinion of the truth and fairness of financial statement, so that any person reading and using them can have belief in them.

Corporate management is a genetic term used to describe the way by which big and established companies with large networks are controlled of the purpose of achieving set goals.  Management is a universally acceptable and necessary concept irrespective of whether or not an organization exists to make profit.  It takes place at all levels in an organization and easy manager performs essentially the same function whether he belongs to top or middle or first line management.  The difference lies in magnitude of the task and the scope and degree of the authority.  American Institute of Certified Public Accountant, Chicago clearing House (1982) defined management as a process by which scarce resources are combined to achieve given objective.  It refers to the people that carry out the activities that are the manager.

Put different by Alter (1996), management may be described as the achievement of organization goals through people and after resources.  The Manager’s job is to combined and co-ordinate human, material and technical resources in the best way to achieve these goals.  Managers may not be directly involved in production; they produce to achieve the organization’s set goals.  Management indeed is a critical ingredient in the five MS.  Management, manpower, machinery, money and materials; which are the basic resources of any organization.

Corporate management has become complex in recent times.  The emphasis on decentralization, increasing use of delegation of authority and even in volume of trade has made the art of management so complex and intriguing that only managers who master the modern scientific method of management can cope with the increasing demands scientific method of management can cope with the increasing demand required by the poison.  To asses the complexity of the art of management, in the current increasing wake of business fraud, embezzlement and the cash squeezes which has crippled many companies because of the Structural Adjustment Programmes (SAP) and its attended foreign exchange and raw materials security.

In order to cope with the current situation and keep their business profitable, management has to look more inwardly, to increase the profitability of the company and to keep the overall activity of the company under control.  This can only be achieve through good effective internal control system of which internal auditing is a major problems and performance of every department in the company.

As representative of top management, the internal auditor is interested in determining whether each branch or department has a clear understanding of its assignment whether it is adequately stated, maintains good records, protects cash and inventories and other assets properly, co-operates with other departments and in general carries out effectively the functions provided for it in the overall plan and organization of the business.


The researcher is disturbed by various problems faced by an internal control system in an organization. Some of the problems include:

–              Suppression of information of middle management

–              Delegation of authority

–              Non compliance with laid down accounting procedure

–              Incomplete records

The study considered the needs for a system to ensure the physical assets of a proper management.

Above all, internal audit department should be created and charges with the responsibility for monitoring, evaluating and reviewing the system of internal control. This department, however, is faced with the problem of awareness and growth. It is only very few staff that know essence and usefulness of this. Department to the organization in which it operates. Some workers hold it behind them.

Failure to institute good control measures that act across the area of business would make it impossible for the company to detect immediately any abnormality. Fraud and errors committed in the course also encourage collusion of few staffs in perpetrating frauds and side tracking normal work procedure.

Effectively, internal audit improve employee skills, morale and knowledge while otherwise could resist in laziness and irresponsibility of staff. Also improper accounting information and reports could lead to poor financial position of an enterprise if there is no adequate financial data.

Since management can only be ensured through delegation of authority, it is only through a good internal audit system that the top management can determine the degree of compliance to delegation authority.

This system of appraisal and reviews needs to make sure that all delegation duties are being carried out effective and also that the policies and procedures of the company are being adhered to. Recession has led to the laying off of workers and this led to job combination. Too much workload by individual workers leads to various forms of errors and mistakes. It is the internal control that will check on errors of recording whether the errors were internal or not.

Finally, this study therefore investigate internal audit: An aid to management decision with a case study of Union Bank of Nigeria (UBN).


The primary purpose of this study is to:

–              To ensure efficient assets and liabilities management.

–              To under score the importance of internal control as a way of encouraging efficient performance through adherents to lay down organization procedure and accuracy of record.

The basic responsibilities of management are to safeguard assets, to be efficient in operation and also to produce reliable financial records. Management delegates some of these supervisors’ responsibility to the internal audit department and the major function of this department is to help management in performing its duties.

(i)           It helps the management of an organization to achieve some organization goals which include sound and adequate internal system and efficiency in other system of the organization among others.

(ii)         Management is responsible for the establishment of adequate accounting and internal control system.

(iii)       Internal control system is assigned specific responsibility for reviewing the design of the system, monitoring their operation and recommending improvement.

(iv)       It’ helps to identify the problems and prospect of internal system.


In the light of the problems under investigation, the flowering research questions were raised to facilitate empirical enquiry.

  1. Will internal control system give confidence to management on its activities?
  2. Does auditing procedure point out material errors and frauds?
  3. Does internal control system help management to keep proper control of its activities and responsibility?
  4. Will internal procedure make fraud and embezzlement less possible?
  5. Is internal system keeping records of transaction and safeguards assets and liabilities?


The research work will serve as an individual document for students, business executives, middle level management staff and other people. The result of the study will also be very essential to all government offices that are presently witnessing large-scale misappropriation of funds, fraud and poor accountability.

Although several studies have been conducted on internal audit as an aid to management decision, it is disappointing after a review of literature to report that very little has been achieved in checking fraud in most organizations.

This may be as a result of some of the earlier identified problems. Therefore, the present study serve as an eye opener to some of the top management authorities to correct all the identified problems areas.


In accordance with the research questions the following hypotheses were postulated and tested.

1.     H0:   Internal control system does not help management keep proper control of its activities and responsibilities.

H1:   Internal control system helps management keep proper control of its activities and responsibilities.

2.     H0:   Internal procedure does not make fraud and embezzlement less possible.

H1:   Internal procedure makes fraud and embezzlement less possible

3.     H0:   Internal control system does not give confidence to management on its activities.

H1:   Internal control system gives confidence to management on its activities.

4.     H0:   Internal system does not keep records of transactions and safeguard assets and liabilities.

H1:   Internal system keeps records of transactions and safeguard assets and liabilities

5.     Ho: Internal procedure does not point out material errors and frauds.

H1:   Internal procedure does not point out material errors and frauds.


This study only tries to point out the benefits of internal audit to management.

Internal audit is a component of internal control system; but as already stated this study is not going to review the internal control system in general, the study will not concern itself with procedure programmes and the general audit functions, since it does not intend to audit the organization. This scope of this study will not extend to the part of internal control system that involved internal audit.
