Internal Controls - Learn About the Auditor's Role in Control Activities                                         



1.1 Background of the Study

Globalization and the advancement in technology has become the hallmark for businesses today and the banking sector is no exception. Banks have been expanding their operations and activities beyond the domestic borders as a result of globalization and improved technology. The expansion of business, globalization and the advanced technology also exposes business to increased risk, fraud, altercations and other irregularities. This has made internal controls an imperative system to maintain by every business and for that matter the banking sector. Globalization of businesses, technological advancements, increasing risk of business failures, the fraud and altercations that emerged in the financial sector in Nigeria call for the proper maintenance of an effective internal control systems through.

Internal audit is to help an organization accomplish its objectives by bringing systematic disciplined approach to evaluate and improve the effectiveness of risk management control and governance processes. Internal check are duties whereby checks are imposed on all aspects of work so that no person is solely responsible for all parts the account procedure. Segregation of duty as a single control activity and the key to good internal control system and procedure design, that no single person should be responsible to recording and processing of a complete transaction in other to reduces the risk of intentional manipulation or accidental error. Whatever the decision taken in an organization internal control processes, effective and efficient measure with an appropriate manner of approach. These internal control tools are refers to a system within an organization which prescribe the decision of authority, responsibility of activities and their direction and recording for the purpose of creating a smooth operating procedure in an efficient and progressive manner, so ordered that a degree of check and restraint exist, resulting in the achievement of the organization’s purpose within a minimum of waste and a maximum of production or gain (GUPTA 2005).

It has been discovered that due to lack of internal control several banks have been     discovered to have defrauded its customers mostly foreign investors, Having discovered this, banks now take extra precaution before clearing a cheque because of rampant incidence of fraud and forgeries which have placed bank. Loss on average of Nlm each working day of the year in Nigeria. Due to this challenges, CBN issued a directive to banks to increase its capital base to N25 billion. Management use internal control as a tool to check it staff due to the fact that managers are not able to monitor the activities of the organization. It therefore adopts the internal control in such a way that the system checks itself and any irregularity within the system is been detected and corrected.

To ensure that the system checks itself, management could use devices such as segregations, supervision of work and acknowledgement of performance. The effective arrangement and implementation of this control system would ensure proper management.

Internal controls are to be an integral part of any organization’s financial and business policies and procedures. Internal controls consist of all the measures taken by the organization for the purpose of:

  1. Protecting its resources against waste, fraud, and inefficiency;
  2. Ensuring accuracy and reliability in accounting and operating data:
  3. Securing compliance with the policies of the organization; and
  4. Evaluating the level of performance in all organizational units of the organization. Internal controls are simply good business practices. (Kansas State University – USA June 30, 2003)

For some time now, risk management in general and internal control more specifically; have been considered as fundamental elements of organizational governance. As a consequence, risk management is beginning to be perceived as a new means of strategic business management, linking business strategy to daily risks and then optimizing those risks in order to realize value (Saarens and de Beelde 2006)

The Idea of internal control system becomes very important in an organization due to its vital role for example, the internal auditors of an organization are also part of the internal control system consist of both the internal auditors and the management team. So, it is the duty of every one to ensure conformity in the day -to-day activities of the organization also the need for profit maximization in an organization cannot be under estimated if the organization must remain in business this view bring about the idea of operational efficiency which can only be achieved through proper checks and balances within the organization.

The concept of internal control system covers all financial units, business activities including among other things:

  1. Mechanism of internal check in an organization.
  2. Financials cost and management accounting control functions.
  3. Internal audit.

1.2 Statement of Problem

There have been incessant cases and stories been told about high frequency of fraud, embezzlement, overcharging, manipulation, missing files and ledger cards and other banking malpractices in banks today, with the management and shareholders not knowing how to handle the adverse situation. Despite the fact that internal control system have been in existence for many years in most organisation, the problem of financial crimes, have continued to be on the increase. Examples of this financial crimes include; financial irregularities within the departments, collusion among senior or highly-trusted employees, breaches of control, to mention a few. Various researchers, have affirmed that internal control set by management in most organisation has not been able to completely prevent these fraudulent occurrences because these controls have not significantly reduced the reoccurring fraud and corruption perpetuated by employees in most organizations. More so, with the proliferation of banks and also the increase in rural banking, with commercial bank’s branches, the volume of accounting records has drastically increased, thereby necessitating the appraisal of the adequacy and reliability of records, and overall efficiency of operations. Furthermore, with the public interest in the “truth and fairness” of financial statements – profit and loss account and balance sheet, whose stratum of reliable is on the internal control system, the research is therefore aimed at investigating the extent of adherence to the internal control system and its impact on the profit performance of the banks.

1.5 Significance of the Study

The research is intended to define the level of impact of internal control system on the financial performance of deposit money bank in Nigeria. It findings will be of great importance to the banking staffs especially the managers and officers whose interest are geared towards the enhancement of the chances of bank profitability; in serving as a guide in the performance of their duties. It will assess the effect of fraud, manipulations, errors, improper authorization, dishonesty, inadequate accounting records etc on profitability in view of the existing internal control system. A comprehensive knowledge of system of internal control will form a foundation on which the auditor’s report on “true and fair view” final account is based and as such, the study will be of immense values to the practicing Accountants, Auditors, Lawyers, shareholder and other interested parties for acceptance and reliance of financial statement. Furthermore, it will include more research in the improvement of banking services in Nigeria for the interest of the shareholders, customers and government. Finally, the study will provide the basis for recommendation to the management of the best approach to designing, installing and operating an improved system of internal control aimed at promoting operational efficiency and eliminating or at least minimizing waste.

1.6 Scope and limitations of study

This study covered the internal control systems adopted by various commercial banks in Nigeria. The population sample was taken from only five banks along with their branches in Lagos State. Other parts of the country were not covered, though empirically generalized view was made of them.

The study was restricted to two major areas of internal centre. They are:

  1. Administrative control
  2. Accounting and financial control (internal checks, internal audition and other financial system of control). This was done based on a comprehensive understanding of the principles of good internal control.

However, the study encountered a lot of constraints as regards time, money and sourcing of information. Effort geared towards obtaining adequate information proved abortive due to the uncooperative attitude of some interviewed staff. Besides, no bank likes the public to know the deficiencies in its internal control as the confidence reposed on it by the public might be lost. But, irrespective of these limitations, an in-depth study was still carried out. Another limitation of this study is that the study was focused on 5 banks only while we have others deposit money banks, therefore these findings may not be used for generalizations on all banks in Nigeria. It is therefore important for a study to be conducted using wider scope and coverage then, the findings can be compared and conclusions drawn.
