INTRODUCTION enacted the Sarbanes-Oxley Act 2002 in response

 INTRODUCTION1.

1. BACKGROUND OF STUDYMajorcorporate and financial collapses over the past decade have highlighted thevalue of internal audit (Pitt, 2014).According to (AbdulGaniyy, 2013), the collapse in the US of Enron andWorldCom together with their auditors, Aurthur Andersen, has focused the publicspotlight on the company audit and made it a highly controversial aspect of theaccountant’s work.

The US enacted the Sarbanes-Oxley Act 2002 in response tothe decline of public trust in accounting and financial reporting practices (Idigbe, 2007). In Nigeria, we alsoexperienced the AP Plc accounting scandal, Cadbury Nigeria Plc scandal in 2006etc. Suffice to say that the world as a whole has had cause to doubt theefficiency of the accounting and auditing profession. Thequestion of whether or not internal audit plays an important role has beengenerating lots of controversies over the years ( (Ugwu, 2014). The potentials forinternal audit to add value to organisations has been recognized as early as1948 according to (Pitt, 2014).  (Mutchler, 2003), further states that the particularrole and placement of an internal audit unit in an organization determines thedegree of reliance that should be placed on the assurance and consultingservices provided. Thisstudy aims to explore the possibility that the external auditor’s reliance onthe internal audit of a company is dependent on the independence of the boardand the effectiveness of the audit committee. According to the (Chartered Institute of Public Finance and Accountancy, 2006),the aim of the relationship between internal and external auditors is toprevent duplication of work.

International Standards on Accounting (ISA) 610further suggests that since the means of achieving the objectives of internaland external auditors are often similar there is an opportunity for asubstitution of effort between the internal and external auditors in order toavoid unnecessary duplication of work. Some regulatory system permits externalauditors to rely on the work of internal auditors in performing their financialstatement audit. According to Public Company Accounting Oversight Board (PCAOB)the internal auditing function must have met certain criteria before externalauditors would find efficiency in relying on the internal auditors’ work.

Research has shown that an internal audit system that reports directly to theaudit committee is considered reliable by external auditors. 1.2. STATEMENT OF RESEARCH PROBLEMSPriorliterature has focused on the effect of external auditing on the financialreporting of companies without exploring the effects the external auditors’reliance on internal auditing plays in external auditors’ effectiveness and howthe corporate governance of the organization affects the level of the externalauditor’s reliance on the internal audit function.

It is of general knowledgethat some recent corporate failures in Nigeria was as a result of weakcorporate governance (Deloitte, 2016). Until recently,research has failed to connect failures in internal audit reliance withinefficiency and independence of the board of directors.  It was however observed by (Gramling, Maletta, Schneider, & Church, 2004) that an internalaudit function that directly reports to the audit committee rather than to theorganisation’s management is seen as being more valuable and reliable from theexternal auditor’s perspective. It has however been observed that there are nostipulated or statutory rules guiding the effect that corporate governance hason internal audit reliability. It was observed by (krishnamoorthy & Maletta, 2016)  that the role of corporate governance oninternal audit reliance are issues not fully addressed in Federal regulations,auditing standards or stock exchange till date.  Otherproblems are: Other problems are:i.        The effects of board of directors’ lackof independence on the reliability internal audit functionii.

        The impact of board’s lack of integrityand objectivity in selecting the members of the audit committee.iii.        The effect of audit committee financialand technical inefficiency on the enterprise risk management techniqueiv.        External auditors’ inability to rely oninternal auditor’s work due to its lack of objectivity.v.
