Measurement of audit quality over the years has been treated thoroughly. The relationship between audit tenure and audit quality is treated in this research. The research instrument used in collecting data is the questionnaire, which is a primary method of data collection. The analytical instrument used is the Pearson’s correlation technique. The co-efficient observed are weak negative (-0.149), weak positive (0.026) and weak negative (-0.059) for the three research questions used in the study. The values are deemed to be non significant which hold that there is no significant relationship between the duration of auditor and the quality of financial reporting, there is no significant difference between audit objective and ability to maintain accountability by firms and that there is no significant relationship between audit rotation and fraud detection. The research recommends that short audit tenure should be discouraged and long audit tenure should be accepted which leads to higher financial reporting quality. The research also recommends the monitoring of audit firms by regulatory bodies to improve efficiency and transparency in financial reporting.

Background to the Study
In the past few years, auditors had been blamed due to their role in the mega corporate scandals such as Enron, WorldCom, Global crossing, Imclone system and Tyco international and in Nigeria such as Cadbury (Nig) Plc, African Petroleum (Nig) Plc. The criticism had raised lot of questions regarding auditors’ independence, such criticism leveled against auditors because they have be auditing their clients for a long time and subsequently concentrated more on non-audit services rather than audit.
The familiarity that exists between the auditors and their clients as a result of long audit tenure encourages failure in auditor independence. Though, there has been a call for sweeping changes in the auditing profession to ensure independence and therefore improved their audit quality (Palmrose, 2006).
The term audit is derived from the Latin word ‘audire’ which means to hear. In early days an auditor used to listen to the accounts read over by an accountant in order to check them. It was in use in all ancient countries such as Mesopotamia, Greece, Egypt, Rome, U.K and auditing (Ojo, 2009).
Auditing evolved and grew rapidly after the industrial revolution in the 18th century with the growth of the joint stock companies the ownership management became separate. The shareholders who were the owners needed a report from an independent expert on the accounts of the company managed by the board of director’s who were the employees. The purpose for this is to ascertain whether the account was true and fair rather than detection of errors and frauds (Petersen, 2005).
With increase in the size of companies and the volume of transaction the main objective of audit shifted to ascertaining whether the accounts were true and fair rather than true and correct. Hence, the emphasis was not on arithmetic accuracy but on a fair presentation of financial reporting (Lennox, 2005). Accounting and auditing play significant role in principal-agent relationship (i.e. agency relationship). The agency relationship between owners and manager in a firm creates a natural conflict of interest because of the information asymmetry that exists between managers and the owners. This information asymmetry means that manager generally has more information about “true” financial position (shown by statement of financial position), and results of operations (in a statement of comprehensive incomes) of the enterprise than the absentee owner does. This contract relationship between the shareholders and managers in a firm lead to the demand for firm auditing.
Auditing has a significant effect on firms, it helps to determine whether the overall financial statement present fairly in accordance with the established criteria, the extent to which rules, policies, laws audit and tracing funds or assets identification and recovery, investigating the existence, nature., extent and identification of employee who misappropriate asset.
Long term audit tenure has created some expectation gap this gap has led to failure of the auditor, to carryout is duty effectively. This is due, to the fact that the expectation of the auditors are not met because of the familiarity that exist between the auditors and their clients, this familiarity has made the auditors to fail in their area of independence, credibility and confidentiality because during long term audit tenure, auditors focus on non-audit service than audit services, and this led to many corporate scandal.
Statement of Problem
Several studies have attempted to evaluate possible explanatory variables for the state of audit quality. In the light of these studies, auditor tenure has become the focus of much debate. Should a firm replace its auditor’s on a regular basis, or should the auditor be allowed to build long-term relationship with the client? Studies on the effect of audit tenure on the quality of financial reporting are at polarity. A considerable number of these studies considered the rotation of audit firm as a way improving the quality of financial reporting. This is because familiarity with the client has the effect of reducing the fresh point of view auditors have in the early years of engagement. The Sarbanes-Oxley Act of 2002 consolidates this view as it requires rotation of the lead audit partner every five years so that the engagement can be viewed “with fresh and skeptical eyes”. The argument basically is that longer audit tenure trends to result in an opportunity cost of auditor independence, conversely, other studies also argue that longer auditor tenure improve auditor quality as auditor may need time to expertise in the business they audit and acquires client-specific knowledge overtime. This implies that audit quality is lower during the early year of the Auditor-client relationship, and the audit quality increases with length of the auditor-tenure due to the reduction in information asymmetry between auditor and client.
The research questions formulated from this research work are:
i. Is there any significant relationship between the duration of auditor and the quality of financial reporting?
ii. Does audit tenure improve the quality of financial reporting in achieving organizational objectives?
iii. Does audit objective help in maintaining accountability?

1.8 Limitations of the study
Some factors limit the extent and depth of this research work. These limitations include non-availability of adequate literature and the refusal of management to furnish some important documents/data for more detailed analysis on grounds of confidentiality.
Again, the unavailability of textbooks that deals on relevant areas of the study is another constraint. There were only few, textbooks to consult in the school library and most of them are obsolete. The researcher had to look outside the polytechnic library for relevant materials such as journals write-up etc.
Since the research work was done during the normal course of study, it was not possible to undertake an elaborate study.
