The Effect of Auditor Independence on Corporate Financial Scandals in Deposit Money Banks in Nigeria (A Study of First Bank, Access Bank and Guaranty Trust Bank Plc in Lagos State)

CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Auditing plays a vital role in maintaining public confidence in financial reporting. Since its inception, one of the key objectives of the audit profession has been to strengthen trust in financial statements. Auditors are expected to provide an independent and objective opinion on the preparation and presentation of such statements. To achieve this, they must act independently and base their conclusions on evidence rather than influence or bias (Farouk & Hassan, 2014).

Financial statements are essential tools for decision-making. They offer stakeholders insight into an organization’s financial health and performance (Dogan, Coskun, & Celik, 2017). According to Farouk and Hassan (2014), financial statement audits help reduce information asymmetry between management and stakeholders by ensuring that the information presented is accurate and credible. Consequently, audit quality directly affects the level of trust users place in financial reports.

In developing economies like Nigeria, auditor independence is even more critical due to weaker governance structures and higher corruption risks (Kitata, 2016). When auditors lose their independence, financial statements can become unreliable, which in turn undermines investor confidence and economic stability. Financial scandals such as those involving Cadbury Nigeria and EcoBank in the early 2000s highlighted how weak internal controls and compromised audits could damage the integrity of financial systems (Ferguson, 2008).

The Nigerian financial sector has witnessed several corporate failures, especially during the 1990s and 2000s, which raised questions about the credibility of auditors. Studies by Okike (2004), Bakre (2007), and Ajibolade (2008) show that many corporate collapses resulted from auditors failing to detect or report fraud and irregularities. ThisDay (2009) also reported that unethical practices among bank executives revealed lapses in the ethical standards of auditors, bringing the profession under public scrutiny. As a result, the independence of auditors has become a matter of national concern (Bhasin, 2013).

Auditor independence ensures that the auditor’s opinion is objective and free from influence. It forms the foundation of public confidence in audit reports. When independence is compromised, users lose trust in financial statements. A credible auditor must therefore act without bias and avoid situations that could impair objectivity (Gray & Ratzinger, 2012). However, as Mr. Jim Henry, a chartered accountant, noted, auditors often face challenges when management restricts access to information. Such limitations can prevent them from uncovering material misstatements or fraudulent activities.

In Nigeria, questions about auditor independence became more prominent after the 2008 global financial crisis, which exposed serious weaknesses in corporate governance. Many financial institutions failed due to poor risk management and weak auditing practices. The Securities and Exchange Commission (SEC, 2000) later emphasized the importance of maintaining independence to ensure credible reporting. Consequently, this study investigates the effect of auditor independence on corporate financial scandals in deposit money banks in Nigeria.

1.2 Statement of the Problem

Auditing is a systematic process that involves objectively evaluating financial statements to determine whether they present a true and fair view of an organization’s financial position (American Accounting Association, 1973). Auditors are expected to perform their duties with diligence, integrity, and independence. However, in recent years, concerns about the independence of auditors have increased following numerous financial scandals across Nigeria’s banking industry (Shafie, Hussin, Yusof, & Hussain, 2014).

Ideally, auditor independence should reduce the occurrence of corporate financial scandals. Unfortunately, many Nigerian banks continue to experience cases of fraud, fund misappropriation, and unethical reporting. These cases raise questions about whether auditors are executing their duties with the required objectivity and transparency (Abu Bakar, Abdul Rahman, & Abdul Rashid, 2014).

Research also suggests that factors such as long audit firm tenure, lack of rotation, and the provision of non-audit services can compromise audit quality (Kaplan & Mauldin, 2008). Despite regulatory interventions, financial scandals persist. This situation has reduced public confidence in financial reporting and eroded the credibility of the accounting profession. Carey and Simnett (2006) found that prolonged auditor tenure could lead to audit failure due to overfamiliarity between auditors and management.

Many of the existing studies were conducted in foreign contexts with limited relevance to Nigeria’s financial environment. For example, Abu Bakar et al. (2014) conducted a study using a small sample size and focused mainly on loan officers’ perceptions. Similarly, Carey and Simnett (2006) studied the Australian market, which differs significantly from Nigeria’s financial system. Therefore, there is a research gap concerning the effect of auditor independence on financial scandals in Nigerian deposit money banks. This study aims to fill that gap.

1.3 Research Questions

This study seeks to answer the following questions:

1. To what extent does auditor independence affect financial scandals in Nigerian deposit money banks?

2. What is the relationship between audit firm rotation and financial scandals in Nigerian deposit money banks?

3. How does the quality of audit reports influence financial scandals in Nigerian deposit money banks?

4. What is the effect of audit firm tenure on financial scandals in Nigerian deposit money banks?

1.4 Objectives of the Study

The main objective of this research is to examine the effect of auditor independence on corporate financial scandals in deposit money banks in Nigeria. The specific objectives are to:

1. Determine whether audit firm rotation influences financial scandals in Nigerian banks.

2. Assess how the quality of audit reports affects financial scandals.

3. Evaluate the extent to which audit firm tenure influences financial scandals in Nigerian banks.

1.5 Research Hypotheses

The following null hypotheses were formulated:

H₀₁: Auditor independence does not significantly affect financial scandals in Nigerian deposit money banks.
H₀₂: There is no significant relationship between audit firm rotation and financial scandals in Nigerian deposit money banks.
H₀₃: Audit report quality does not significantly affect financial scandals in Nigerian deposit money banks.
H₀₄: There is no significant relationship between audit firm tenure and financial scandals in Nigerian deposit money banks.

1.6 Significance of the Study

This study contributes to both academic research and professional auditing practice. Theoretically, it enhances the understanding of factors that threaten auditor independence, such as self-interest, self-review, advocacy, and familiarity threats. It also provides insight into how independence affects financial reporting and corporate integrity.

Practically, the study offers valuable guidance to auditors, policymakers, and financial regulators. It emphasizes the need for effective governance mechanisms to strengthen audit quality and prevent scandals. Students and researchers in accounting and finance will also benefit from the findings as a reference for further research. Moreover, policymakers may use the results to enhance auditing standards and improve financial oversight.

1.7 Scope and Limitations of the Study

The study focuses on auditor independence as it relates to financial scandals in Nigeria’s deposit money banks. It examines three banks located in Lagos State: First Bank, Access Bank, and Guaranty Trust Bank. Primary data were collected using questionnaires administered to staff members of these banks.

Some limitations affected the research process. First, distance posed a challenge, as data collection required travel to Lagos. Second, some bank staff were uncooperative, delaying responses and reducing the sample size. Despite these challenges, efforts were made to ensure accuracy and reliability in the findings.
