PROBLEMS AND PROSPECTS OF AUDITING IN GOVERNMENT ORGANIZATION (A CASE STUDY OF FEDERAL MORTGAGE BANK)

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Auditing is a systematic and independent examination of books, accounts, statutory records, documents, and vouchers of an organization to ascertain how far the financial statements present a true and fair view of the concern. Auditing also seeks to ensure that the financial transactions of an organization comply with relevant laws, regulations, and internal policies. In government organizations, auditing serves an even more critical function than in private sector entities. Public sector auditing focuses on accountability, transparency, and the proper use of public funds. Government auditors examine whether public resources are used economically, efficiently, and effectively (the “three E’s” of public auditing: economy, efficiency, and effectiveness). The ultimate purpose of government auditing is to provide assurance to citizens, legislators, and other stakeholders that public funds are managed responsibly (Premchand, 2019; Mellett, 2019).

The Federal Mortgage Bank of Nigeria (FMBN) is a prominent government organization established to provide affordable housing finance to Nigerians. The bank was originally established as the Nigerian Building Society (NBS) in 1956, transformed into the Federal Mortgage Bank of Nigeria in 1977, and later re-established under the FMBN Act of 1993. FMBN is the apex mortgage institution in Nigeria, charged with the responsibility of mobilizing funds for housing development, providing mortgage credit facilities to Nigerians, promoting the development of the mortgage finance industry, and administering the National Housing Fund (NHF). The bank is wholly owned by the Federal Government of Nigeria, the Central Bank of Nigeria (CBN), and other financial institutions. As a government organization handling billions of Naira in public funds, FMBN is subject to rigorous auditing requirements (FMBN, 2023; Adebayo and Oyedokun, 2019).

Auditing in government organizations like FMBN differs significantly from auditing in private sector entities. In the private sector, the primary objective of an audit is to express an opinion on whether financial statements present a true and fair view (fairness audit). In the government sector, audit objectives are broader, encompassing regularity audit (compliance with laws, regulations, and budget approvals), performance audit (value for money, efficiency, and effectiveness), and financial audit (accuracy of financial statements). Government auditors are also required to report on internal controls, compliance with statutory provisions, and instances of waste, fraud, or mismanagement. The audit report is submitted not only to management but also to oversight bodies such as the Office of the Auditor-General of the Federation, the National Assembly Public Accounts Committee, and in the case of FMBN, the Federal Ministry of Power, Works and Housing and the Central Bank of Nigeria (Chan, 2018; Okafor and Udeh, 2020).

The Office of the Auditor-General of the Federation (OAuGF) is the supreme audit institution of Nigeria, responsible for auditing all government organizations, including FMBN. The Auditor-General is appointed by the President on the recommendation of the Federal Executive Council and confirmed by the Senate. The office conducts audits annually and submits reports to the National Assembly, which reviews them through its Public Accounts Committees. The Constitution of the Federal Republic of Nigeria (1999, as amended) and the Audit Act provide the legal framework for public sector auditing. In addition, the International Standards of Supreme Audit Institutions (ISSAI) issued by the International Organization of Supreme Audit Institutions (INTOSAI) guide best practices in government auditing. FMBN is therefore subject to multiple layers of audit oversight (OAuGF, 2020; Ogbeifun, 2019).

Despite the existence of legal and regulatory frameworks, auditing in government organizations in Nigeria faces numerous problems and challenges. These include: inadequate funding for audit offices, which limits the scope and depth of audits; lack of qualified and experienced audit staff, particularly those with specialized skills in performance auditing and information technology; political interference and pressure on auditors to suppress adverse findings; late submission of accounts by government organizations, which delays audits and reduces their timeliness and relevance; weak enforcement of audit recommendations, with many Public Accounts Committee reports not acted upon; lack of independence of internal audit units within government organizations; and the complexity of auditing government programs that involve multiple layers of government and implementing partners. For FMBN, these problems may limit the effectiveness of audits and the value derived from the audit process (Eze and Nwafor, 2020; Oyo-Ita, 2019).

One of the most significant problems affecting auditing in government organizations is the lack of adequate funding for audit institutions. The Office of the Auditor-General of the Federation has historically been underfunded, despite its constitutional mandate. This underfunding limits the number of audit staff that can be hired, the training they can receive, the technology they can deploy, and the number of audit assignments they can complete. Inadequate funding also affects the independence of auditors, as they may become reliant on the very organizations they audit for resources. For FMBN, which has complex operations involving mortgage lending, property management, and financial intermediation, underfunding of the audit function could mean that high-risk areas are not adequately examined (Adebayo and Oyedokun, 2020; Nwankwo and Okeke, 2021).

Another critical problem is the shortage of qualified audit staff, particularly those with specialized skills. Government auditing in a financial institution like FMBN requires knowledge of banking, mortgage finance, property valuation, and information systems, in addition to traditional accounting and auditing skills. However, public sector salaries are often not competitive with private sector or international organizations, making it difficult to attract and retain top talent. Many experienced auditors leave public service for better-paying positions, leaving a gap in institutional knowledge and expertise. The lack of continuous professional development and training opportunities further compounds this problem. For FMBN, the quality of its audit (both internal and external) depends heavily on the competence of the audit personnel assigned to it (Eze and Nwafor, 2019; Okafor and Udeh, 2021).

Political interference is a persistent problem in government auditing. Auditors may face pressure from political appointees or elected officials to suppress or modify findings that could be embarrassing or politically damaging. This pressure can be subtle (e.g., suggestion to “reconsider” a finding) or overt (e.g., threats to cut audit budgets or remove auditors). Even when auditors are professionally committed to independence, the threat of retaliation can have a chilling effect. For FMBN, which operates under the oversight of multiple political bodies, including the National Assembly and the Federal Executive Council, the risk of political interference in the audit process is significant. The extent to which this affects audit quality is an important area of investigation (Ogbeifun, 2019; Oyo-Ita, 2019).

The late or non-submission of accounts by government organizations is a chronic problem that severely undermines the effectiveness of auditing. For an audit to be conducted, the organization must first prepare its financial statements. If these statements are submitted late (or not at all), the audit is delayed or impossible. In Nigeria, many government organizations submit their accounts months or even years after the statutory deadline. By the time the audit is completed and the report is submitted to the National Assembly, the information may be stale and the opportunity for corrective action may have passed. For FMBN, which has a statutory requirement to submit its annual accounts within a specified period, compliance with this requirement affects the timeliness and relevance of the audit (CBN, 2021; FIRS, 2020).

Even when audits are completed and reports are submitted, the enforcement of audit recommendations is often weak. The Public Accounts Committees of the National Assembly are responsible for reviewing audit reports, summoning accounting officers to explain irregularities, and recommending sanctions. However, these committees face their own challenges, including high turnover of members (due to elections), lack of technical expertise, political considerations, and heavy workloads. Many audit reports are not fully considered, and recommendations are not implemented. Cases of financial irregularities reported by auditors may never be prosecuted or recovered. For FMBN, the impact of the audit depends in part on whether its management implements audit recommendations and whether oversight bodies enforce accountability (Nwankwo and Okeke, 2020; Okafor and Udeh, 2020).

The independence of internal audit units within government organizations is another significant problem. Internal auditors are employees of the organization they audit, which creates an inherent conflict of interest. They may be reluctant to report findings that could embarrass their management or lead to budget cuts. They may be transferred, demoted, or dismissed if they are perceived as “too aggressive.” Internal audit reports may be reviewed and edited by management before being submitted to higher authorities. For effective internal auditing to occur, internal auditors must have organizational independence, direct access to the board or audit committee, and protection from retaliation. In FMBN, as in many government organizations, the extent to which internal audit enjoys genuine independence is questionable (Mellett, 2019; Eze and Nwafor, 2019).

Despite these problems, there are significant prospects for improving auditing in government organizations. Technological advancements offer the potential for more efficient and effective audits through data analytics, continuous auditing, and automated testing. The adoption of International Public Sector Accounting Standards (IPSAS) and International Standards of Supreme Audit Institutions (ISSAI) provides frameworks for best practices. Ongoing public financial management reforms, including the Treasury Single Account (TSA), the Government Integrated Financial Management Information System (GIFMIS), and the Integrated Payroll and Personnel Information System (IPPIS), create opportunities for improved financial control and auditability. There is also growing public demand for accountability and transparency, which creates political pressure for stronger audits (Chan, 2018; IPSASB, 2021).

For FMBN specifically, the prospects for improved auditing include: leveraging the bank’s existing financial systems and controls (which are likely more sophisticated than in many government organizations due to its banking operations), strengthening the internal audit function to become a strategic partner rather than just a compliance check, enhancing cooperation between internal and external auditors to avoid duplication and improve coverage, and using audit findings to improve operational efficiency and effectiveness. The bank’s management could also use audit reports as a tool for improving governance and risk management, rather than viewing audits as a threat (FMBN, 2023; Adebayo and Oyedokun, 2020).

The role of the audit committee is critical to addressing the problems of auditing in government organizations. The audit committee, typically composed of non-executive directors or external members, oversees the audit process, reviews audit findings, monitors management’s response, and ensures auditor independence. For FMBN, an effective audit committee could mitigate political interference, protect internal auditors, and ensure that audit recommendations are taken seriously. The composition, independence, expertise, and effectiveness of the audit committee are therefore key determinants of audit quality and impact (FRCN, 2014; Okafor and Udeh, 2021).

The relationship between the external auditor (the Office of the Auditor-General of the Federation or its appointed representatives) and the internal audit function is also important. When these two audit functions work in isolation, there is duplication of effort, gaps in coverage, and inefficiency. When they work collaboratively, sharing audit plans, findings, and reports, the overall audit coverage improves, and the burden on the organization is reduced. For FMBN, enhancing collaboration between internal and external audit is a prospect for improving audit effectiveness without increasing costs (Eze and Nwafor, 2020; Oyo-Ita, 2019).

Finally, the prospects for auditing in government organizations depend on political will and leadership commitment. If the President, the National Assembly, the Minister of Finance, and other key leaders prioritize accountability and act on audit findings, then auditing can be a powerful tool for improving governance. If they ignore audit reports or protect those who mismanage public funds, then auditing will remain a ritualistic exercise with little impact. For FMBN, the commitment of its leadership and of its oversight bodies to act on audit findings is a critical determinant of whether auditing achieves its potential (Ogbeifun, 2019; Adebayo and Oyedokun, 2020).

This study focuses on the Federal Mortgage Bank of Nigeria as a case study because it represents a unique type of government organization: a public financial institution with a social mandate (affordable housing) but also banking operations and financial risks. The auditing problems and prospects at FMBN may differ from those at a typical government ministry or department. By examining FMBN in depth, the study can generate insights that are relevant to other government financial institutions, such as development banks, agricultural banks, and infrastructure finance entities. The findings will contribute to the literature on public sector auditing and provide practical recommendations for improving audit effectiveness in Nigeria (FMBN, 2023; Nwankwo and Okeke, 2020).

1.2 Statement of the Problem

The Federal Mortgage Bank of Nigeria (FMBN), as a government organization entrusted with billions of Naira in public funds (including the National Housing Fund contributions from workers and government allocations), is required by law to undergo regular audits to ensure accountability, transparency, and proper use of resources. However, evidence suggests that auditing in government organizations like FMBN faces significant problems that may undermine its effectiveness. These problems include inadequate audit funding, shortage of qualified audit staff, political interference in the audit process, late submission of accounts, weak enforcement of audit recommendations, lack of internal audit independence, and the complexity of auditing specialized financial operations (mortgage lending, property management). As a result, audit reports may be delayed, incomplete, ignored, or fail to detect material misstatements, irregularities, or inefficiencies. The consequences of weak auditing include financial losses, mismanagement, corruption, and failure to achieve the bank’s housing mandate. Conversely, there are prospects for improving auditing through technology, public financial management reforms, strengthened audit committees, and collaboration between internal and external audit. However, these prospects are not automatically realized. There is a lack of recent, systematic, empirical research that identifies and analyzes the specific problems facing auditing at FMBN and the realistic prospects for improvement. Therefore, this study is motivated to investigate the problems and prospects of auditing in the Federal Mortgage Bank of Nigeria, and to propose practical solutions for strengthening the audit function and enhancing its contribution to accountability and performance.

1.7 Significance of the Study

This study is significant for several stakeholders. First, the management and staff of the Federal Mortgage Bank of Nigeria (particularly the internal audit department) will benefit from a systematic identification of audit problems and prospects, enabling them to strengthen the audit function, address weaknesses, and enhance the contribution of auditing to accountability and performance. Second, the Office of the Auditor-General of the Federation will gain insights into the specific challenges facing auditing at a government financial institution, informing audit planning, resource allocation, and methodology improvements. Third, the Federal Ministry of Power, Works and Housing (the supervising ministry for FMBN) and the Central Bank of Nigeria (as a regulator) will benefit from understanding the audit effectiveness at FMBN, supporting oversight and intervention decisions. Fourth, the National Assembly (particularly the Public Accounts Committee) will gain evidence on audit problems and prospects, informing legislative oversight, hearings, and recommendations. Fifth, the Federal Ministry of Finance, Budget and National Planning will benefit from insights into public financial management challenges at FMBN, informing budget allocations and reform initiatives. Sixth, other government organizations (especially financial institutions like development banks, agricultural banks, and infrastructure funds) can use the findings as a benchmark for evaluating and improving their own audit functions. Seventh, academics and researchers in public sector auditing, public financial management, and governance will find value in the study’s contribution to the literature on auditing in Nigerian government organizations. Eighth, professional bodies such as the Institute of Chartered Accountants of Nigeria (ICAN) and the Association of National Accountants of Nigeria (ANAN) will gain insights into the challenges facing government auditors, informing training, CPD programs, and advocacy. Ninth, civil society organizations focused on governance and anti-corruption will benefit from evidence on audit weaknesses, supporting their advocacy for stronger accountability mechanisms. Finally, the Nigerian public (including contributors to the National Housing Fund) will benefit indirectly as improved auditing at FMBN leads to better financial management, reduced waste and fraud, and more effective delivery of affordable housing.

1.8 Scope of the Study

This study focuses on the problems and prospects of auditing in government organizations, using the Federal Mortgage Bank of Nigeria (FMBN) as a case study. Geographically, the research is limited to the headquarters of FMBN in Abuja, Nigeria, where the bank’s core financial operations and audit functions are centered. FMBN is a federal government-owned mortgage institution responsible for administering the National Housing Fund and providing affordable housing finance. Content-wise, the study examines the following areas: current auditing practices and procedures (internal and external audit); problems and challenges (funding, staff competence, political interference, late accounts, enforcement of recommendations, independence of internal audit, complexity of operations); impact of problems on audit quality and usefulness; prospects (technology, public financial management reforms, audit committee strengthening, internal-external audit collaboration, leadership commitment); and recommendations for improvement. The study targets management staff (including the Managing Director, Executive Directors), internal auditors, external auditors (representatives of the Auditor-General’s office assigned to FMBN), the audit committee, finance department staff, and oversight body representatives. The time frame for data collection is the cross-sectional period of 2023–2024, though historical audit reports and financial statements (e.g., 5-10 years) will be analyzed. The study does not cover other government organizations (except for comparative context), nor does it cover private sector auditing, nor non-financial government organizations (e.g., ministries, departments, agencies without financial intermediation functions).

CHAPTER TWO: LITERATURE REVIEW

2.1 Conceptual Framework

A conceptual framework is a structural representation of the key concepts or variables in a study and the hypothesized relationships among them. It serves as the analytical lens through which the researcher organizes the study, selects appropriate methodology, and interprets findings. In this study, the conceptual framework is built around three primary constructs: Auditing (the independent variable), Problems of Auditing (the negative dimension of the dependent variable), and Prospects of Auditing (the positive dimension of the dependent variable). Additionally, the framework identifies the specific dimensions of each construct and the moderating variables that influence the relationship (Miles, Huberman, and Saldaña, 2020).

The independent variable, Auditing, refers to the systematic and independent examination of books, accounts, records, and operations of an organization. For the purpose of this study, auditing in a government organization like FMBN is conceptualized along four key types: (a) financial audit (examination of financial statements to ensure they present a true and fair view and comply with accounting standards), (b) compliance or regularity audit (examination of compliance with laws, regulations, budget approvals, and internal policies), (c) performance audit (examination of the economy, efficiency, and effectiveness of operations and programs), and (d) internal audit (ongoing, internal examination of controls, risks, and governance processes). Each type of audit serves different purposes and faces different problems and prospects (Premchand, 2019; Mellett, 2019).

The dependent variable is bifurcated into two interrelated dimensions: Problems and Prospects. The Problems dimension refers to the difficulties, obstacles, challenges, and negative factors that affect the effectiveness of auditing in government organizations. Based on the literature and the Nigerian context, problems are conceptualized along eight major categories: (a) funding problems (inadequate budget for audit offices, affecting scope, depth, and frequency of audits), (b) human resource problems (shortage of qualified audit staff, low salaries, high turnover, lack of specialized skills), (c) political interference (pressure from political appointees or elected officials to suppress or modify findings), (d) timeliness problems (late or non-submission of accounts, delaying audits and reducing relevance), (e) enforcement problems (weak follow-up on audit recommendations, lack of sanctions for non-compliance), (f) independence problems (lack of independence for internal audit, threats to external audit independence), (g) complexity problems (difficulty auditing specialized operations such as mortgage lending, property management, and financial instruments), and (h) institutional problems (weak legal framework, overlapping oversight bodies, lack of coordination between internal and external audit). Each category represents a potential barrier to effective auditing (Adebayo and Oyedokun, 2020; Eze and Nwafor, 2019).

The Prospects dimension refers to the potential or realized opportunities, improvements, and positive outcomes that can enhance the effectiveness of auditing in government organizations. Based on the literature, prospects are conceptualized along six major categories: (a) technological prospects (use of data analytics, continuous auditing, automated testing, and audit management software), (b) public financial management (PFM) reform prospects (implementation of Treasury Single Account, GIFMIS, IPPIS, and other reforms that improve financial control and auditability), (c) audit committee strengthening (improved composition, independence, expertise, and authority of audit committees), (d) internal-external audit collaboration (better coordination, information sharing, and division of responsibilities between internal and external audit), (e) professional development prospects (enhanced training, certification, and continuing professional development for government auditors), and (f) leadership and political will prospects (commitment from top leadership to act on audit findings and prioritize accountability). For FMBN, realizing these prospects depends on how effectively the organization and its oversight bodies address the problems dimension (Chan, 2018; Okafor and Udeh, 2021).

The conceptual framework posits an inverse relationship between problems and audit effectiveness: organizations that experience severe problems (e.g., inadequate funding, political interference, weak enforcement) will have less effective audits, resulting in lower quality audit reports, less detection of irregularities, and less improvement in accountability and performance. Conversely, organizations that successfully mitigate problems will achieve greater audit effectiveness. The framework also posits a positive relationship between prospects and audit effectiveness: organizations that embrace technological advancements, PFM reforms, and other prospects will achieve more effective audits. However, the relationship is not strictly linear; some problems may be unavoidable (e.g., political pressure) but can be managed through appropriate safeguards (Miettinen, 2012; Power, 1997).

An important feature of this conceptual framework is the recognition of moderating variables that influence the problems-audit effectiveness and prospects-audit effectiveness relationships. These moderators include: (a) organizational factors (size, complexity, governance structure, management commitment to accountability), (b) regulatory factors (strength and clarity of audit laws, independence of the Auditor-General), (c) institutional factors (capacity of oversight bodies like Public Accounts Committees, coordination between audit institutions), (d) political factors (level of political will, electoral competitiveness, civil society pressure), (e) economic factors (availability of government resources, economic stability), and (f) social factors (public demand for accountability, media scrutiny). For FMBN, these moderating variables will determine the severity of problems encountered and the extent to which prospects are realized (Ogbeifun, 2019; Oyo-Ita, 2019).

The framework also acknowledges the interdependencies among problems. For example, inadequate funding (a problem) leads to inability to hire and retain qualified staff (human resource problem). Late submission of accounts (timeliness problem) reduces the relevance of audits even if other aspects are high quality. Political interference (political problem) can cause audit reports to be suppressed, reducing enforcement (enforcement problem). The framework suggests that addressing problems requires a holistic approach, as individual problems are often interconnected. For FMBN, this means that improving audit effectiveness may require simultaneously addressing funding, human resources, independence, and enforcement (Eze and Nwafor, 2020; Nwankwo and Okeke, 2021).

The framework also recognizes the dynamic nature of problems and prospects. Some problems may be long-standing (e.g., late submission of accounts), while others may be episodic (e.g., political interference during election years). Some prospects (e.g., technology) may be available now, while others (e.g., full implementation of PFM reforms) may take years to realize. For FMBN, the timing of interventions to address problems and capture prospects is important. The framework suggests that a phased approach, prioritizing the most severe problems and the most achievable prospects, may be most effective (Premchand, 2019; Chan, 2018).

Methodologically, the conceptual framework guides the development of research instruments and analytical procedures. Interview guides and survey questionnaires are structured to capture each type of audit (financial, compliance, performance, internal), each category of problems (funding, human resources, political interference, timeliness, enforcement, independence, complexity, institutional), and each category of prospects (technology, PFM reforms, audit committee, collaboration, professional development, leadership). Questions probe specific examples from FMBN’s experience. The framework also guides the analysis of secondary data, including audit reports, Public Accounts Committee proceedings, financial statements, and internal audit charters (Creswell and Creswell, 2018; Saunders, Lewis, and Thornhill, 2019).

Empirical studies that have employed similar conceptual frameworks in other government audit contexts provide validation for this approach. For example, studies on supreme audit institutions in developing countries have identified funding, staff competence, and political interference as the top three problems affecting audit effectiveness. Studies on performance auditing in European governments have found that leadership commitment and collaboration between auditors were the strongest predictors of audit impact. In Nigeria, research on government auditing has found that weak enforcement and late submission of accounts are the most persistent problems, while technology adoption and PFM reforms offer the greatest prospects for improvement. These findings support the relevance of the current framework for FMBN (Adebayo and Oyedokun, 2019; Eze and Nwafor, 2021; Okafor and Udeh, 2020).

The conceptual framework also addresses the unique characteristics of FMBN as a government financial institution. Unlike a typical government ministry or department, FMBN has banking operations (mortgage lending, deposit mobilization, investment management) that require specialized audit skills. The bank is subject to both government auditing standards (from the Auditor-General) and banking regulations (from the CBN). This dual oversight creates additional complexity but also additional prospects for audit improvement. The framework includes these unique characteristics as moderating variables that affect the problems and prospects of auditing (FMBN, 2023; Nwankwo and Okeke, 2020).

Visually, the conceptual framework for this study can be represented as a diagram with “Auditing” (independent variable) at the left, with four boxes (financial audit, compliance audit, performance audit, internal audit). From auditing, two arrows diverge: one pointing to “Problems” (negative outcomes) and one pointing to “Prospects” (positive outcomes). The Problems box is broken into eight categories (funding, human resources, political interference, timeliness, enforcement, independence, complexity, institutional). The Prospects box is broken into six categories (technology, PFM reforms, audit committee, collaboration, professional development, leadership). From both Problems and Prospects, arrows point to “Audit Effectiveness” (outcome). Above the diagram are placed the moderating variables (organizational, regulatory, institutional, political, economic, social). This visual representation aids readers in quickly grasping the hypothesized relationships (Miles et al., 2020).

In summary, the conceptual framework of this study provides a clear, logical, and empirically grounded structure for investigating the problems and prospects of auditing in government organizations at the Federal Mortgage Bank of Nigeria. By disaggregating auditing into four types, problems into eight categories, and prospects into six categories, and by acknowledging the moderating variables and interdependencies, the framework enhances the validity and reliability of the research findings. It also serves as a bridge between the theoretical foundations (discussed in section 2.2) and the empirical investigation (chapters three and four) (Creswell and Creswell, 2018).

2.2 Theoretical Framework

A theoretical framework is a collection of interrelated concepts, definitions, and propositions that present a systematic view of phenomena by specifying relationships among variables, with the purpose of explaining and predicting those phenomena. In this study, five major theories are adopted to explain the problems and prospects of auditing in government organizations: the Agency Theory, the Stewardship Theory, the Institutional Theory, the Public Interest Theory, and the Audit Expectation Gap Theory. These theories collectively provide a robust lens for understanding why auditing problems arise, why prospects exist, and how auditing can be improved (Jensen and Meckling, 1976; Davis, Schoorman, and Donaldson, 1997; DiMaggio and Powell, 1983; Posner and Sunstein, 2018; Liggio, 1974).

2.2.1 Agency Theory

Agency Theory, developed by Jensen and Meckling (1976), is one of the most influential theories in corporate governance, public financial management, and auditing research. The theory describes the relationship between principals (citizens and their elected representatives) and agents (government officials and civil servants) who are entrusted with public funds. Agency Theory posits that agents may not always act in the best interests of principals due to information asymmetry (agents have more information about their actions and spending decisions than principals do) and divergent interests (agents may pursue personal goals such as wealth, power, or career advancement rather than citizen welfare). This divergence creates agency costs, which include monitoring costs (expenditures to oversee agent behavior) and bonding costs (expenditures by agents to assure principals of their fidelity) (Jensen and Meckling, 1976; Premchand, 2019).

In the context of this study, Agency Theory explains the fundamental need for auditing in government organizations like FMBN. Because citizens (principals) cannot directly observe every spending and operational decision made by government officials (agents), they rely on audits to provide independent assurance that public funds are managed properly and that agents are complying with laws and regulations. Auditing reduces information asymmetry and allows principals to detect and deter agent opportunism (such as unauthorized spending, procurement fraud, embezzlement, or inefficiency). The theory predicts that audit effectiveness will be highest when monitoring is independent, rigorous, and accompanied by sanctions for non-compliance. The problems of auditing (e.g., political interference, weak enforcement, inadequate funding) can be understood as factors that weaken the monitoring function, increasing agency costs and reducing accountability (Mellett, 2019; Chan, 2018).

Agency Theory also explains why internal audit is critical but faces independence problems. Internal auditors are agents of the organization but are also employees, creating a conflict of interest. They may be reluctant to report findings that would embarrass management (their direct supervisors). The theory predicts that internal audit effectiveness depends on organizational structures that insulate auditors from management pressure, such as reporting directly to the board or audit committee. For FMBN, Agency Theory suggests that strengthening internal audit independence and providing protection from retaliation are essential for effective auditing (Eze and Nwafor, 2019; Okafor and Udeh, 2020).

Empirical research has supported Agency Theory predictions about auditing. Studies have found that stronger audit functions (higher quality, more independent, better resourced) are associated with lower levels of corruption, better financial management, and higher public trust. In Nigeria, research has found that government organizations with more effective audits have fewer audit queries and better compliance with financial regulations. For FMBN, Agency Theory suggests that addressing problems such as political interference and weak enforcement is essential for audit effectiveness (Adebayo and Oyedokun, 2020; Oyo-Ita, 2019).

2.2.2 Stewardship Theory

Stewardship Theory, developed by Davis, Schoorman, and Donaldson (1997), offers a contrasting perspective to Agency Theory. While Agency Theory assumes that agents are self-interested and opportunistic, Stewardship Theory posits that managers and public officials are inherently trustworthy, responsible, and motivated to act in the best interests of the organization and its stakeholders. Stewards derive satisfaction from organizational achievement, collective success, and the responsible management of resources placed in their care. In the public sector context, Stewardship Theory suggests that most government officials are public servants who genuinely want to use public funds efficiently and effectively. They do not require constant monitoring and punitive controls; rather, they need the tools, training, and support to fulfill their stewardship responsibilities (Davis et al., 1997; Mellett, 2019).

In the context of this study, Stewardship Theory explains the role of auditing in supporting, rather than merely controlling, government organizations. From a stewardship perspective, auditing provides information that stewards (government officials) need to demonstrate that they have been good stewards of public funds. Auditors are partners in accountability, not adversaries. The theory suggests that auditing problems such as adversarial relationships between auditors and auditees, lack of cooperation, and defensive attitudes can be mitigated by fostering a stewardship culture. For FMBN, Stewardship Theory implies that auditing prospects include building a collaborative relationship between auditors and management, where both are committed to the same goal of responsible financial management (Premchand, 2019; Ogbeifun, 2019).

Stewardship Theory also explains why excessive or overly rigid auditing can be counterproductive. If audit processes are so burdensome that they slow down legitimate operations, they may frustrate stewards and undermine their motivation. Similarly, if audits are designed on the assumption that every employee is a potential fraudster, they may create a culture of distrust and low morale. For FMBN, Stewardship Theory suggests that auditing should be designed to balance the need for assurance with the need for efficiency and should be implemented in a way that respects and supports the professionalism of staff (Eze and Nwafor, 2020).

Empirical research has found that government organizations with a stewardship culture (characterized by transparency, accountability, and public service motivation) have better financial management outcomes, even when formal audit controls are relatively light. For FMBN, fostering a stewardship culture may be as important as strengthening audit procedures (Adebayo and Oyedokun, 2019).

2.2.3 Institutional Theory

Institutional Theory, developed by DiMaggio and Powell (1983) and Scott (2001), explains why organizations within a given field tend to adopt similar structures, practices, and processes over time. The theory identifies three mechanisms of institutional isomorphism: coercive isomorphism (pressure from regulators, laws, or powerful organizations), mimetic isomorphism (copying successful competitors in response to uncertainty), and normative isomorphism (pressure from professional bodies, training, and networks). According to Institutional Theory, organizations adopt practices such as auditing not only because they improve technical performance but also because they confer legitimacy, which enhances survival and access to resources (DiMaggio and Powell, 1983).

In the context of this study, Institutional Theory explains why FMBN and other government organizations have adopted specific audit practices and structures, and why problems persist. Coercive pressures include the Constitution, the Audit Act, the FMBN Act, and directives from the Office of the Auditor-General. Mimetic pressures include observing other mortgage banks or financial institutions (including private sector ones) and copying their audit practices. Normative pressures include the influence of professional bodies (ICAN, ANAN) that promote certain auditing standards as professional norms. The theory suggests that some audit practices may be adopted “ceremonially” to gain legitimacy without actually being implemented effectively (decoupling), which explains why problems persist despite formal compliance (Chan, 2018; Okafor and Udeh, 2021).

Institutional Theory also explains why prospects such as technology adoption and PFM reforms may be adopted slowly or incompletely. Organizations may adopt the appearance of reform (e.g., purchasing audit software) without changing underlying practices. The theory suggests that for reforms to be effective, there must be not only formal adoption but also cultural change and internalization of new norms. For FMBN, this implies that addressing audit problems requires more than policy changes; it requires changing the organizational culture and ensuring that audit practices are genuinely implemented, not just symbolically adopted (Nwankwo and Okeke, 2020).

Empirical research has found that institutional pressures (especially coercive pressures from regulators) are the strongest drivers of audit practice adoption in government organizations. However, the gap between formal adoption and actual implementation (decoupling) is common, particularly when organizations face conflicting pressures or lack capacity. For FMBN, Institutional Theory suggests that strengthening enforcement and monitoring of compliance is essential to reduce decoupling and ensure that audit practices are effective (Eze and Nwafor, 2021).

2.2.4 Public Interest Theory

Public Interest Theory, rooted in welfare economics and regulatory theory, posits that government intervention and regulation (including auditing) are justified when they serve the broader public interest. According to this theory, auditing in government organizations is intended to protect the public interest by ensuring that public funds are used properly, that services are delivered efficiently, and that public officials are accountable. Auditing serves the public interest by providing independent assurance, detecting and deterring fraud and mismanagement, and providing information for legislative oversight. The theory assumes that auditors act as guardians of the public interest, prioritizing citizen welfare over the interests of the audited organization or their own career advancement (Posner and Sunstein, 2018; Chan, 2018).

In the context of this study, Public Interest Theory explains why auditing problems are particularly serious in government organizations. When audits are ineffective due to funding shortages, political interference, or weak enforcement, the public interest is harmed. Citizens are denied the assurance that their tax dollars are being spent properly. Corruption and mismanagement go undetected. Oversight bodies lack reliable information. The theory suggests that addressing audit problems is not merely a technical or administrative matter but a moral and democratic imperative. For FMBN, where the bank manages mandatory contributions from workers (the National Housing Fund), the public interest in effective auditing is particularly high (Ogbeifun, 2019; Oyo-Ita, 2019).

Public Interest Theory also provides a normative standard for evaluating audit prospects. Technological advancements, PFM reforms, and other prospects should be judged by whether they better serve the public interest—i.e., whether they improve accountability, reduce corruption, and enhance service delivery. For FMBN, the prospects of auditing should be evaluated not only on technical grounds (e.g., efficiency) but also on whether they increase the public’s trust in the bank and its ability to deliver affordable housing (Adebayo and Oyedokun, 2020).

Empirical research has found that supreme audit institutions that prioritize public interest (e.g., by publishing audit reports, engaging with civil society, and following up on recommendations) are more effective at improving government accountability. For FMBN, Public Interest Theory suggests that transparency (e.g., making audit reports public) and stakeholder engagement (e.g., allowing civil society to review audit findings) can enhance audit effectiveness (Okafor and Udeh, 2020).

2.2.5 Audit Expectation Gap Theory

Audit Expectation Gap Theory, associated with Liggio (1974) and later researchers, explains the difference between what the public and other stakeholders expect from an audit and what auditors actually do. The expectation gap has two components: the “reasonableness gap” (the difference between what society expects from auditors and what auditors can reasonably be expected to accomplish) and the “performance gap” (the difference between what auditors can reasonably accomplish and what they actually accomplish). The expectation gap leads to disappointment, criticism, and sometimes legal action against auditors when stakeholders believe auditors failed to detect fraud or other problems (Liggio, 1974; Porter, 1993).

In the context of this study, Audit Expectation Gap Theory explains some of the problems of auditing in government organizations. Stakeholders (citizens, legislators, civil society) may expect auditors to detect all fraud, to prevent corruption, and to guarantee that public funds are spent perfectly. In reality, audits have inherent limitations: they are based on sampling, not 100% examination; they rely on management representations; and they may not detect sophisticated fraud. When stakeholders’ expectations exceed what auditors can reasonably deliver (the reasonableness gap), they may be dissatisfied even with high-quality audits. Conversely, when auditors fail to perform up to professional standards (the performance gap), the dissatisfaction is justified (Power, 1997; Miettinen, 2012).

Audit Expectation Gap Theory also explains why communication between auditors and stakeholders is critical. Many problems and prospects of auditing relate to managing expectations. For FMBN, auditors must clearly communicate the scope and limitations of their work to the bank’s board, management, and oversight bodies. They must explain that a clean audit opinion does not guarantee that fraud does not exist, only that the financial statements are fairly presented. The theory suggests that reducing the expectation gap requires both improved auditor performance (narrowing the performance gap) and improved communication about what audits can and cannot do (narrowing the reasonableness gap) (Eze and Nwafor, 2020; Okafor and Udeh, 2021).

Empirical research has consistently found a significant audit expectation gap in both private and public sector auditing. In the public sector, the gap is often wider because stakeholders may have unrealistic expectations about what auditors can achieve. For FMBN, the theory suggests that prospects for improving auditing include enhanced communication, stakeholder education, and clearer audit reporting that explicitly addresses the limitations of the audit (Adebayo and Oyedokun, 2019).

2.2.6 Synthesis of the Five Theories

Taken together, Agency Theory, Stewardship Theory, Institutional Theory, Public Interest Theory, and Audit Expectation Gap Theory provide a comprehensive, multi-layered theoretical foundation for this study. Agency Theory explains the monitoring role of auditing and why problems like political interference and weak enforcement undermine accountability. Stewardship Theory complements Agency Theory by recognizing that most public officials are trustworthy and that auditing should enable rather than constrain. Institutional Theory explains why audit practices are adopted (isomorphic pressures) and why there may be gaps between formal policies and actual practices (decoupling). Public Interest Theory provides the normative justification for auditing: it serves the broader public good. Audit Expectation Gap Theory explains the disappointment and criticism that often surround public sector audits, highlighting the importance of communication (Jensen and Meckling, 1976; Davis et al., 1997; DiMaggio and Powell, 1983; Posner and Sunstein, 2018; Liggio, 1974).

The synthesis of these theories also guides empirical testing and practical recommendations. Research questions and hypotheses derived from this theoretical framework can focus on: from Agency Theory, the effect of political interference and weak enforcement on audit effectiveness; from Stewardship Theory, the extent to which a collaborative audit culture exists at FMBN; from Institutional Theory, whether audit practices are substantively or symbolically adopted; from Public Interest Theory, whether auditing serves the public interest at FMBN; and from Audit Expectation Gap Theory, whether there is a gap between stakeholder expectations and actual audit performance. The framework suggests that improving auditing at FMBN requires attention to all five theoretical dimensions: strengthening monitoring (Agency), fostering stewardship culture (Stewardship), ensuring substantive implementation (Institutional), prioritizing the public interest (Public Interest), and managing expectations (Expectation Gap) (Creswell and Creswell, 2018).

In conclusion, the theoretical framework of this study is firmly anchored in five well-established, complementary theories: Agency Theory (Jensen and Meckling, 1976), Stewardship Theory (Davis et al., 1997), Institutional Theory (DiMaggio and Powell, 1983), Public Interest Theory (Posner and Sunstein, 2018), and Audit Expectation Gap Theory (Liggio, 1974). These theories collectively explain the problems and prospects of auditing in government organizations, the mechanisms through which auditing adds value, the institutional pressures that shape audit practices, the normative purpose of auditing, and the expectations that stakeholders have of auditors. The framework provides a solid foundation for the conceptual framework (section 2.1), the research methodology (chapter three), and the interpretation of findings (chapters four and five) (Miles et al., 2020).
