EFFECTIVENESS OF AUDIT REPORT ON THE IMPROVEMENT OF FINANCIAL MANAGEMENT IN FEDERAL PARASTATALS: A Study of Educational System

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 and to ensure that financial transactions comply with relevant laws, regulations, and internal policies. In the public sector, 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).

An audit report is the formal output of the audit process, containing the auditor’s opinion, findings, conclusions, and recommendations. The audit report is addressed to the relevant authority (e.g., management, board, audit committee, legislature) and is a public document (in the case of public sector audits). The audit report typically includes: (a) the auditor’s opinion on the financial statements (unqualified, qualified, adverse, or disclaimer), (b) a report on internal controls over financial reporting (identifying weaknesses and recommending improvements), (c) a compliance report (identifying instances of non-compliance with laws and regulations), (d) a performance audit report (evaluating economy, efficiency, and effectiveness), and (e) management letters containing detailed recommendations for improvement. The effectiveness of the audit report depends on whether the findings and recommendations lead to corrective action by management and oversight bodies (INTOSAI, 2020; Hayes, Dassen, Schilder, and Wallage, 2019).

Financial management in the public sector encompasses the planning, directing, monitoring, organizing, and controlling of financial resources to achieve government objectives. Key elements of public sector financial management include: (a) budgeting (preparation, approval, execution, and monitoring), (b) accounting (recording and reporting financial transactions), (c) internal control (policies and procedures to safeguard assets and ensure compliance), (d) internal audit (independent assurance on risk management and control), (e) external audit (independent examination by the Auditor-General), (f) legislative oversight (review of audit reports by the Public Accounts Committee), and (g) accountability (answerability and enforceability). Effective financial management ensures that public funds are used as intended, waste and fraud are minimized, and services are delivered to citizens (Premchand, 2019; Chan, 2018).

Federal parastatals in Nigeria are government-owned or government-controlled entities established by Acts of the National Assembly to perform specific public functions. Parastatals have some operational autonomy but are subject to government oversight (budget approval, financial regulations, audit). In the educational system, federal parastatals include: (a) federal universities (e.g., University of Lagos, University of Nigeria, Nsukka, Ahmadu Bello University), (b) federal polytechnics, (c) federal colleges of education, (d) federal government colleges (unity schools), (e) the National Universities Commission (NUC), (f) the National Board for Technical Education (NBTE), (g) the National Commission for Colleges of Education (NCCE), (h) the Universal Basic Education Commission (UBEC), (i) the Tertiary Education Trust Fund (TETFund), and (j) other educational agencies. These parastatals receive significant funding from the federal government (budget allocations) and from internally generated revenue (school fees, consultancy, research grants). As public entities, they are accountable to the Federal Government, the National Assembly, the Office of the Auditor-General of the Federation (OAuGF), and the citizens of Nigeria for the use of public funds (Federal Ministry of Education, 2022; Okafor and Udeh, 2020).

The educational system in Nigeria has faced significant financial management challenges, including: (a) inadequate funding relative to needs, (b) poor budget preparation and execution, (c) weak internal controls, (d) delayed financial reporting, (e) unauthorized expenditures, (f) procurement irregularities, (g) payroll fraud (ghost workers), (h) mismanagement of internally generated revenue (IGR), (i) inadequate maintenance of infrastructure, and (j) corruption. These challenges have led to audit queries from the Office of the Auditor-General of the Federation (OAuGF) and the National Assembly’s Public Accounts Committee (PAC). Audit reports on educational parastatals have consistently highlighted weaknesses in financial management, including: lack of supporting documents for expenditures, unauthorized contract awards, non-remittance of deducted taxes and pensions, and weak internal controls (Oyo-Ita, 2019; Nwankwo and Okeke, 2020).

The effectiveness of audit reports in improving financial management depends on several factors. Audit quality: The audit report must be accurate, complete, timely, and based on sufficient appropriate audit evidence. Poor quality audits produce unreliable reports that are ignored. Independence of the auditor: The Office of the Auditor-General of the Federation (OAuGF) must be independent of the executive branch to report findings without fear or favour. Constitutional and statutory provisions protect the Auditor-General’s independence, but political pressures may still influence audit outcomes. Management response: Management must take audit findings seriously and implement recommendations. Weak management response (ignoring reports, delaying action, retaliating against auditors) undermines effectiveness. Audit committee effectiveness: An effective audit committee (board of directors or governing council) oversees the audit process, reviews findings, and monitors management’s response. Legislative oversight: The Public Accounts Committee (PAC) of the National Assembly reviews audit reports, summons accounting officers to explain findings, and recommends sanctions. Weak PACs (lack of expertise, political interference, inadequate resources) reduce the effectiveness of audit reports. Follow-up: The OAuGF must conduct follow-up audits to assess whether management has implemented recommendations. Without follow-up, management may ignore reports (Oyo-Ita, 2019; Ogbeifun, 2019).

The audit process for federal parastatals follows a defined cycle. Planning: The OAuGF plans the audit based on risk assessment (financial statement risk, internal control risk, compliance risk). Execution: Auditors perform audit procedures (testing controls, substantive testing of transactions, analytical procedures). Findings and recommendations: Auditors identify weaknesses, irregularities, and non-compliance, and recommend corrective action. Reporting: The audit report is issued to management (management letter) and to the National Assembly (audit opinion and detailed findings). Follow-up: Management responds to audit findings with an action plan. The OAuGF conducts follow-up audits to assess implementation. The PAC reviews audit reports, summons accounting officers, and recommends sanctions (e.g., recovery of funds, surcharge, prosecution) (INTOSAI, 2020; Hayes et al., 2019).

The effectiveness of audit reports can be measured using several indicators: (a) implementation rate of audit recommendations: percentage of recommendations fully implemented by management, (b) time to implement: average time between audit report issuance and implementation, (c) reduction in audit queries: decline in the number and severity of repeated audit findings, (d) improvement in financial reporting: timeliness and quality of financial statements, (e) compliance with financial regulations: reduction in unauthorized expenditures, improved procurement compliance, (f) recovery of misappropriated funds: amounts recovered following audit recommendations, (g) sanctions imposed: number of accounting officers surcharged, suspended, or prosecuted following audit findings, and (h) stakeholder satisfaction: perception of PAC members, civil society, and citizens on audit effectiveness (Okafor and Udeh, 2021).

The educational system parastatals face unique financial management challenges that affect the effectiveness of audit reports. Complex funding sources: Federal educational parastatals receive funding from multiple sources: government budget allocations, TETFund interventions, internally generated revenue (school fees, consultancy, research grants), development partner grants, and alumni donations. Each funding source has different reporting requirements, increasing complexity. Decentralised financial management: Larger parastatals (e.g., federal universities) have decentralised financial management (faculties, departments, institutes, centres), increasing the risk of weak controls and fragmentation. High staff turnover: Frequent changes in accounting officers (vice-chancellors, registrars, bursars) may disrupt financial management and audit follow-up. Political interference: Educational parastatals may face political pressure (e.g., from legislators, ministers) to award contracts to favoured suppliers, employ unqualified staff, or admit students without payment, affecting financial management (Ogbeifun, 2019; Eze and Nwafor, 2020).

The Office of the Auditor-General of the Federation (OAuGF) has faced challenges in auditing federal parastatals effectively. Inadequate funding: The OAuGF is often underfunded, limiting its ability to hire qualified auditors, provide training, invest in technology (computer-assisted audit tools CAATs), and conduct comprehensive audits. Staffing shortages: The OAuGF has a shortage of qualified auditors, particularly those with specialised skills (IT auditing, performance auditing, forensic auditing). Late submission of accounts: Many federal parastatals submit their financial statements late (months or years after the statutory deadline), delaying audits and reducing the timeliness of audit reports. Access to records: Auditors may face difficulties obtaining complete records from parastatals (missing vouchers, incomplete ledgers, lack of supporting documents). Political pressure: Auditors may face pressure from political appointees or senior officials to suppress adverse findings or modify audit opinions (Oyo-Ita, 2019; Adebayo and Oyedokun, 2019).

The Public Accounts Committee (PAC) of the National Assembly plays a critical role in ensuring the effectiveness of audit reports. The PAC reviews audit reports from the OAuGF, summons accounting officers (e.g., Vice-Chancellors, Registrars, Bursars) to explain audit findings, requests documents, and recommends sanctions (e.g., surcharge, recovery of funds, prosecution). The PAC’s effectiveness depends on: (a) technical expertise of members (understanding of accounting, auditing, and public financial management), (b) independence from the executive branch, (c) resources for staff and consultants, (d) timeliness of audit reports (delayed reports reduce relevance), (e) follow-up on recommendations, and (f) political will to sanction wrongdoers. Weak PACs undermine the effectiveness of audit reports (Nwankwo and Okeke, 2020; Oyo-Ita, 2019).

The effectiveness of audit reports in improving financial management in federal educational parastatals is an empirical question. Some studies have found that audit reports lead to improvements in financial management (increased compliance, reduced irregularities, recovery of funds). Other studies have found that audit reports have limited impact due to weak enforcement, political interference, and inadequate follow-up. In Nigeria, the effectiveness of audit reports has been questioned, as audit reports often highlight the same weaknesses year after year (e.g., unauthorized expenditures, missing documents, weak internal controls), indicating that recommendations are not being implemented (Adebayo and Oyedokun, 2020; Okafor and Udeh, 2021).

Finally, this study focuses on the educational system (federal universities, polytechnics, colleges of education, and other educational parastatals) as a case study because the educational sector receives significant public funding and is critical to national development. By examining the effectiveness of audit reports on improving financial management in federal educational parastatals, the study can provide insights applicable to other sectors and inform policies to strengthen audit effectiveness, financial management, and accountability (Yin, 2018; Creswell and Creswell, 2018).

1.2 Statement of Research Problem

The Office of the Auditor-General of the Federation (OAuGF) audits federal parastatals annually and issues audit reports containing findings, recommendations, and audit opinions. These audit reports are submitted to the National Assembly, reviewed by the Public Accounts Committee (PAC), and made public. The expectation is that audit reports will lead to improvements in financial management, including: (a) correction of identified weaknesses (internal controls, procurement, reporting), (b) recovery of misappropriated funds, (c) sanctioning of erring officials, (d) improved compliance with financial regulations, and (e) enhanced accountability to citizens. However, evidence suggests that audit reports may not be achieving these objectives effectively. Specific problems include:

1. Persistent audit queries: The OAuGF’s annual reports highlight the same financial management weaknesses year after year (e.g., unauthorized expenditures, missing documents, weak internal controls), indicating that recommendations are not being implemented.
2. Slow implementation of recommendations: Even when management agrees to implement recommendations, implementation is often delayed (years) or never completed.
3. Weak enforcement: The PAC may summon accounting officers but rarely imposes meaningful sanctions (surcharge, suspension, prosecution). Without credible sanctions, management has little incentive to implement audit recommendations.
4. Late audit reports: Audit reports are often submitted to the PAC years after the end of the fiscal year (e.g., 2017 audit report submitted in 2020). Delayed reports reduce their relevance and timeliness for corrective action.
5. Limited audit coverage: The OAuGF has limited resources (funding, staff) to conduct comprehensive audits of all federal parastatals. Some parastatals are audited only every few years, or audit scope is limited.
6. Weak follow-up: The OAuGF lacks a systematic follow-up process to track implementation of audit recommendations. Without follow-up, management may ignore reports.
7. Political interference: Accounting officers (e.g., Vice-Chancellors) may be politically connected, and PAC members may be reluctant to sanction them due to political party affiliations.
8. Lack of stakeholder engagement: Audit reports are technical and not widely disseminated or understood by citizens, civil society, and the media, limiting public pressure for accountability.
9. Educational parastatals specific challenges: Federal educational parastatals have unique challenges (complex funding sources, decentralised management, high staff turnover, political interference) that may reduce the effectiveness of audit reports.

There is a lack of recent, systematic, empirical research that evaluates the effectiveness of audit reports on the improvement of financial management in federal parastatals, particularly in the educational system. Therefore, this study is motivated to investigate the effectiveness of audit reports on the improvement of financial management in federal parastatals, with a focus on the educational system.

1.3 Objectives of the Study

3. To assess the extent to which audit recommendations have been implemented by management of federal educational parastatals.
4. To evaluate the effectiveness of audit reports in improving financial management outcomes (financial reporting timeliness, internal control strength, compliance with regulations, recovery of funds) in federal educational parastatals.
5. To identify the factors (management response, audit committee effectiveness, PAC effectiveness, follow-up, political interference) that affect the effectiveness of audit reports.
6. To assess the role of the Public Accounts Committee (PAC) in enforcing audit recommendations.
7. To propose recommendations for improving the effectiveness of audit reports in enhancing financial management in federal parastatals.

1.7 Significance of the Study

This study is significant for several stakeholders:

Office of the Auditor-General of the Federation (OAuGF) : The findings will inform the OAuGF on the effectiveness of its audit reports, enabling the office to improve audit quality, follow-up processes, and reporting formats to enhance impact.

Public Accounts Committee (PAC) : The findings will inform PAC members and staff on the effectiveness of their oversight role, enabling them to strengthen hearings, tracking of recommendations, and enforcement mechanisms.

Federal Educational Parastatals (Management) : The findings will help management understand which audit recommendations are most frequently implemented and which are ignored, enabling them to prioritise corrective action and strengthen financial management.

Governing Councils and Audit Committees: The findings will inform governing councils on their oversight role, enabling them to monitor management’s implementation of audit recommendations more effectively.

National Assembly: The findings will inform the Senate and House of Representatives on the effectiveness of the PAC and the OAuGF, enabling legislative reforms to strengthen audit effectiveness.

Federal Ministry of Education: The findings will inform the Ministry on financial management challenges in educational parastatals, enabling policy reforms and capacity-building initiatives.

Civil Society Organizations (CSOs) and Citizens: The findings will provide evidence for CSOs to advocate for stronger audit follow-up, transparency, and accountability in educational parastatals.

Academics and Researchers: The study contributes to the literature on public sector auditing, audit effectiveness, and financial management in developing countries.

International Development Partners (World Bank, IMF, DFID/UKAID) : The findings will inform technical assistance programs on public financial management, audit reform, and anti-corruption.

The Nigerian Educational System: Improved financial management in educational parastatals will lead to better use of public funds, improved infrastructure, and enhanced educational outcomes.

1.8 Limitations of the Study

This study acknowledges several limitations:

1. Data Availability: Access to detailed audit reports, management responses, and PAC proceedings may be restricted due to confidentiality or security concerns. The study will rely on publicly available audit reports (OAuGF website) and information from respondents.
2. Social Desirability Bias: Management respondents may overstate their implementation of audit recommendations (social desirability bias). The study will triangulate responses with documentary evidence (management letters, follow-up audits).
3. Recall Bias: Respondents may not accurately recall audit findings or implementation actions for older reports (e.g., 2018). The study will focus on recent reports (2020-2023) to minimise recall bias.
4. Sample Size: The number of federal educational parastatals is limited (approx. 100). The sample may not be representative of all parastatals, but the study will use a stratified sampling approach (by type: universities, polytechnics, colleges, schools).
5. Causality: It may be difficult to isolate the effect of audit reports from other factors affecting financial management (e.g., new management, new regulations, increased funding). The study will use qualitative methods (document analysis, interviews) to understand causal mechanisms.
6. Time Lag: The full effect of audit reports may take years to materialise (e.g., recovery of funds through legal action). The study’s time frame (5 years) may not capture long-term effects.
7. Generalizability: Findings may not be generalizable to non-educational parastatals (e.g., health, transportation, energy). The study focuses on educational parastatals, but findings may have relevance for other sectors.
8. Political Sensitivity: PAC hearings and audit findings may be politically sensitive; respondents may be reluctant to discuss sensitive cases. The study will anonymise responses and focus on systemic issues, not individual cases.

Despite these limitations, the study aims to provide robust, meaningful insights into the effectiveness of audit reports on the improvement of financial management in federal educational parastatals.

CHAPTER TWO: REVIEW OF RELATED LITERATURE

2.1 Introduction

This chapter reviews the literature relevant to the effectiveness of audit reports on the improvement of financial management in federal parastatals, with a focus on the educational system in Nigeria. The review is organized into conceptual framework and theoretical considerations. The conceptual framework covers the concept of audit and auditing, definitions, distinctions between financial audit and review service, types of auditors (financial accounting auditors, fraud and investigation auditors, forensic accounting and fraud examiners), auditors’ duties and the concept of audit expectation gaps (AEGs), giving an opinion on the fairness of financial statements, National Universities Commission, National Mathematical Centre, giving an opinion on the company’s ability to continue as a going concern, giving an opinion on the company’s internal control system, giving an opinion on the occurrence of fraud, the audit report, basic elements of an audit report, and report title. The chapter provides the theoretical and conceptual foundation for understanding how audit reports can improve financial management in federal parastatals.

2.2 Conceptual Framework

2.2.1 The Concept of Audit and Auditing

The concept of auditing has evolved significantly over time. Historically, auditing was primarily concerned with the detection of fraud and errors (the “detective” role). The auditor’s job was to find mistakes and irregularities. Over time, the role of auditing expanded to include the verification of financial statements and the expression of an opinion on whether they present a true and fair view (the “verification” role). More recently, the role of auditing has expanded further to include the evaluation of internal controls, risk management, and governance processes (the “assurance” and “consulting” roles). In the public sector, auditing also includes performance auditing (evaluating economy, efficiency, and effectiveness) and compliance auditing (evaluating adherence to laws and regulations) (Hayes, Dassen, Schilder, and Wallage, 2019; INTOSAI, 2020).

Auditing is a systematic, objective, and independent examination of evidence to provide assurance to stakeholders. The key characteristics of auditing are: (a) systematic – audits follow a structured methodology (planning, execution, reporting, follow-up), (b) objective – auditors must be unbiased and impartial, (c) independent – auditors must be free from influences that could compromise their judgment, (d) evidence-based – conclusions must be based on sufficient, appropriate audit evidence, (e) assurance-providing – the audit report provides assurance to stakeholders, and (f) communicative – findings and conclusions are communicated to relevant parties (Arens, Elder, and Beasley, 2017).

2.2.2 Defining Audit and Auditing

Audit: 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 and to ensure that financial transactions comply with relevant laws, regulations, and internal policies.

Auditing: The process of conducting an audit, including planning, execution, reporting, and follow-up.

Public Sector Auditing: The audit of government entities, with emphasis on accountability, transparency, and proper use of public funds. Public sector auditing includes financial audit, compliance audit, and performance audit (INTOSAI, 2020).

Internal Auditing: An independent, objective assurance and consulting activity within an organization designed to add value and improve operations, including evaluating risk management, control, and governance processes. Internal auditors report to the audit committee (IIA, 2017).

External Auditing: An independent examination of an organization’s financial statements by an external auditor (in the public sector, the Office of the Auditor-General of the Federation or its appointed representatives). External auditors report to the legislature (or shareholders in the private sector).

Forensic Auditing: A specialized branch of auditing focused on the detection, investigation, and prevention of fraud, financial crimes, and other irregularities, with the aim of producing evidence suitable for legal proceedings (Wells, 2017).

2.2.3 Distinctions between Financial Audit and a Review Service

A financial audit and a review service are different levels of assurance provided by independent accountants:

Feature	Financial Audit	Review Service
Level of Assurance	Reasonable assurance (high, but not absolute)	Limited assurance (lower than audit)
Procedures	Extensive: testing of internal controls, substantive testing of transactions, confirmations, physical inspection, analytical procedures	Limited: inquiry and analytical procedures only; no testing of controls or physical inspection
Opinion	“The financial statements present a true and fair view” (positive assurance)	“We are not aware of any material modifications that should be made” (negative assurance)
Cost	Higher	Lower
Legal Requirement	Required for public companies and public sector entities	Optional (often for internal use or lenders)
User	Investors, creditors, regulators, public	Management, lenders, internal users

For federal parastatals in Nigeria, a full financial audit (not a review) is required by the Constitution and the Audit Act (Hayes et al., 2019).

2.2.4 Financial Accounting Auditors, Fraud and Investigation Auditors and Forensic Accounting and Fraud Examinations

There are different types of auditors with different specializations:

Type	Focus	Skills	Output
Financial Accounting Auditors	Fairness of financial statements	Accounting, auditing standards, internal controls	Audit opinion on financial statements
Fraud and Investigation Auditors	Detection of fraud	Investigative skills, interviewing, document examination	Investigation report, evidence for management
Forensic Accounting and Fraud Examiners	Legal evidence for prosecution	Accounting, law, evidence collection, courtroom testimony	Expert report, expert witness testimony

In the public sector, the Office of the Auditor-General (OAuGF) primarily performs financial audits. However, the OAuGF may also conduct fraud investigations (often in collaboration with anti-corruption agencies like EFCC, ICPC). For complex fraud cases, the OAuGF may engage forensic accountants (Wells, 2017; Hayes et al., 2019).

2.2.5 Financial Auditors

Financial auditors (also called external auditors or statutory auditors) are independent professionals who examine an organization’s financial statements and express an opinion on whether they present a true and fair view. In the public sector, the Auditor-General is the financial auditor for all federal government entities. The Auditor-General may delegate the audit to private audit firms (under contract) but remains responsible for the audit opinion.

Duties of Financial Auditors:

• Plan and execute the audit in accordance with auditing standards (ISSAI for public sector).
• Obtain sufficient appropriate audit evidence.
• Evaluate internal controls over financial reporting.
• Identify instances of non-compliance with laws and regulations.
• Express an audit opinion (unqualified, qualified, adverse, disclaimer).
• Issue a management letter with recommendations for improvement.
• Report to the legislature (National Assembly) and the public (Arens et al., 2017).

2.2.6 Fraud and Investigation Auditors

Fraud and investigation auditors specialize in detecting and investigating fraud. They may be internal auditors (internal audit department), external auditors (if fraud is suspected during the audit), or investigators from anti-corruption agencies. Fraud auditors use investigative techniques: (a) document examination (forged signatures, altered documents), (b) data analytics (anomaly detection), (c) interviews (interrogation of suspects), (d) surveillance, and (e) forensic technology (computer forensics, email analysis). Fraud auditors produce investigation reports that may be used for disciplinary action or criminal prosecution (Wells, 2017).

2.2.7 Forensic Accounting and Fraud Examination

Forensic accounting is the application of accounting, auditing, and investigative skills to legal disputes. Forensic accountants are often hired to: (a) quantify economic damages (e.g., in litigation), (b) trace assets in divorce or fraud cases, (c) provide expert testimony in court, and (d) assist in fraud investigations. Fraud examination is a subset of forensic accounting focused specifically on fraud. Fraud examiners are certified (Certified Fraud Examiner, CFE) and specialize in: (a) fraud prevention (anti-fraud controls), (b) fraud detection (red flags, data analytics), and (c) fraud investigation (interviews, evidence collection) (Wells, 2017).

In the context of federal parastatals, forensic accountants may be engaged when complex fraud is suspected (e.g., ghost workers, procurement fraud, inflated contracts). The OAuGF may work with forensic accountants from anti-corruption agencies (EFCC, ICPC) or hire external forensic accounting firms.

2.2.8 Auditors’ Duties and the Concept of Audit Expectation Gaps (AEGs)

The Audit Expectation Gap (AEG) is the difference between what the public (and other stakeholders) expect from an audit and what auditors actually do. The expectation gap has two components:

Reasonableness Gap: The difference between what society expects from auditors and what auditors can reasonably be expected to accomplish (e.g., the public may expect auditors to detect all fraud, but audits are based on sampling and have inherent limitations).

Performance Gap: The difference between what auditors can reasonably accomplish and what they actually accomplish (e.g., auditors fail to detect fraud due to inadequate procedures or lack of professional skepticism).

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 public sector, the expectation gap is often wider because stakeholders may expect auditors to detect all corruption and inefficiency. Public sector auditors must manage expectations through: (a) clear communication of audit scope and limitations, (b) emphasis on the audit opinion (not a fraud detection guarantee), (c) timely reporting of findings, and (d) cooperation with anti-corruption agencies.

For federal educational parastatals, stakeholders (citizens, legislators, civil society) may expect the OAuGF to detect all financial irregularities. The OAuGF must educate stakeholders about the limitations of financial audits (e.g., sampling, reliance on management representations, collusion). The OAuGF may also conduct special audits (forensic audits) for fraud cases (Oyo-Ita, 2019).

2.2.9 Giving an Opinion on the Fairness of Financial Statements

The primary objective of a financial audit is to express an opinion on whether the financial statements present a true and fair view (in accordance with applicable accounting standards). The auditor’s opinion is based on the auditor’s assessment of material misstatements (errors or fraud). The opinion can be:

Unqualified (Clean) Opinion: The financial statements present a true and fair view in all material respects. This is the desired outcome.

Qualified Opinion: The financial statements present a true and fair view except for specific issues (e.g., a material misstatement in one area). The auditor describes the issue in the opinion paragraph.

Adverse Opinion: The financial statements do not present a true and fair view (i.e., there are material and pervasive misstatements). This is a very negative opinion.

Disclaimer of Opinion: The auditor is unable to obtain sufficient appropriate audit evidence to express an opinion (scope limitation). This may occur if management restricts access to records or if significant uncertainty exists (Hayes et al., 2019).

For federal parastatals, an unqualified opinion is expected. Qualified or adverse opinions indicate serious financial management weaknesses and may trigger PAC hearings, sanctions, or management changes.

2.2.10 National Universities Commission

The National Universities Commission (NUC) is a federal parastatal under the Federal Ministry of Education. The NUC was established by the NUC Act (Cap N81, Laws of the Federation of Nigeria, 2004). The NUC is responsible for: (a) regulating and accrediting university programmes in Nigeria, (b) setting academic standards, (c) approving the establishment of new universities, (d) allocating funding to federal universities, (e) monitoring university performance, and (f) advising the Federal Government on university education policy (NUC, 2022).

As a federal parastatal, the NUC is subject to the financial management and audit requirements of the federal government. The OAuGF audits the NUC’s financial statements annually. Audit reports on the NUC have highlighted issues such as: (a) delayed submission of financial statements, (b) inadequate documentation for expenditures, (c) procurement irregularities, and (d) weak internal controls over internally generated revenue (IGR) (Oyo-Ita, 2019).

2.2.11 National Mathematical Centre

The National Mathematical Centre (NMC) is a federal parastatal under the Federal Ministry of Education. The NMC was established by Decree No. 39 of 1988 (now NMC Act). The NMC is responsible for: (a) promoting mathematical sciences research, (b) organizing workshops, conferences, and training programs, (c) publishing research journals, (d) providing postgraduate scholarships, and (e) serving as a centre of excellence in mathematical sciences. The NMC is located in Abuja, with programmes across Nigeria (NMC, 2022).

As a federal parastatal, the NMC is subject to the financial management and audit requirements of the federal government. The OAuGF audits the NMC’s financial statements annually. Audit reports on the NMC have highlighted issues such as: (a) inadequate internal controls over cash, (b) lack of bank reconciliations, (c) unauthorized expenditures, and (d) poor record-keeping (Oyo-Ita, 2019).

2.3 Giving an Opinion on the Company’s Ability to Continue as a Going Concern

The going concern concept is a fundamental assumption in financial reporting: the entity is expected to continue operating for the foreseeable future (at least 12 months from the reporting date). If there is significant doubt about the entity’s ability to continue as a going concern, the financial statements must disclose this fact, and the auditor must modify the audit opinion.

The auditor evaluates the entity’s ability to continue as a going concern by considering: (a) financial indicators (recurring operating losses, negative cash flows, negative net assets, default on loans), (b) operational indicators (loss of key management, loss of major customers/suppliers, labour unrest), and (c) other indicators (legal proceedings, regulatory actions, natural disasters).

If the auditor concludes that there is material uncertainty about the entity’s ability to continue as a going concern, the auditor must:

• Include an emphasis of matter paragraph in the audit report (if the uncertainty is adequately disclosed in the financial statements).
• Modify the audit opinion (if the uncertainty is not adequately disclosed).

For federal parastatals, going concern issues may arise if the parastatal is heavily dependent on government funding and government funding is delayed or reduced. However, most federal parastatals are considered going concerns due to the expectation of continued government funding (Hayes et al., 2019; Arens et al., 2017).

2.3.1 Giving an Opinion on the Company’s Internal Control System

Under modern auditing standards (e.g., ISA 315), auditors are required to understand the entity’s internal control system and assess control risk. In a financial statement audit, the auditor does not express a separate opinion on the effectiveness of internal controls (except in integrated audits for public companies). However, the auditor is required to communicate “significant deficiencies” and “material weaknesses” in internal controls to management and the audit committee (in a management letter).

Significant Deficiency: A deficiency (or combination of deficiencies) in internal control that is less severe than a material weakness yet important enough to merit attention by those charged with governance.

Material Weakness: A deficiency (or combination of deficiencies) in internal control such that there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected on a timely basis.

In the public sector, the Auditor-General often issues a separate report on internal controls (part of the management letter or a separate report). The Auditor-General’s office also assesses internal controls as part of the financial audit. Weak internal controls are a common audit finding for federal parastatals (e.g., lack of segregation of duties, inadequate documentation, weak access controls) (INTOSAI, 2020; Okafor and Udeh, 2020).

2.3.2 Giving an Opinion on the Occurrence of Fraud

The auditor is responsible for obtaining reasonable assurance that the financial statements are free from material misstatement, whether caused by error or fraud. However, the auditor is not responsible for preventing fraud or detecting all fraud (the expectation gap). The auditor’s responsibilities for fraud include:

• Assess the risk of material misstatement due to fraud.
• Design and perform audit procedures to respond to assessed fraud risks.
• Test journal entries and other adjustments for evidence of possible misstatement due to fraud.
• Evaluate management’s override of controls.
• Communicate any fraud or suspected fraud to management and the audit committee (and to regulatory authorities if required).

If the auditor detects fraud (or suspects fraud), the auditor must:

• Consider the implications for the audit (additional procedures, withdrawal from the engagement).
• Communicate with management and the audit committee.
• Consider whether to report the fraud to regulatory authorities (e.g., anti-corruption agencies).
• Modify the audit opinion if the fraud is not adequately reflected in the financial statements.

In the public sector, the Auditor-General is required to report fraud (or suspected fraud) to the Public Accounts Committee (PAC) and to anti-corruption agencies (EFCC, ICPC). The OAuGF may also conduct special fraud investigations (forensic audits) (Wells, 2017; Hayes et al., 2019).

2.3.3 Audit Report

The audit report is the formal output of the audit process, containing the auditor’s opinion, findings, conclusions, and recommendations. The audit report is addressed to the relevant authority (e.g., management, board, audit committee, legislature). In the public sector, the audit report is a public document (available on the OAuGF website). The audit report is the primary means of communication between the auditor and stakeholders.

Purpose of the Audit Report:

• To communicate the auditor’s opinion on the financial statements.
• To highlight significant issues (material misstatements, non-compliance, internal control weaknesses).
• To provide recommendations for improvement.
• To hold management accountable for financial management.
• To inform legislative oversight (Public Accounts Committee hearings).

2.3.4 Basic Elements of an Audit Report

Under ISA 700 (and ISSAI 1700), an unqualified audit report (unmodified opinion) includes the following basic elements:

1. Title: “Independent Auditor’s Report”
2. Addressee: To the shareholders (private sector) or the Legislature (public sector) or the Governing Council (parastatal).
3. Introductory Paragraph: Identifies the financial statements audited, the date and period covered, and management’s responsibility for the financial statements.
4. Management’s Responsibility: Describes management’s responsibility for preparing the financial statements in accordance with applicable accounting standards and for designing internal controls.
5. Auditor’s Responsibility: Describes the auditor’s responsibility to express an opinion based on the audit, conducted in accordance with auditing standards.
6. Scope Paragraph: Describes the audit procedures (testing of controls, substantive testing, confirmations, etc.) and states that the audit provides reasonable assurance.
7. Opinion Paragraph: Expresses the auditor’s opinion on whether the financial statements present a true and fair view (unqualified, qualified, adverse, disclaimer).
8. Basis for Opinion Paragraph (for modified opinions): Explains the reasons for a qualified, adverse, or disclaimer opinion.
9. Other Reporting Responsibilities: Describes any other reporting responsibilities (e.g., reporting on internal controls, compliance).
10. Signature of the Auditor: The auditor’s name (or audit firm).
11. Date of the Audit Report: The date the auditor completed the audit procedures.
12. Auditor’s Address: The auditor’s location.
13. Auditor’s Registration Number (where required) (Hayes et al., 2019; Arens et al., 2017).

In the public sector, the audit report may also include:

• A report on internal controls (separate or within the management letter).
• A report on compliance with laws and regulations.
• A report on performance (value for money) (INTOSAI, 2020).

2.3.5 Report Title

The title of the audit report identifies the document as an independent auditor’s report, distinguishing it from reports prepared by management or internal auditors. The title typically is “Independent Auditor’s Report” (for external audit) or “Report of the Auditor-General” (for public sector audit). In the Nigerian public sector, the report is titled “Report of the Auditor-General of the Federation on the Financial Statements of [Name of Parastatal] for the Year Ended [Date]” (OAuGF, 2022).

The title clarifies:

• The auditor is independent (not management or internal audit).
• The report is a formal audit opinion (not a review or compilation).
• The report is addressed to the appropriate authority (National Assembly, Governing Council).
