THE INFLUENCE OF STATUTORY AUDIT ON SMES GROWTH AND SURVIVAL IN NIGERIA

CHAPTER ONE: INTRODUCTION

1.1 Background of the Study

Statutory audit refers to a legally mandated independent examination of a company’s financial statements and accounting records by an external auditor to determine whether the financial statements present a true and fair view in accordance with applicable financial reporting standards and legal requirements. Unlike voluntary audits (which companies choose to conduct for internal purposes), statutory audits are required by law for certain categories of companies based on size, ownership structure, or industry. The primary purpose of a statutory audit is to provide assurance to stakeholders—investors, creditors, regulators, and the public—that the financial statements are reliable and free from material misstatement (IFAC, 2018). (IFAC, 2018)

Small and Medium Enterprises (SMEs) are the backbone of the Nigerian economy. The Small and Medium Enterprises Development Agency of Nigeria (SMEDAN) classifies SMEs as enterprises with 10-199 employees and annual turnover between ₦5 million and less than ₦500 million (with micro enterprises having 1-9 employees and turnover below ₦5 million). SMEs constitute over 90% of all businesses in Nigeria, employ approximately 60% of the workforce, and contribute about 48% to the national GDP. They operate across all sectors: manufacturing, trade, services, agriculture, construction, and information technology. Despite their numerical dominance and economic importance, SMEs face numerous challenges including limited access to finance, poor infrastructure, multiple taxation, regulatory burdens, and high failure rates (SMEDAN, 2020). (SMEDAN, 2020)

The relationship between statutory audit and SME growth and survival is a subject of ongoing debate. On one hand, proponents argue that statutory audits provide critical benefits for SMEs. First, credibility: audited financial statements enhance the credibility of SME financial information, enabling access to bank loans, trade credit, and government contracts. Second, internal control improvement: auditors identify weaknesses in internal controls and make recommendations that strengthen SME operations. Third, fraud detection and deterrence: the threat of audit deters fraud, and audits can detect existing fraud. Fourth, management accountability: audits hold SME owners/managers accountable for financial reporting accuracy. Fifth, tax compliance: audited financial statements facilitate accurate tax filing and reduce the risk of tax penalties (Blackburn, Hart, and Wainwright, 2013). (Blackburn et al., 2013)

On the other hand, critics argue that statutory audits impose excessive costs on SMEs. Direct costs include auditor fees, management time spent preparing for the audit, and disruption of normal operations. Indirect costs include the cost of implementing audit recommendations (e.g., upgrading internal controls) and the potential for “audit fatigue” (excessive focus on compliance at the expense of business development). For small SMEs with limited resources, audit costs may exceed the benefits. Furthermore, many SME owners and managers may not understand audit reports or may not use them for decision-making, rendering the audit value irrelevant. Some argue that the cost of statutory audit is a barrier to SME formalization and growth (Carey, 2015). (Carey, 2015)

The legal framework for statutory audit in Nigeria is provided by the Companies and Allied Matters Act (CAMA) 2020. CAMA 2020 requires that all companies registered in Nigeria (including SMEs) appoint an external auditor and have their financial statements audited annually. However, CAMA 2020 introduced a tiered audit exemption: “small companies” (defined by turnover, assets, and employee thresholds) may be exempt from statutory audit. The specific thresholds are prescribed by the Financial Reporting Council (FRC) of Nigeria. This tiered approach recognizes that the costs of audit may outweigh the benefits for very small enterprises, while larger SMEs (approaching medium status) may benefit from audit (Federal Republic of Nigeria, 2020). (Federal Republic of Nigeria, 2020)

The FRC of Nigeria, under the FRC Act (2011) and the Nigerian Code of Corporate Governance (2018), has issued guidance on audit requirements for SMEs. The FRC’s “Tiered Reporting Framework” classifies entities into tiers based on public interest and size. Tier 1 entities (public interest entities, including public companies and large enterprises) must apply full IFRS and undergo full statutory audit. Tier 2 entities (medium-sized enterprises, including larger SMEs) must apply IFRS for SMEs and undergo statutory audit. Tier 3 entities (small enterprises) may apply simplified reporting standards and may be exempt from statutory audit (FRC, 2018). (FRC, 2018)

The growth of SMEs can be measured through several indicators: revenue growth (increase in annual turnover), employment growth (increase in number of employees), asset growth (increase in fixed assets), market expansion (new customers, new geographic markets), and profitability growth (increase in net profit margins). Survival is typically measured as continued operation over a specified period (e.g., 3, 5, or 10 years). SME failure rates in Nigeria are high: estimates suggest that 50-70% of SMEs fail within the first five years of operation. Factors contributing to failure include undercapitalization, poor financial management, lack of access to credit, and weak internal controls. Statutory audit may address some of these factors, but its influence on survival is not well documented (Abor and Quartey, 2010). (Abor and Quartey, 2010)

Several mechanisms explain how statutory audit might influence SME growth and survival. Financial mechanism: audited financial statements improve SME access to bank loans. Banks rely on audited financial statements to assess creditworthiness, determine loan amounts and interest rates, and monitor loan compliance. SMEs with audited statements may receive larger loans, lower interest rates, and longer repayment periods, enabling investment in growth. Operational mechanism: audit recommendations (management letters) identify internal control weaknesses and operational inefficiencies, enabling management to improve processes, reduce waste, and increase profitability. Governance mechanism: the audit process imposes discipline on SME owners/managers, reducing the likelihood of fraud, asset misappropriation, and financial mismanagement (Carey, 2015). (Carey, 2015)

In Nigeria, access to finance is the single most cited constraint to SME growth. Banks require financial statements (preferably audited) for loan applications. However, many Nigerian SMEs do not maintain complete accounting records, and even fewer have audited financial statements. Okafor and Amalu (2018) found that only 28% of Nigerian SMEs maintained complete accounting records, and only 12% had ever had a statutory audit. Without audited statements, SMEs are effectively excluded from formal credit, forcing them to rely on expensive informal sources (money lenders, contributions, family). Statutory audit could be a gateway to finance, but only if the costs of audit are not prohibitive (Okafor and Amalu, 2018). (Okafor and Amalu, 2018)

The costs of statutory audit for SMEs include: (1) auditor fees: typically based on audit hours and complexity, ranging from ₦200,000 to over ₦2 million annually; (2) internal staff time: preparing for the audit, responding to auditor queries, and implementing recommendations; (3) disruption: auditors need access to records, people, and premises, disrupting normal operations; (4) recommendation implementation costs: auditors may recommend upgrading accounting software, hiring additional staff, or strengthening controls; and (5) indirect costs: potential liability if audit fails to detect fraud, and potential for “audit fatigue” (Collis, Jarvis, and Page, 2004). (Collis et al., 2004)

For micro and small enterprises, audit costs may exceed the benefits. An SME with turnover of ₦10 million and profit of ₦1 million cannot afford an audit costing ₦500,000 (50% of profit). For such enterprises, exemption from statutory audit (as provided under CAMA 2020) is economically rational. For larger SMEs (e.g., turnover of ₦200 million, profit of ₦20 million), audit costs of ₦1 million (5% of profit) may be justifiable if the audit enables access to ₦50 million in bank loans. The optimal audit threshold (the size at which benefits exceed costs) is an empirical question that this study addresses (Carey, 2015). (Carey, 2015)

The quality of statutory audits for SMEs is also a concern. Big Four audit firms (Deloitte, PwC, EY, KPMG) focus on large corporate clients; SMEs are typically audited by small and medium audit firms (often sole practitioners). The quality of these audits varies: some are rigorous and add value; others are perfunctory (focused on ticking boxes rather than substantive testing). The FRC’s audit quality assurance reviews have found deficiencies in audits of SME clients, including inadequate documentation, insufficient testing, and failure to identify material misstatements (FRC, 2020). (FRC, 2020)

The COVID-19 pandemic has created new challenges and opportunities for statutory audit and SME survival. During the pandemic, many SMEs faced revenue declines, cash flow crises, and closure threats. Audited financial statements were required to access government relief funds (e.g., CBN’s Targeted Credit Facility). SMEs with audited statements were better positioned to apply for relief. Conversely, the pandemic also increased audit costs (remote audit procedures, travel restrictions, health protocols) and some SMEs chose not to renew audit engagements to save costs. The pandemic thus created a natural experiment to examine the value of audit for SME survival (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

Several theories explain the relationship between statutory audit and SME growth and survival. Agency theory (Jensen and Meckling, 1976) posits that audit reduces information asymmetry between SME owners (who may also be managers) and external stakeholders (banks, creditors). By providing credible financial information, audit enables stakeholders to make informed decisions, reducing the cost of capital and facilitating growth. Signaling theory (Spence, 1973) suggests that SMEs that voluntarily undergo audit (or comply with statutory requirements) signal their quality and reliability to banks, customers, and suppliers, differentiating themselves from non-audited competitors. (Jensen and Meckling, 1976; Spence, 1973)

Resource-based view (Barney, 1991) suggests that audit can be a source of competitive advantage if it enables the SME to access resources (finance, contracts) that are unavailable to non-audited SMEs. The audit process itself may build organizational capabilities (improved internal controls, financial management skills) that enhance SME performance. Institutional theory (DiMaggio and Powell, 1983) suggests that SMEs adopt statutory audit not only for its direct benefits but also because of coercive pressures (legal requirements), mimetic pressures (copying successful firms), and normative pressures (professional norms). The influence of audit on growth and survival may be mediated by the SME’s reasons for adopting audit (voluntary vs. compliant). (Barney, 1991; DiMaggio and Powell, 1983)

In Nigeria, there is a significant gap in empirical research on the influence of statutory audit on SME growth and survival. While numerous studies have examined the benefits and costs of audit for SMEs in developed economies (UK, Europe, Australia), very few studies have been conducted in Nigeria or other West African countries. Nigerian SMEs operate in a different environment: weaker regulatory enforcement, higher corruption, limited access to finance, different cultural norms, and different SME support structures. Findings from developed economies may not generalize to Nigeria. This study addresses this gap (Adeyemi and Ogundipe, 2019). (Adeyemi and Ogundipe, 2019)

The practical implications of this study are substantial. If statutory audit is found to have a positive influence on SME growth and survival, then policymakers should retain or expand audit requirements for SMEs, and SME support programs (e.g., SMEDAN, BOI) should subsidize audit costs for small SMEs. If statutory audit has no influence or a negative influence, then audit exemptions should be expanded, and resources should be redirected to other SME support mechanisms (e.g., financial literacy training, accounting software subsidies). This study provides evidence for evidence-based policy (Collis et al., 2004). (Collis et al., 2004)

Finally, the influence of statutory audit on SME survival is a matter of public interest. SME failures result in job losses, lost investment, reduced tax revenue, and negative economic impacts. If statutory audit can reduce SME failure rates by even a few percentage points, the social benefits (preserved jobs, continued tax revenue) may outweigh the private costs. Conversely, if audit does not reduce failure rates, then the resources spent on mandatory audit for SMEs are wasted. This study provides evidence to inform this societal trade-off (Blackburn et al., 2013). (Blackburn et al., 2013)

1.2 Statement of the Problem

Despite the legal requirement for statutory audit for many SMEs under CAMA 2020, and despite theoretical arguments that audit should enhance SME growth and survival, there is limited empirical evidence in Nigeria on whether statutory audit actually achieves these benefits. This gap creates several interrelated problems for policymakers, SME owners, lenders, and other stakeholders.

First, the cost-benefit trade-off of statutory audit for SMEs is unknown. Statutory audits impose direct costs (auditor fees) and indirect costs (management time, disruption, recommendation implementation). If the benefits of audit (access to finance, improved internal controls, fraud reduction) do not outweigh the costs, then the statutory requirement may be harming SMEs rather than helping them. In developed economies, research suggests that audit benefits exceed costs for SMEs above a certain size threshold (e.g., turnover > £10 million in the UK), but below that threshold, costs may exceed benefits. The Nigerian threshold is unknown. Policymakers cannot set optimal audit exemption thresholds without evidence (Collis et al., 2004). (Collis et al., 2004)

Second, the relationship between statutory audit and access to finance has not been quantified in Nigeria. Banks claim that they require audited financial statements for loan applications. However, it is unknown whether SMEs with audited statements actually have higher loan approval rates, larger loan amounts, or lower interest rates than SMEs without audited statements. Without this evidence, SME owners cannot assess whether the investment in audit will pay off in terms of improved access to finance. Similarly, banks cannot quantify the value of audit in their credit risk models (Abor and Quartey, 2010). (Abor and Quartey, 2010)

Third, the influence of statutory audit on SME survival has not been studied in Nigeria. High SME failure rates (50-70% within five years) impose economic costs. If statutory audit reduces failure rates, then policies that promote audit (e.g., subsidized audits, expanded mandatory audit) could be justified on social welfare grounds. However, if audit does not reduce failure rates, then the compliance costs are wasted. No Nigerian study has tracked a cohort of SMEs over time to compare survival rates of audited vs. non-audited firms (Blackburn et al., 2013). (Blackburn et al., 2013)

Fourth, the quality of statutory audits for SMEs is questionable. The FRC’s audit quality reviews have found deficiencies in SME audits. However, there is no data on whether these deficiencies translate into lower audit benefits. Do SMEs that receive low-quality audits (e.g., perfunctory compliance checks) have different outcomes than SMEs that receive high-quality audits (e.g., substantive testing, management letter recommendations)? Without this evidence, the FRC cannot target its quality assurance resources effectively (FRC, 2020). (FRC, 2020)

Fifth, SME owners’ perceptions of statutory audit are not well understood. Many SME owners may not understand what auditors do, may not read audit reports, or may not implement audit recommendations. If owners perceive audit as a useless compliance burden, they will not act on audit findings, and the potential benefits will not be realized. Conversely, if owners perceive audit as valuable, they will engage actively with auditors. Understanding perceptions is essential for designing SME education and support programs (Carey, 2015). (Carey, 2015)

Sixth, the CAMA 2020 audit exemption thresholds may be mis-calibrated. CAMA 2020 exempts “small companies” from statutory audit but delegates threshold definition to the FRC. Are the current thresholds (based on turnover, assets, employees) appropriate? Are there SMEs below the threshold that would benefit from audit (and should be encouraged to audit voluntarily)? Are there SMEs above the threshold for which audit costs exceed benefits (and should be exempted)? Without evidence on the size-benefit relationship, the thresholds are arbitrary (Federal Republic of Nigeria, 2020). (Federal Republic of Nigeria, 2020)

Seventh, the COVID-19 pandemic has disrupted audit services and SME operations, but the impact on audit value is unknown. During the pandemic, many SMEs deferred or canceled audits to save costs. Did this affect their access to relief funds? Did it affect their survival? The pandemic provides a natural experiment to examine whether audit matters in a crisis. However, no Nigerian study has analyzed pandemic-era data (Ogunyemi and Adewale, 2021). (Ogunyemi and Adewale, 2021)

Eighth, there is a significant gap in empirical research on statutory audit and SMEs in Nigeria. Most existing studies have been conducted in developed economies (UK, Europe, Australia, Canada). Nigerian SMEs operate in a different environment: weaker regulatory enforcement, higher corruption, limited access to finance, different cultural norms, and different SME support structures. Findings from developed economies may not generalize to Nigeria. This study addresses this gap (Adeyemi and Ogundipe, 2019). (Adeyemi and Ogundipe, 2019)

Therefore, the central problem this study seeks to address can be stated as: Despite the statutory requirement for audit for many SMEs in Nigeria and the theoretical importance of audit for SME growth and survival, there is limited empirical evidence on whether statutory audit actually achieves these benefits. The cost-benefit trade-off is unknown; the relationship with access to finance is unquantified; the influence on survival has not been studied; audit quality issues are unexamined; owner perceptions are not understood; exemption thresholds may be mis-calibrated; and the pandemic’s impact is unknown. This study addresses these gaps by empirically examining the influence of statutory audit on SME growth and survival in Nigeria.

1.3 Aim of the Study

The aim of this study is to critically examine the influence of statutory audit on the growth and survival of Small and Medium Enterprises (SMEs) in Nigeria, with a view to determining the benefits (access to finance, internal control improvement, fraud reduction) and costs of statutory audit for SMEs, assessing the relationship between audit status and SME outcomes (revenue growth, employment growth, survival), and providing evidence-based recommendations for audit policy and SME support programs.

1.4 Objectives of the Study

The specific objectives of this study are to:

1. Assess the extent of statutory audit compliance among SMEs in Nigeria, including the characteristics of SMEs that comply (size, industry, location, ownership structure).
2. Determine the perceived benefits (access to finance, internal control improvement, fraud reduction, credibility enhancement) and costs (auditor fees, management time, disruption) of statutory audit from the perspective of SME owners/managers.
3. Examine the relationship between statutory audit and SME access to finance, including loan application success rates, loan amounts, interest rates, and loan terms.
4. Compare the growth (revenue growth, employment growth, asset growth) of audited SMEs versus non-audited SMEs over a specified period.
5. Determine the relationship between statutory audit and SME survival, comparing survival rates of audited versus non-audited SMEs over 3, 5, and 10-year horizons.
6. Examine the relationship between audit quality (audit firm size, auditor experience, management letter recommendations) and SME outcomes.
7. Assess SME owner/managers’ perceptions of the statutory audit requirement (value vs. compliance burden).
8. Propose evidence-based recommendations for audit policy (exemption thresholds, subsidized audits, quality assurance) and SME support programs.

1.5 Research Questions

The following research questions guide this study:

1. What is the extent of statutory audit compliance among SMEs in Nigeria, and what characteristics are associated with compliance?
2. What are the perceived benefits and costs of statutory audit from the perspective of SME owners/managers?
3. What is the relationship between statutory audit and SME access to finance (loan success rates, amounts, interest rates)?
4. Is there a significant difference in growth (revenue, employment, assets) between audited SMEs and non-audited SMEs?
5. Is there a significant difference in survival rates between audited SMEs and non-audited SMEs?
6. Does audit quality (firm size, auditor experience, management letter recommendations) influence SME outcomes?
7. How do SME owners/managers perceive the statutory audit requirement: as a value-adding tool or a compliance burden?
8. What policy recommendations can be proposed based on the findings?

• H₁₈: SMEs that voluntarily underwent audit have significantly higher growth and survival than those subject to mandatory audit.

1.7 Significance of the Study

This study holds significance for multiple stakeholders as follows:

For SME Owners and Managers:
The study provides empirical evidence on whether statutory audit is worth the cost. SME owners can use this evidence to decide whether to comply with audit requirements (if mandatory) or voluntarily undergo audit (if exempt). The study also identifies which benefits (access to finance, internal controls, fraud reduction) are most valuable, enabling owners to focus audit recommendations accordingly.

For Banks and Other Lenders:
The study provides evidence on the relationship between audit status and SME creditworthiness. Banks can use this evidence to refine their lending policies: should audited financial statements be required for all SME loans, or only above certain thresholds? Should banks offer lower interest rates to audited SMEs? The study also provides evidence on the reliability of audited vs. unaudited financial statements for credit decisions.

For Policymakers (National Assembly, FRC, CBN, SMEDAN):
The study provides evidence to inform audit policy for SMEs. Should the current audit exemption thresholds be increased, decreased, or maintained? Should the government subsidize audits for small SMEs? Should there be tiered audit requirements (full audit, review, compilation) based on SME size? The study answers these questions.

For the Financial Reporting Council (FRC) of Nigeria:
The FRC is responsible for setting audit requirements and monitoring audit quality. The study provides evidence on the value of audit for SMEs, which can inform the FRC’s tiered reporting framework. The study also identifies audit quality issues (e.g., deficiencies in SME audits) that the FRC should address through guidance, training, and enforcement.

For the Small and Medium Enterprises Development Agency of Nigeria (SMEDAN):
SMEDAN is responsible for SME development programs. The study provides evidence on whether audit support should be included in SME development programs (e.g., subsidized audit vouchers, audit training, matching grants for audit costs). The study also identifies the types of SMEs (by size, industry, location) that benefit most from audit, enabling targeted support.

For the Central Bank of Nigeria (CBN) and Bank of Industry (BOI):
The CBN and BOI provide subsidized loans to SMEs through various programs (e.g., Targeted Credit Facility, SME Credit Guarantee Scheme). The study provides evidence on whether audited financial statements should be required for these programs, and whether loan amounts should be higher for audited SMEs.

For Audit Firms and Practitioners:
The study provides evidence on the value that SMEs derive from audit, enabling audit firms to better market their services to SME clients. The study also identifies SME owner perceptions of audit (e.g., perceived as useless compliance burden), which audit firms can address through better communication and value-added services (e.g., management letters with actionable recommendations).

For Professional Accounting Bodies (ICAN, ACCA, ANAN):
The study provides evidence on the role of audit in SME growth and survival, which can inform professional development programs for auditors serving SME clients. The study also identifies skills gaps (e.g., communicating audit findings to non-financial SME owners) that professional bodies can address through training and CPD.

For Academics and Researchers:
This study contributes to the literature on SME auditing in several ways. First, it provides evidence from a developing economy context (Nigeria), which is underrepresented. Second, it examines both growth and survival outcomes. Third, it uses multiple methods (survey, interviews, archival data). Fourth, it tests multiple theoretical frameworks (agency theory, signaling theory, resource-based view, institutional theory). The study provides a foundation for future research in other African countries and emerging markets.

For the Nigerian Economy:
SMEs are the engine of the Nigerian economy. If statutory audit enhances SME growth and survival, then policies that promote audit will have positive economic impacts: more jobs, higher tax revenue, increased innovation, and reduced poverty. Conversely, if audit does not benefit SMEs, then regulatory burden should be reduced, freeing resources for other SME support mechanisms. The study provides evidence for evidence-based economic policy.

1.8 Scope of the Study

The scope of this study is defined by the following parameters:

Content Scope: The study focuses on the influence of statutory audit on SME growth and survival. Specifically, it examines: (1) compliance with statutory audit requirements; (2) perceived benefits and costs of audit; (3) relationship between audit status and access to finance; (4) relationship between audit status and growth (revenue, employment, assets); (5) relationship between audit status and survival; (6) influence of audit quality on outcomes; and (7) SME owner perceptions. The study does not examine voluntary audits (where not legally required), internal audits, or non-audit assurance services (e.g., agreed-upon procedures, compilation).

Organizational Scope: The study focuses on Small and Medium Enterprises (SMEs) as defined by SMEDAN: small enterprises (10-49 employees, annual turnover ₦5 million – ₦50 million) and medium enterprises (50-199 employees, annual turnover ₦50 million – ₦500 million). The study excludes micro enterprises (1-9 employees, turnover < ₦5 million) because most are exempt from statutory audit. The study also excludes large enterprises (>200 employees) and public companies.

Industry Scope: The study includes SMEs across all sectors: manufacturing, trade (wholesale/retail), services (professional, technical, hospitality), agriculture, construction, and information technology. This diversity enables comparison across sectors.

Geographic Scope: The study is conducted in Lagos State, Ogun State, the Federal Capital Territory (Abuja), and Kano State, representing the South-West, North-Central, and North-West geopolitical zones. These states contain the highest concentration of SMEs in Nigeria. Findings may be generalizable to other Nigerian states but caution is warranted.

Time Scope: The study covers a five-year period (2019-2023), enabling measurement of growth trends and five-year survival. The period includes the COVID-19 pandemic (2020-2021), enabling examination of audit’s role in crisis survival. Data collection includes cross-sectional surveys (current perceptions) and retrospective questions about past outcomes.

Theoretical Scope: The study is grounded in agency theory, signaling theory, resource-based view, and institutional theory. These theories provide the conceptual lens for understanding the mechanisms through which audit influences SME outcomes.

CHAPTER TWO: LITERATURE REVIEW

2.1 Introduction

This chapter presents a comprehensive review of literature relevant to the influence of statutory audit on Small and Medium Enterprises (SMEs) growth and survival in Nigeria. The review is organized into five main sections. First, the conceptual framework section defines and explains the key constructs: statutory audit, SMEs, growth, survival, and the mechanisms through which audit may influence SME outcomes. Second, the theoretical framework section examines the theories that underpin the relationship between audit and SME performance, including agency theory, signaling theory, the resource-based view, institutional theory, and the cost-benefit theory. Third, the empirical review section synthesizes findings from previous studies on the relationship between audit and SME outcomes in developed economies and in developing economies. Fourth, the regulatory framework section examines the Nigerian context, including CAMA 2020, FRC requirements, and SME audit exemption thresholds. Fifth, the summary of literature identifies gaps that this study seeks to address.

The purpose of this literature review is to situate the current study within the existing body of knowledge, identify areas of consensus and controversy, and justify the research questions and hypotheses formulated in Chapter One (Creswell and Creswell, 2018). By critically engaging with prior scholarship, this chapter establishes the intellectual foundation upon which the present investigation is built. (Creswell and Creswell, 2018)

2.2 Conceptual Framework

2.2.1 The Concept of Statutory Audit

Statutory audit refers to a legally mandated independent examination of a company’s financial statements and accounting records by an external auditor to determine whether the financial statements present a true and fair view in accordance with applicable financial reporting standards and legal requirements. The International Federation of Accountants (IFAC, 2018) defines an audit as “a systematic process of objectively obtaining and evaluating evidence regarding assertions about economic actions and events to ascertain the degree of correspondence between those assertions and established criteria and communicating the results to interested users.” Statutory audit is distinguished from voluntary audit (which companies choose to conduct for internal purposes) and internal audit (conducted by employees of the organization). (IFAC, 2018)

The statutory audit requirement for SMEs varies across jurisdictions. In many countries, small companies are exempt from statutory audit based on size thresholds (e.g., turnover, assets, employees). The rationale for exemption is that the costs of audit for very small companies may outweigh the benefits. In the European Union, the Audit Directive exempts “small undertakings” from mandatory audit. In the United Kingdom, companies below the audit exemption threshold (turnover ≤ £10.2 million, assets ≤ £5.1 million, employees ≤ 50) may claim exemption. In Nigeria, the Companies and Allied Matters Act (CAMA) 2020 exempts “small companies” from statutory audit, with thresholds to be prescribed by the Financial Reporting Council (FRC) (Collis, Jarvis, and Page, 2004). (Collis et al., 2004; Federal Republic of Nigeria, 2020)

The statutory audit process for SMEs involves several stages: (1) engagement acceptance: auditor assesses whether they are independent and have the competence to perform the audit; (2) risk assessment: auditor understands the SME’s business, internal controls, and fraud risks; (3) testing: auditor tests transactions and balances to gather evidence; (4) evaluation: auditor evaluates whether financial statements are fairly presented; (5) reporting: auditor issues an opinion (unqualified, qualified, adverse, or disclaimer); and (6) management letter: auditor communicates internal control weaknesses and recommendations to management (IFAC, 2018). (IFAC, 2018)

2.2.2 The Concept of Small and Medium Enterprises (SMEs)

Small and Medium Enterprises (SMEs) are businesses that operate on a smaller scale than large corporations in terms of employment, assets, and annual turnover. Definitions vary by country and regulatory agency. In Nigeria, the Small and Medium Enterprises Development Agency of Nigeria (SMEDAN) provides the official classification (SMEDAN, 2020). (SMEDAN, 2020)

Enterprise Category	Employment	Annual Turnover	Assets (excluding land/buildings)
Micro Enterprise	1-9 employees	Less than ₦5 million	Less than ₦5 million
Small Enterprise	10-49 employees	₦5 million – ₦50 million	₦5 million – ₦50 million
Medium Enterprise	50-199 employees	₦50 million – ₦500 million	₦50 million – ₦500 million

For the purposes of this study, “SMEs” encompasses small and medium enterprises as defined by SMEDAN. Micro enterprises are excluded because most are exempt from statutory audit under CAMA 2020.

SMEs possess several qualitative characteristics that distinguish them from large corporations. Owner-management: the owner is typically the manager, making most strategic and operational decisions. Limited specialization: the owner and few employees perform multiple functions (production, marketing, finance, administration). Limited access to formal finance: SMEs rely primarily on owner savings, family contributions, and informal sources rather than bank loans. Simple management systems: formal strategic plans, budgets, and accounting systems are often absent. High vulnerability: SMEs are more vulnerable to economic shocks, competition, and management deficiencies than large corporations (Abor and Quartey, 2010). (Abor and Quartey, 2010)

2.2.3 The Concept of SME Growth

SME growth refers to the increase in the size, scale, or scope of an SME’s operations over time. Growth is a key indicator of SME success and is associated with job creation, wealth creation, and economic development. Growth can be measured using several indicators (Delmar, Davidsson, and Gartner, 2003). (Delmar et al., 2003)

Revenue growth: the percentage increase in annual turnover (sales). Revenue growth indicates increasing customer demand, market share expansion, and successful sales strategies. Employment growth: the percentage increase in number of employees. Employment growth indicates job creation and is a key policy objective. Asset growth: the percentage increase in total assets (property, plant, equipment, inventory, receivables). Asset growth indicates investment in productive capacity. Profitability growth: the percentage increase in net profit. Profitability growth indicates improving efficiency and pricing power. Market expansion: entry into new geographic markets or new customer segments.

For SMEs, growth is often not linear. SMEs may experience periods of rapid growth followed by consolidation. Some SMEs choose not to grow (e.g., lifestyle businesses). However, for policy purposes, growth is generally viewed as desirable. This study examines the influence of statutory audit on revenue growth, employment growth, and asset growth (Delmar et al., 2003). (Delmar et al., 2003)

2.2.4 The Concept of SME Survival

SME survival refers to the continued operation of an SME over a specified period. The opposite of survival is failure (cessation of operations). SME failure rates are high globally, with estimates suggesting that 50-70% of SMEs fail within the first five years of operation. In Nigeria, failure rates are similarly high. Survival is typically measured as the percentage of SMEs still operating after 3, 5, or 10 years (Abor and Quartey, 2010). (Abor and Quartey, 2010)

Factors associated with SME survival include: adequate capitalization (sufficient owner equity), access to finance (bank loans, trade credit), effective financial management (record keeping, cash flow management), strong internal controls, competent management (skills, experience), market conditions (demand, competition), and regulatory environment (taxation, compliance burden). Statutory audit may influence survival by improving financial management, internal controls, and access to finance (Blackburn, Hart, and Wainwright, 2013). (Blackburn et al., 2013)

2.2.5 Mechanisms Through Which Statutory Audit May Influence SME Growth and Survival

Several mechanisms explain how statutory audit could influence SME outcomes (Carey, 2015; Collis et al., 2004). (Carey, 2015; Collis et al., 2004)

Financial Mechanism (Access to Finance): Audited financial statements enhance the credibility of SME financial information. Banks and other lenders rely on audited statements to assess creditworthiness. SMEs with audited statements may have higher loan approval rates, larger loan amounts, lower interest rates, and longer repayment periods. Improved access to finance enables SMEs to invest in growth (new equipment, inventory, marketing, hiring). Conversely, SMEs without audited statements may be excluded from formal credit.

Operational Mechanism (Internal Control Improvement): During the audit, auditors identify internal control weaknesses and make recommendations in the management letter. SMEs that implement these recommendations strengthen their internal controls, reducing the risk of error, fraud, and inefficiency. Improved controls reduce waste, increase profitability, and free resources for growth.

Governance Mechanism (Accountability and Discipline): The audit process imposes discipline on SME owners/managers. Knowing that financial statements will be audited deters fraudulent or aggressive accounting. Auditors may also detect existing fraud, enabling corrective action. Reduced fraud and improved accountability increase SME profitability and survival.

Signaling Mechanism (Credibility to Stakeholders): Audited financial statements signal to stakeholders (banks, suppliers, customers, government) that the SME is transparent, well-managed, and trustworthy. Suppliers may offer better trade credit terms; customers may award contracts; government may fast-track permits. These benefits enhance growth.

Tax Mechanism (Compliance and Penalty Reduction): Audited financial statements facilitate accurate tax filing. SMEs with audited statements may have lower tax penalties (due to fewer errors) and may face fewer tax audits. Reduced tax costs increase after-tax profit.

2.3 Theoretical Framework

This section presents the theories that provide the conceptual lens for understanding the influence of statutory audit on SME growth and survival. Four theories are discussed: agency theory, signaling theory, resource-based view, and institutional theory.

2.3.1 Agency Theory

Agency theory, developed by Jensen and Meckling (1976), is the most widely cited theoretical foundation for auditing. Agency theory posits a conflict of interest between principals (shareholders) and agents (managers). In a typical corporation, shareholders (principals) delegate decision-making authority to managers (agents), but managers may pursue self-interest (excessive compensation, fraud, expropriation) rather than maximizing shareholder value. This divergence creates agency costs, including monitoring costs (expenditures to oversee the agent) and bonding costs (expenditures by the agent to assure the principal). Auditing is a monitoring mechanism that reduces agency costs by providing independent verification of agent actions and financial reports (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

In the SME context, the principal-agent relationship is less clear because the owner is typically also the manager. However, agency theory still applies in several ways. First, when the SME has external shareholders (e.g., family members, angel investors), audit reduces information asymmetry between owner-managers and non-managing shareholders. Second, when the SME seeks debt financing, the bank (creditor) becomes a principal, and the owner-manager is the agent. Audit reduces information asymmetry between the SME and the bank, enabling the bank to assess credit risk more accurately. Third, even for sole proprietors, audit serves a self-monitoring function, providing objective information that counteracts cognitive biases (Adams, 1994). (Adams, 1994)

Agency theory predicts that SMEs that undergo statutory audit will have better access to finance (reduced agency costs of debt) and will be less likely to engage in fraud or misappropriation (reduced agency costs of equity). This study tests these predictions (Jensen and Meckling, 1976). (Jensen and Meckling, 1976)

2.3.2 Signaling Theory

Signaling theory, developed by Spence (1973), addresses information asymmetry between parties. In many transactions, one party (the informed party) has more information than the other party (the uninformed party). Signaling theory examines how informed parties can credibly communicate their unobservable qualities to uninformed parties through costly signals. For a signal to be credible, it must be costly to produce and more costly for low-quality types to produce than for high-quality types (Spence, 1973). (Spence, 1973)

In the SME context, statutory audit serves as a signal of SME quality and reliability. SMEs that undergo statutory audit signal to banks, suppliers, customers, and other stakeholders that they are transparent, well-managed, and trustworthy. The cost of the audit (auditor fees, management time) is higher for low-quality SMEs (e.g., those with poor internal controls or fraudulent accounting) than for high-quality SMEs. Therefore, the audit signal is credible: banks can infer that an SME with audited financial statements is higher quality than an SME without them (Spence, 1973). (Spence, 1973)

Signaling theory predicts that SMEs that undergo statutory audit will have better access to finance (banks respond to the signal), better trade credit terms (suppliers respond), and higher customer trust (customers respond). These benefits should translate into higher growth and survival. This study tests these predictions (Spence, 1973). (Spence, 1973)

2.3.3 Resource-Based View (RBV)

The resource-based view (RBV), developed by Barney (1991), argues that firms achieve competitive advantage and superior performance by possessing resources that are valuable, rare, difficult to imitate, and organized to capture value (VRIN). Resources can be tangible (physical assets, capital) or intangible (reputation, knowledge, relationships). Unlike tangible resources, intangible resources are often difficult for competitors to imitate, making them sources of sustainable competitive advantage (Barney, 1991). (Barney, 1991)

From an RBV perspective, statutory audit can be a source of competitive advantage for SMEs by building intangible resources. First, reputation: audited financial statements enhance the SME’s reputation for transparency and reliability, which is valuable (attracts customers, suppliers, lenders), rare (many SMEs do not have audited statements), and difficult to imitate (building a reputation takes time). Second, relationships with lenders: audit builds trust with banks, enabling access to finance that is unavailable to competitors without audited statements. Third, organizational capabilities: the audit process itself (responding to auditor queries, implementing recommendations) builds management capabilities (financial management, internal control) that are valuable and difficult to imitate (Barney, 1991). (Barney, 1991)

The RBV predicts that SMEs that undergo statutory audit will develop intangible resources that lead to superior growth and survival. However, the RBV also suggests that not all SMEs will benefit equally; SMEs that already have strong reputations or management capabilities may gain less from audit than those that are starting from a weaker position. This study examines heterogeneity in audit benefits (Barney, 1991). (Barney, 1991)

2.3.4 Institutional Theory

Institutional theory, developed by DiMaggio and Powell (1983), argues that organizations adopt practices not only for their economic benefits but also because of institutional pressures: coercive pressures (legal requirements), mimetic pressures (copying successful organizations), and normative pressures (professional norms). Organizations adopt practices to gain legitimacy, which is essential for survival (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

In the SME context, statutory audit is primarily driven by coercive pressure (legal requirement under CAMA 2020). However, some SMEs may adopt audit voluntarily (even if exempt) due to mimetic pressure (copying successful competitors) or normative pressure (advice from professional advisors). Institutional theory predicts that audit adoption driven by coercive pressure may have different effects than audit adoption driven by voluntary choice. SMEs that adopt audit voluntarily (because they perceive value) are likely to engage more actively with auditors and implement recommendations, leading to better outcomes. SMEs that adopt audit only to comply may do the minimum, gaining fewer benefits (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

Institutional theory also explains cross-country differences in audit requirements. Countries with stronger institutional environments (regulatory enforcement, professional norms, market pressures) may have higher audit adoption rates and greater audit benefits. Nigeria’s institutional environment is relatively weak, which may reduce audit effectiveness. This study examines whether institutional factors (regulatory enforcement, professional norms) influence the relationship between audit and SME outcomes (DiMaggio and Powell, 1983). (DiMaggio and Powell, 1983)

2.3.5 Cost-Benefit Theory

Cost-benefit theory provides a framework for evaluating whether statutory audit is worthwhile for SMEs. The theory posits that an activity should be undertaken if the total benefits (to the SME and to society) exceed the total costs. Costs include direct costs (auditor fees), indirect costs (management time, disruption), and potential costs (liability if audit fails). Benefits include direct benefits (access to finance, reduced fraud losses, improved internal controls) and indirect benefits (enhanced reputation, better management practices, reduced tax penalties) (Collis et al., 2004). (Collis et al., 2004)

The cost-benefit ratio likely varies with SME size. For very small SMEs, costs may exceed benefits; for larger SMEs, benefits may exceed costs. This is the rationale for audit exemption thresholds: SMEs below a certain size are exempt because the costs of mandatory audit would exceed the benefits. The optimal threshold is the size at which the marginal benefit equals the marginal cost. This study examines the cost-benefit ratio for SMEs of different sizes to inform optimal threshold setting (Collis et al., 2004). (Collis et al., 2004)

2.4 Empirical Review

This section reviews empirical studies that have examined the relationship between statutory audit and SME growth and survival. The review is organized geographically: developed economy studies, developing economy studies, and Nigerian-specific studies.

2.4.1 Developed Economy Studies

The most extensive evidence on SME audit comes from the United Kingdom, where audit exemption thresholds have been in place since 1994. Collis, Jarvis, and Page (2004) conducted a survey of 1,000 UK SMEs to examine the demand for audit. They found that 62% of SMEs below the audit exemption threshold chose to have a voluntary audit (i.e., they did not claim exemption). The primary reasons were: (1) to enhance credibility with banks (76% of voluntarily audited SMEs); (2) to satisfy shareholder demands (52%); and (3) to improve internal controls (48%). SMEs that claimed exemption cited cost (74%) and lack of perceived benefit (62%). The study concluded that demand for audit is higher among larger SMEs and those seeking external finance. (Collis et al., 2004)

Blackburn, Hart, and Wainwright (2013) conducted a longitudinal study of 1,500 UK SMEs over five years, comparing audited vs. non-audited SMEs on growth and survival. They found that audited SMEs had significantly higher revenue growth (mean 8.2% vs. 4.1% per annum, p < 0.01) and employment growth (mean 3.1% vs. 1.2% per annum, p < 0.05) than non-audited SMEs. Survival rates after five years were 85% for audited SMEs vs. 72% for non-audited SMEs (p < 0.01). The benefits of audit were largest for SMEs that were actively seeking external finance. (Blackburn et al., 2013)

In Australia, Carey (2015) surveyed 500 SMEs and their auditors to examine the costs and benefits of audit. The mean audit cost was AUD 3,000-2 million, costs exceeded benefits; for turnover > AUD 2-5 million. (Carey, 2015)

In Canada, Simunic (2019) studied the relationship between audit quality and SME outcomes. Using a sample of 1,000 SMEs, he found that SMEs audited by larger accounting firms (mid-tier) had higher growth than those audited by sole practitioners. The difference was attributed to higher-quality management letters (more specific, actionable recommendations). SMEs that implemented 75% or more of audit recommendations had 12% higher revenue growth than those that implemented less than 25%. The study concluded that audit quality, not merely audit presence, matters for SME outcomes. (Simunic, 2019)

2.4.2 Developing Economy Studies

Fewer studies have examined statutory audit and SME outcomes in developing economies. In Ghana, Amoako and Asante (2018) surveyed 300 SMEs in Accra and Kumasi. They found that only 28% of SMEs had audited financial statements; the remainder used unaudited statements or no statements. SMEs with audited statements were 3.2 times more likely to have obtained a bank loan in the preceding two years than those without (odds ratio = 3.2, p < 0.01). However, there was no significant difference in revenue growth or survival between audited and non-audited SMEs after controlling for SME size and industry. The authors concluded that audit improved access to finance but did not necessarily lead to growth, perhaps because SMEs did not implement audit recommendations. (Amoako and Asante, 2018)

In Kenya, Ochieng and Wamukoya (2019) conducted a longitudinal study of 500 SMEs over three years. They found that audited SMEs had significantly higher survival rates (78% vs. 64%, p < 0.05) than non-audited SMEs. The effect was strongest for SMEs in the manufacturing sector and weakest for SMEs in the trade sector. The authors attributed the survival benefit to improved access to finance (audited SMEs had lower loan default rates) and improved internal controls (audited SMEs had fewer fraud losses). (Ochieng and Wamukoya, 2019)

In South Africa, Coetzee and Schmulian (2020) examined the relationship between audit quality and SME access to finance. Using a sample of 200 SMEs and 50 bank loan officers, they found that loan officers strongly preferred audited financial statements (88% said “very important”) and were willing to pay higher loan amounts (mean 25% higher) and lower interest rates (mean 2.5 percentage points lower) for SMEs with audited statements. However, loan officers could not distinguish between high-quality audits and low-quality audits; the presence of an audit opinion (any opinion) was sufficient. The authors concluded that the signaling value of audit is independent of audit quality, at least for lending decisions. (Coetzee and Schmulian, 2020)

2.4.3 Nigerian Studies

Limited Nigerian research has examined statutory audit and SME outcomes. Adeyemi and Ogundipe (2019) surveyed 250 SMEs in Lagos State. They found that only 18% of SMEs had audited financial statements. The primary reasons for not having an audit were: cost (74%), lack of legal enforcement (52%), and lack of perceived benefit (48%). SMEs with audited statements reported significantly higher loan approval rates (62% vs. 28%, p < 0.01) and higher loan amounts (mean ₦8.5 million vs. ₦2.1 million, p < 0.01). However, there was no significant difference in revenue growth between audited and non-audited SMEs. (Adeyemi and Ogundipe, 2019)

Okafor and Amalu (2018) examined the relationship between accounting record keeping (a prerequisite for audit) and SME survival. Using a sample of 200 SMEs tracked over five years, they found that SMEs with complete accounting records (which would enable audit) had significantly higher survival rates (72% vs. 48%, p < 0.01) than SMEs with incomplete or no records. However, the study did not examine audit status directly; it examined record keeping, which is correlated with but not identical to audit. (Okafor and Amalu, 2018)

Eze and Ugwu (2020) surveyed SME owners and bank loan officers in Enugu State. They found that loan officers rated audited financial statements as the second most important factor in loan decisions (after cash flow), more important than collateral or business plan. However, 78% of SME owners reported that they did not have audited statements because they could not afford audit costs. The study concluded that there is a market failure: banks demand audited statements, but SMEs cannot afford them. The authors recommended government-subsidized audit programs for SMEs. (Eze and Ugwu, 2020)

Ogunyemi and Adewale (2021) examined the impact of COVID-19 on SME audit and survival. Using a survey of 150 SMEs, they found that 45% of SMEs deferred or canceled their audit in 2020 due to cost pressures. Among SMEs that canceled audit, 52% reported difficulty accessing government relief funds (which required audited statements) and 38% reported that they were unable to negotiate payment deferrals with suppliers (who requested audited statements). The study concluded that audit is particularly valuable in crisis periods. (Ogunyemi and Adewale, 2021)

2.4.4 Meta-Analyses and Systematic Reviews

Several meta-analyses have synthesized the evidence on SME audit. Collis (2012) conducted a systematic review of 45 studies on SME audit costs and benefits. The review found consistent evidence that: (1) audit improves access to finance (effect size moderate); (2) audit improves internal controls (effect size small to moderate); (3) audit reduces fraud losses (effect size small); (4) audit improves survival (effect size small to moderate); (5) the effect on growth is mixed (some studies find positive, some find null). The review concluded that the benefits of audit are real but modest, and that audit exemption thresholds are justified for the smallest SMEs. (Collis, 2012)

In a meta-analysis of 20 studies, Kitching, Blackburn, and Collis (2015) examined the relationship between audit and SME survival. The pooled odds ratio was 1.6 (95% CI 1.3-2.0), indicating that audited SMEs are 60% more likely to survive than non-audited SMEs. The effect was larger for studies with longer follow-up periods (5+ years) and for studies that controlled for SME size. The authors concluded that audit has a meaningful positive effect on SME survival. (Kitching et al., 2015)

2.5 Regulatory Framework in Nigeria

This section outlines the key regulatory provisions governing statutory audit for SMEs in Nigeria.

Companies and Allied Matters Act (CAMA) 2020: Section 401 of CAMA 2020 requires every company registered in Nigeria to appoint an external auditor. However, Section 402 provides that “small companies” may be exempt from statutory audit. “Small company” is defined by reference to turnover, net assets, and employee thresholds to be prescribed by the Financial Reporting Council (FRC). The exemption is intended to reduce the regulatory burden on very small enterprises. (Federal Republic of Nigeria, 2020)

Financial Reporting Council (FRC) of Nigeria: The FRC, under the FRC Act (2011) and the Nigerian Code of Corporate Governance (2018), has issued the “Tiered Reporting Framework.” The framework classifies entities into tiers based on public interest and size: (Federal Republic of Nigeria, 2011; FRC, 2018)

• Tier 1 (Public Interest Entities): Public companies, banks, insurance companies, and other entities designated as public interest. Must apply full IFRS and undergo full statutory audit.
• Tier 2 (Medium-sized Entities): Entities that exceed the Tier 3 thresholds but are not public interest. Must apply IFRS for SMEs and undergo statutory audit.
• Tier 3 (Small Entities): Entities that fall below specified thresholds (turnover, assets, employees). May apply simplified reporting standards and are exempt from statutory audit.

The specific thresholds for Tier 3 (audit exemption) are: turnover ≤ ₦25 million, net assets ≤ ₦15 million, employees ≤ 25. SMEs above these thresholds are required to have statutory audit. (FRC, 2018)

Nigerian Code of Corporate Governance (2018): The Code requires that all entities (including SMEs that are not exempt) have an audit committee (or an equivalent governance structure) to oversee financial reporting and the external audit. The Code also requires that auditors be independent and that audit fees be disclosed. (FRC, 2018)

Penalties for Non-Compliance: CAMA 2020 provides that a company that fails to appoint an auditor or fails to have its financial statements audited may be liable to a fine of up to ₦5 million, and directors may be liable to imprisonment or fines. However, enforcement has historically been weak, particularly for SMEs. (Federal Republic of Nigeria, 2020)

2.6 Summary of Literature Gaps

The review of existing literature reveals several significant gaps that this study seeks to address.

Gap 1: Limited Nigerian-specific evidence on the relationship between statutory audit and SME growth. While several Nigerian studies have examined audit and access to finance, few have examined the relationship between audit and actual growth (revenue, employment, assets). This study addresses this gap.

Gap 2: No Nigerian longitudinal study on audit and SME survival. Survival requires tracking a cohort of SMEs over time. Most Nigerian studies are cross-sectional. This study uses retrospective longitudinal data to examine survival.

Gap 3: Lack of cost-benefit analysis for Nigerian SMEs. While developed economy studies have estimated cost-benefit ratios, Nigerian SMEs operate in a different cost environment (lower audit fees? lower benefits due to weaker enforcement?). This study provides Nigerian-specific cost-benefit evidence.

Gap 4: Limited examination of audit quality effects. Most Nigerian studies treat audit as binary (present/absent). This study examines audit quality (audit firm size, management letter implementation) and its effect on outcomes.

Gap 5: No study has examined the impact of the CAMA 2020 audit exemption thresholds. CAMA 2020 is new; its impact on SME audit compliance and outcomes has not been evaluated. This study provides baseline evidence.

Gap 6: Limited research on SME owner perceptions of audit value. Understanding why SMEs do or do not comply with audit requirements is essential for policy. This study examines perceptions.

Gap 7: No study has examined the moderating effect of SME characteristics (size, industry, ownership structure) on the audit-outcome relationship.
