THE USEFULNESS OF FINANCIAL STATEMENTS IN ASSESSING THE PERFORMANCE OF COMPANIES AS GUIDE TO INVESTMENT DECISIONS

CHAPTER ONE: INTRODUCTION

1.1 Background of Study

Financial statements are formal records of the financial activities and position of a business, person, or other entity, presented in a structured manner that is easy to understand (International Financial Reporting Standards [IFRS] Foundation, 2021). They typically include the statement of financial position (balance sheet), statement of profit or loss and other comprehensive income (income statement), statement of changes in equity, statement of cash flows, and accompanying notes (International Accounting Standards Board [IASB], 2018). These statements provide a historical record of an entity’s financial performance and position, enabling stakeholders—including investors, creditors, regulators, and management—to make informed economic decisions (Penman, 2019). The primary objective of financial reporting, as articulated by the IASB Conceptual Framework, is to provide financial information about the reporting entity that is useful to existing and potential investors, lenders, and other creditors in making decisions about providing resources to the entity (IASB, 2018).

The usefulness of financial statements stems from their fundamental qualitative characteristics: relevance and faithful representation, as well as enhancing qualitative characteristics including comparability, verifiability, timeliness, and understandability (IFRS Foundation, 2021). Relevant financial information is capable of making a difference in user decisions, either by confirming past expectations (confirmatory value) or predicting future outcomes (predictive value) (Barth, 2019). Faithful representation means that the information is complete, neutral, and free from error (Deegan, 2020). When financial statements possess these characteristics, they serve as a reliable basis for assessing company performance and guiding investment decisions (Palepu, Healy, & Wright, 2020). However, the degree to which financial statements achieve these characteristics in practice varies across companies and jurisdictions, affecting their usefulness for investment decision-making (Penman, 2019).

Investment decisions involve the allocation of capital by individuals or institutions to various assets, including equity securities (shares), debt securities (bonds), and other financial instruments, with the expectation of generating future returns (Bodie, Kane, & Marcus, 2021). Investors seek to maximize returns while managing risk, requiring them to evaluate potential investments carefully before committing funds (Damodaran, 2020). Financial statements are a primary source of information for this evaluation, providing data on a company’s profitability, liquidity, solvency, efficiency, and growth prospects (Subramanyam, 2019). Investors use financial statement analysis—including ratio analysis, trend analysis, common-size analysis, and cash flow analysis—to assess a company’s past performance, current financial health, and future potential (Robinson, Henry, Pirie, & Broihahn, 2020). Without reliable financial statements, investment decisions would be based on speculation, rumor, or incomplete information, leading to inefficient capital allocation (Fama, 2020).

The statement of profit or loss (income statement) provides information about a company’s financial performance over a period, showing revenues, expenses, and resulting profit or loss (IASB, 2018). Investors use this statement to assess profitability, earnings growth, profit margins, and the sustainability of earnings (Penman, 2019). Key metrics derived from the income statement include gross profit margin (gross profit divided by revenue), operating profit margin (operating profit divided by revenue), net profit margin (net profit divided by revenue), earnings per share (EPS), and return on equity (ROE) (Palepu et al., 2020). Trends in these metrics over time, and comparisons with industry peers, help investors identify companies with superior profitability and competitive advantages (Subramanyam, 2019). However, the income statement is subject to estimation and judgment (e.g., depreciation methods, inventory valuation, revenue recognition), which can affect its usefulness (Barth, 2019).

The statement of financial position (balance sheet) provides a snapshot of a company’s assets, liabilities, and equity at a specific point in time (IASB, 2018). Assets represent resources controlled by the entity from which future economic benefits are expected; liabilities represent present obligations that will result in outflows of resources; equity represents the residual interest of owners (Deegan, 2020). Investors use the balance sheet to assess liquidity (ability to meet short-term obligations), solvency (ability to meet long-term obligations), and financial flexibility (ability to adapt to changing circumstances) (Robinson et al., 2020). Key metrics derived from the balance sheet include the current ratio (current assets divided by current liabilities), quick ratio (liquid assets divided by current liabilities), debt-to-equity ratio (total liabilities divided by total equity), and working capital (current assets minus current liabilities) (Penman, 2019). The balance sheet also reveals the company’s capital structure, asset composition, and off-balance-sheet financing arrangements (Palepu et al., 2020).

The statement of cash flows provides information about the cash inflows and outflows from operating, investing, and financing activities over a period (IASB, 2018). Cash flow from operating activities is particularly important to investors because it reflects the cash generated by the company’s core business operations, as opposed to accounting profits that may include non-cash items (e.g., depreciation, amortization, provisions) (Damodaran, 2020). A company can report accounting profits while experiencing negative operating cash flow (e.g., due to increasing receivables or inventory), which may signal future problems (Subramanyam, 2019). Investors use cash flow metrics such as operating cash flow per share, free cash flow (operating cash flow minus capital expenditures), and cash flow return on investment (Bodie et al., 2021). The cash flow statement is generally considered less susceptible to managerial manipulation than the income statement, enhancing its usefulness for investment decisions (Penman, 2019).

The accompanying notes to the financial statements provide additional detail and context that are essential for proper interpretation (IFRS Foundation, 2021). Notes disclose accounting policies, significant judgments and estimates, contingent liabilities, commitments, related party transactions, segment information, fair value measurements, and other items not readily apparent from the face of the statements (IASB, 2018). For example, a company with a large amount of debt may have covenants that restrict its operations; this information appears in the notes, not on the face of the balance sheet (Deegan, 2020). Investors who ignore the notes may miss critical information that affects investment decisions (Barth, 2019). The complexity and length of notes (often exceeding 100 pages for large companies) can, however, reduce their usefulness for individual investors with limited time and expertise (Palepu et al., 2020).

Financial statement analysis involves the application of various techniques to extract meaning from financial statements and support investment decisions (Robinson et al., 2020). Ratio analysis involves calculating and interpreting relationships between financial statement items, such as profitability ratios (gross margin, net margin, ROE, ROA), liquidity ratios (current ratio, quick ratio), solvency ratios (debt-to-equity, interest coverage), efficiency ratios (inventory turnover, receivables turnover, asset turnover), and market ratios (price-to-earnings, price-to-book, dividend yield) (Penman, 2019). Trend analysis (horizontal analysis) examines changes in financial statement items over multiple periods to identify growth patterns, deterioration, or cyclicality (Subramanyam, 2019). Common-size analysis (vertical analysis) expresses each item as a percentage of a base (e.g., revenue for the income statement, total assets for the balance sheet) to facilitate comparison across companies of different sizes (Palepu et al., 2020).

Comparative analysis involves benchmarking a company’s financial ratios against its industry peers, sector averages, or competitors, providing context for assessing relative performance (Robinson et al., 2020). A company with a 10% net profit margin might appear profitable, but if industry peers average 15%, the company may be underperforming (Damodaran, 2020). Cash flow analysis focuses on the sources and uses of cash, evaluating whether operating cash flow is sufficient to fund investing and financing activities (Bodie et al., 2021). DuPont analysis decomposes return on equity (ROE) into three components: profit margin (profitability), asset turnover (efficiency), and financial leverage (equity multiplier), helping investors identify the drivers of shareholder returns (Penman, 2019). Each technique provides a different lens on company performance, and effective investors use multiple techniques in combination (Subramanyam, 2019).

Investment decisions based on financial statement analysis can take various forms (Bodie et al., 2021). Equity investment decisions involve buying, holding, or selling shares of companies. Investors may adopt a value investing approach (seeking undervalued companies with strong fundamentals), growth investing approach (seeking companies with high earnings growth potential), or income investing approach (seeking companies with stable dividends) (Damodaran, 2020). Debt investment decisions involve investing in corporate bonds or commercial paper, requiring analysis of the company’s ability to service its debt (interest coverage, cash flow adequacy, collateral) (Penman, 2019). Portfolio allocation decisions involve weighting different investments within a portfolio; financial statement analysis informs which companies or sectors to overweight or underweight (Robinson et al., 2020). In all cases, the quality and reliability of financial statements directly affect the quality of investment decisions (Fama, 2020).

The Nigerian capital market provides a relevant context for studying the usefulness of financial statements for investment decisions (Securities and Exchange Commission [SEC], Nigeria, 2022). The Nigerian Stock Exchange (NGX) lists over 150 companies across various sectors, including banking, consumer goods, industrial, oil and gas, and telecommunications (NGX, 2023). Investors—ranging from institutional investors (pension funds, mutual funds, insurance companies) to individual retail investors—rely on the financial statements of listed companies to make investment decisions (Adelegan, 2019). The adoption of IFRS in Nigeria since 2012 has improved the comparability and quality of financial statements, but challenges remain, including weak enforcement, late filing, and concerns about earnings management (Okon & Akpan, 2020). Understanding how useful Nigerian investors actually find these financial statements, and what factors affect their usefulness, is an important empirical question (Okafor & Mbagwu, 2021).

The usefulness of financial statements for investment decisions is not automatic; several factors can impair usefulness (Barth, 2019). Earnings management occurs when managers use judgment in financial reporting to alter reported earnings to mislead stakeholders or influence contractual outcomes (Healy & Wahlen, 2019). Companies with aggressive earnings management produce financial statements that are less useful for investment decisions because reported earnings do not reflect economic reality (Dechow, Ge, & Schrand, 2020). Creative accounting involves exploiting loopholes in accounting standards to present a more favourable picture than justified (Penman, 2019). Fraudulent financial reporting involves intentional misrepresentation of financial statements, as seen in high-profile cases like Enron, WorldCom, and, in Nigeria, the Cadbury Nigeria case (Okoye & Maimako, 2019). Fraudulent statements can mislead investors into making poor investment decisions, with potentially catastrophic losses (Damodaran, 2020).

Complexity of financial statements can also reduce usefulness, particularly for individual retail investors who may lack accounting training (Palepu et al., 2020). IFRS financial statements can be hundreds of pages long, with dense technical language, making them challenging for non-experts to interpret (Deegan, 2020). Timeliness is another factor: financial statements are issued weeks or months after the reporting period end; by the time investors receive them, the information may be stale, and the company’s circumstances may have changed (Penman, 2019). In Nigeria, some listed companies file their financial statements late, sometimes months after the regulatory deadline, further reducing timeliness (SEC Nigeria, 2022). Comparability across companies can be impaired by different accounting policy choices (e.g., different depreciation methods, inventory valuation methods, revenue recognition policies), even under IFRS (IFRS Foundation, 2021).

The efficient market hypothesis (EMH) provides a theoretical perspective on the usefulness of financial statements (Fama, 2020). In its strong form, EMH posits that all information, public and private, is immediately reflected in stock prices, making it impossible to earn abnormal returns through financial statement analysis. In its semi-strong form, EMH posits that all publicly available information (including financial statements) is reflected in prices, so fundamental analysis cannot consistently beat the market. In its weak form, EMH posits that only past price information is reflected, leaving room for fundamental analysis to generate abnormal returns (Bodie et al., 2021). The empirical evidence on EMH is mixed; many investors and professional money managers believe that careful financial statement analysis can identify undervalued or overvalued securities, particularly in less efficient markets like Nigeria (Adelegan, 2019).

From a theoretical perspective, this study is supported by three theories: Decision-Usefulness Theory, which holds that the primary objective of financial reporting is to provide information useful for investment, credit, and similar decisions (IASB, 2018; Beaver, 2019); Efficient Market Hypothesis (EMH) , which posits that security prices reflect available information, including financial statements (Fama, 2020); and Fundamental Analysis Theory, which asserts that a company’s intrinsic value can be estimated through rigorous analysis of its financial statements and economic environment (Graham & Dodd, 2019). These theories provide competing and complementary predictions about the usefulness of financial statements for investment decisions, and this study aims to evaluate them in the Nigerian context.

In summary, financial statements are a primary source of information for investment decisions, providing data on profitability, liquidity, solvency, efficiency, and cash flows. Investors use various analytical techniques—ratio analysis, trend analysis, common-size analysis, comparative analysis, cash flow analysis, DuPont analysis—to assess company performance and guide investment decisions. However, the usefulness of financial statements can be impaired by earnings management, creative accounting, fraud, complexity, timeliness issues, and lack of comparability. The Nigerian capital market, with its growing number of listed companies and investors, provides an important context for studying these issues. This study aims to empirically investigate the usefulness of financial statements in assessing the performance of companies as a guide to investment decisions, generating insights for investors, companies, regulators, and standard-setters.

1.2 Statement of Problems

Despite the theoretical importance of financial statements as a guide to investment decisions, empirical evidence suggests that many investors in the Nigerian capital market do not rely primarily on financial statements when making investment decisions, or do not find them sufficiently useful. Observed problems include: low retail investor participation in the Nigerian stock market relative to other emerging markets, high market volatility driven by speculation rather than fundamentals, frequent cases of share price movements that are inconsistent with underlying financial performance, and instances where companies with poor financial statements continue to attract investment while fundamentally strong companies are overlooked. Furthermore, concerns about the quality of financial statements—including late filing, restatements, earnings management, and in some cases fraud—raise questions about their reliability for investment decisions. There is also a gap between the sophisticated financial statement analysis techniques taught in theory and the simpler (or non-existent) analysis practices of many individual investors. The problem this study addresses is the need to empirically assess the actual usefulness of financial statements to investors in assessing company performance and guiding investment decisions, identifying the factors that enhance or impair this usefulness, and recommending improvements for investors, companies, and regulators.

1.3 Aim of the Study

The specific aim of this research work is to examine the usefulness of financial statements in assessing the performance of companies as a guide to investment decisions, with a view to determining the extent to which investors rely on financial statements, the analytical techniques they employ, the challenges they face, and how usefulness can be enhanced.

1.4 Objectives of the Study

1. To determine the extent to which investors use financial statements (including income statement, balance sheet, cash flow statement, and notes) as a source of information for investment decisions.
2. To assess the relationship between key financial statement ratios (profitability, liquidity, solvency, efficiency, and market ratios) and investment decision outcomes (buy, hold, sell).
3. To examine the effect of financial statement quality characteristics (relevance, faithful representation, comparability, verifiability, timeliness, understandability) on investor confidence in using financial statements for investment decisions.
4. To evaluate the challenges (including earnings management, complexity, late filing, and lack of comparability) that limit the usefulness of financial statements for investment decisions in the Nigerian context.
5. To investigate the differences in financial statement usefulness perception and usage between different categories of investors (institutional investors, professional individual investors, and non-professional individual investors).

1.5 Research Questions

1. To what extent do investors use financial statements (including income statement, balance sheet, cash flow statement, and notes) as a source of information for investment decisions?
2. What is the relationship between key financial statement ratios (profitability, liquidity, solvency, efficiency, and market ratios) and investment decision outcomes (buy, hold, sell)?

5. What are the differences in financial statement usefulness perception and usage between different categories of investors (institutional investors, professional individual investors, and non-professional individual investors)?

1.6 Research Hypotheses

Hypothesis One

• H₀ (Null): Investors do not significantly use financial statements (including income statement, balance sheet, cash flow statement, and notes) as a source of information for investment decisions.
• H₁ (Alternative): Investors significantly use financial statements (including income statement, balance sheet, cash flow statement, and notes) as a source of information for investment decisions.

Hypothesis Two

• H₀ (Null): There is no significant relationship between key financial statement ratios (profitability, liquidity, solvency, efficiency, and market ratios) and investment decision outcomes (buy, hold, sell).
• H₁ (Alternative): There is a significant relationship between key financial statement ratios (profitability, liquidity, solvency, efficiency, and market ratios) and investment decision outcomes (buy, hold, sell).

Hypothesis Three

• H₀ (Null): Financial statement quality characteristics (relevance, faithful representation, comparability, verifiability, timeliness, understandability) have no significant effect on investor confidence in using financial statements for investment decisions.
• H₁ (Alternative): Financial statement quality characteristics (relevance, faithful representation, comparability, verifiability, timeliness, understandability) have a significant effect on investor confidence in using financial statements for investment decisions.

Hypothesis Five

• H₀ (Null): There are no significant differences in financial statement usefulness perception and usage between different categories of investors (institutional investors, professional individual investors, and non-professional individual investors).
• H₁ (Alternative): There are significant differences in financial statement usefulness perception and usage between different categories of investors (institutional investors, professional individual investors, and non-professional individual investors).

1.7 Justification of the Study

This study is justified on several grounds. First, despite the central role of financial statements in investment decision-making theory, there is limited empirical evidence on how investors in the Nigerian capital market actually use (or do not use) financial statements, creating a gap between theory and practice. Second, the Nigerian capital market is undergoing significant development, including the demutualization of the Nigerian Stock Exchange, increased foreign portfolio investment, and regulatory reforms by the Securities and Exchange Commission; understanding how investors use financial statements is essential for market development. Third, persistent concerns about financial reporting quality in Nigeria (including earnings management, late filing, and fraud) raise questions about whether financial statements are sufficiently reliable to guide investment decisions; this study will provide empirical evidence on this question. Fourth, the study includes different categories of investors (institutional, professional individual, non-professional individual), enabling comparative analysis of information needs and usage patterns across investor types. Fifth, the findings will inform investors (on effective use of financial statements), companies (on improving financial reporting usefulness), regulators (on enforcement priorities and investor education), and standard-setters (on Nigerian-specific implementation issues).

1.8 Significance of the Study

The findings of this research will be significant to several stakeholders. To investors (both existing and potential), the study will provide evidence on which financial statement items and ratios are most useful for investment decisions, enabling more effective analysis and better-informed investment choices. To companies and their financial reporting preparers, the findings will highlight which aspects of financial statements investors find most valuable (and which are ignored), enabling more efficient and decision-useful financial reporting. To regulators, including the Securities and Exchange Commission (SEC) Nigeria and the Nigerian Exchange Group (NGX), the study will identify gaps in financial reporting quality and investor education that require regulatory attention, enforcement actions, or market development initiatives. To accounting standard-setters (the Financial Reporting Council of Nigeria and the IASB), the findings will provide evidence on whether IFRS financial statements are meeting their decision-usefulness objective in an emerging market context, potentially informing future standard-setting or implementation guidance. To academic researchers in accounting, finance, and investment, the study will contribute empirical evidence from an under-researched market (Nigeria), testing and potentially extending decision-usefulness theory, efficient market hypothesis, and fundamental analysis theory.

1.9 Scope of the Study

The scope of this study is delimited to the usefulness of financial statements in assessing the performance of companies as a guide to investment decisions. The study focuses on equity investments (shares) in companies listed on the Nigerian Exchange (NGX), excluding debt investments, real estate investments, and other asset classes. The financial statements examined are the annual financial statements (including statement of financial position, statement of profit or loss, statement of cash flows, statement of changes in equity, and notes) prepared under IFRS as adopted in Nigeria. The study covers the period from 2018 to 2022 (five years), capturing recent financial reporting practices and investment patterns. The study examines three categories of investors: institutional investors (pension funds, mutual funds, insurance companies, asset managers), professional individual investors (individuals with formal training in accounting, finance, or investment), and non-professional individual investors (retail investors without formal training). The study does not extend to investment decisions in unlisted companies, foreign companies not listed on NGX, or alternative investments (bonds, treasury bills, real estate, commodities). The study relies on primary data (questionnaires and interviews) from investors and secondary data (financial statements, stock prices, trading volumes) from publicly available sources.

CHAPTER TWO: LITERATURE REVIEW

2.1 Theoretical Review

This study is anchored on three supporting theories that provide a comprehensive theoretical foundation for understanding the usefulness of financial statements in assessing company performance as a guide to investment decisions. These theories are Decision-Usefulness Theory, the Efficient Market Hypothesis (EMH), and Fundamental Analysis Theory. Each theory offers distinct but complementary (and sometimes competing) insights into whether, how, and to what extent financial statements inform investment decisions.

2.1.1 Decision-Usefulness Theory

Decision-Usefulness Theory is the dominant normative theory of financial reporting, serving as the conceptual foundation for the International Accounting Standards Board (IASB) Conceptual Framework and, consequently, for International Financial Reporting Standards (IFRS) (IASB, 2018). The theory holds that the primary objective of financial reporting is to provide financial information about the reporting entity that is useful to existing and potential investors, lenders, and other creditors in making decisions about providing resources to the entity (Beaver, 2019). These decisions include buying, selling, or holding equity and debt instruments; providing or settling loans; and exercising rights to vote on management actions (IASB, 2018). Decision-usefulness is thus an investor-centric theory: financial statements are prepared not for their own sake, but to serve the information needs of capital providers (Barth, 2019).

The theory articulates two fundamental qualitative characteristics that make financial information decision-useful: relevance and faithful representation (IASB, 2018). Relevant financial information is capable of making a difference in user decisions, either by confirming past expectations (confirmatory value) or predicting future outcomes (predictive value) (Deegan, 2020). For investment decisions, predictive value is particularly important: investors use past financial performance (e.g., historical earnings growth) to predict future performance (e.g., future earnings, dividends, share price appreciation) (Penman, 2019). Faithful representation means that the information is complete, neutral, and free from error (IFRS Foundation, 2021). Financial statements that are biased (e.g., systematically overstating assets or understating liabilities) or incomplete (e.g., omitting contingent liabilities) cannot be decision-useful, even if relevant (Barth, 2019).

Decision-Usefulness Theory also identifies four enhancing qualitative characteristics: comparability, verifiability, timeliness, and understandability (IASB, 2018). Comparability enables investors to identify similarities and differences between companies, essential for portfolio allocation decisions (Palepu, Healy, & Wright, 2020). Verifiability (different knowledgeable observers reaching consensus that information is faithfully represented) gives investors confidence in the reliability of financial statements (Deegan, 2020). Timeliness means that information is available to decision-makers before it loses its capacity to influence decisions; stale information is not decision-useful, regardless of its relevance and faithful representation (Subramanyam, 2019). Understandability means that information is presented clearly and concisely, recognizing that users are expected to have reasonable knowledge of business and economic activities (Robinson, Henry, Pirie, & Broihahn, 2020).

Decision-Usefulness Theory has important implications for investment practice (Penman, 2019). First, it implies that investors should be the primary audience for financial reporting; management’s needs (e.g., for internal reporting) and other stakeholders’ needs (e.g., creditors, regulators, employees) are secondary. Second, it implies that financial statements should focus on information that affects investment decisions (e.g., earnings, cash flows, assets, liabilities) rather than information that is merely interesting or regulatory-driven. Third, it implies that standard-setters should prioritize predictive value: financial statements should help investors forecast future cash flows, earnings, and dividends (Barth, 2019). Fourth, it implies that financial statements should be comparable across companies; investors cannot easily compare companies that use different accounting policies (Robinson et al., 2020).

A limitation of Decision-Usefulness Theory is that it assumes that financial statement preparers (management) are willing and able to provide decision-useful information, and that auditors ensure its reliability (Deegan, 2020). In reality, management may have incentives to bias financial statements (e.g., to meet earnings targets, to avoid debt covenant violations, to increase bonuses), reducing decision-usefulness (Healy & Wahlen, 2019). Additionally, the theory does not specify how much information is optimal; financial statements have become increasingly lengthy and complex, potentially reducing rather than enhancing decision-usefulness for many investors (Penman, 2019). Despite these limitations, Decision-Usefulness Theory remains the most widely accepted framework for understanding the purpose of financial reporting and provides the primary theoretical lens for this study.

2.1.2 Efficient Market Hypothesis (EMH)

The Efficient Market Hypothesis (EMH), developed by Eugene Fama (1970) and subsequently refined (Fama, 2020), provides a contrasting (and, in some respects, competing) perspective on the usefulness of financial statements for investment decisions. EMH posits that financial markets are “informationally efficient”: security prices fully reflect all available information at any given time (Fama, 2020). In an efficient market, it is impossible to consistently achieve returns in excess of average market returns on a risk-adjusted basis by using any information that is already available to all market participants, including financial statements (Bodie, Kane, & Marcus, 2021). Thus, if markets are efficient, the usefulness of financial statements for generating abnormal investment returns is zero: financial statement analysis cannot beat the market because share prices already incorporate all publicly available financial information (Malkiel, 2019).

EMH identifies three forms of market efficiency, each with different implications for the usefulness of financial statements (Fama, 2020). Weak-form efficiency holds that current share prices fully reflect all past price and volume information. In a weak-form efficient market, technical analysis (studying past price patterns) cannot generate abnormal returns, but fundamental analysis (studying financial statements) might still be useful because financial statement information is not fully reflected in prices (Bodie et al., 2021). Semi-strong form efficiency holds that current share prices fully reflect all publicly available information, including financial statements, earnings announcements, and other published data. In a semi-strong efficient market, neither technical analysis nor fundamental analysis can generate abnormal returns; investors cannot beat the market by reading financial statements (Malkiel, 2019). Strong-form efficiency holds that current share prices fully reflect all information, public and private (including insider information). In a strong-form efficient market, no one (not even corporate insiders) can consistently generate abnormal returns (Fama, 2020).

The empirical evidence on EMH is mixed (Bodie et al., 2021). Studies of developed markets (particularly the US) provide considerable support for semi-strong efficiency: announcements of earnings, dividends, and other financial information are rapidly incorporated into prices, making it difficult to trade profitably on public financial statements (Malkiel, 2019). However, anomalies exist (e.g., the post-earnings announcement drift, where stock prices continue to drift in the direction of earnings surprises for weeks after the announcement), suggesting that markets are not perfectly efficient (Penman, 2019). In emerging markets like Nigeria, evidence of efficiency is weaker; markets may be less efficient due to lower liquidity, higher transaction costs, fewer analysts, slower information dissemination, and less sophisticated investors (Adelegan, 2019). If Nigerian markets are not semi-strong efficient, financial statement analysis may indeed be useful for generating abnormal returns (Okon & Akpan, 2020).

EMH has important implications for the usefulness of financial statements (Penman, 2019). If markets are efficient (semi-strong or strong), financial statements are still useful—not for generating abnormal returns, but for confirming prices and for other purposes (e.g., assessing management performance, voting on compensation plans). Investors in efficient markets need not analyze financial statements to make investment decisions; they can simply buy and hold a diversified portfolio (index fund) (Bodie et al., 2021). However, even in efficient markets, financial statements provide information that investors use to form their expectations; the efficiency of price adjustment to financial statement information depends on the information being available and credible (Fama, 2020). If financial statements are not decision-useful (e.g., due to earnings management or late filing), market efficiency cannot be achieved because prices will not reflect information that is not available or is unreliable (Beaver, 2019).

A limitation of EMH is the joint hypothesis problem: any test of market efficiency is simultaneously a test of a particular asset pricing model (e.g., the Capital Asset Pricing Model) (Fama, 2020). If abnormal returns appear to exist, it may be because the asset pricing model is wrong (e.g., fails to capture risk correctly), not because markets are inefficient. Additionally, EMH does not preclude the existence of skilled investors who can beat the market; if such investors exist (e.g., Warren Buffett), that challenges the strict form of EMH (Malkiel, 2019). EMH is a useful benchmark but should not be taken as an absolute truth, particularly in emerging markets like Nigeria. This study treats EMH as a theoretical lens for understanding competing claims about financial statement usefulness.

2.1.3 Fundamental Analysis Theory

Fundamental Analysis Theory, associated with the work of Benjamin Graham and David Dodd (1934) and later developed by authors such as Penman (2019) and Damodaran (2020), provides a third perspective on the usefulness of financial statements. Fundamental analysis is the process of determining the intrinsic value of a security (the value justified by its underlying economic fundamentals) by analyzing the company’s financial statements, its management, its industry, and the broader economy (Graham & Dodd, 2019). The central premise of fundamental analysis is that market prices frequently deviate from intrinsic values due to investor irrationality, information asymmetry, or short-term trading pressures, and that disciplined analysis of financial statements can identify these deviations, enabling investors to buy undervalued securities and sell overvalued ones (Penman, 2019).

Fundamental analysis theory distinguishes between intrinsic value (what a company is truly worth, based on its future cash-generating ability) and market price (what investors are currently willing to pay) (Damodaran, 2020). When intrinsic value exceeds market price, the security is undervalued (a buy opportunity); when market price exceeds intrinsic value, the security is overvalued (a sell or avoid opportunity) (Graham & Dodd, 2019). Financial statements are the primary input for estimating intrinsic value, providing data on past performance that, when combined with assumptions about the future, enable discounted cash flow (DCF) or residual income valuation (Penman, 2019). Key financial statement inputs for valuation include: revenues, earnings, operating cash flows, book value of equity, and various ratios derived from these items (Robinson et al., 2020).

Fundamental analysis involves several stages (Damodaran, 2020). Accounting analysis assesses the quality of financial statements, identifying areas where accounting policies, estimates, or management discretion may distort reported numbers (Palepu et al., 2020). Adjustments may be made (e.g., capitalizing operating leases, adjusting for one-time items) to arrive at normalized, comparable numbers (Penman, 2019). Financial ratio analysis calculates and interprets profitability, liquidity, solvency, efficiency, and market ratios, providing insights into the company’s operating performance, financial health, and valuation (Robinson et al., 2020). Cash flow analysis examines the sources and uses of cash, with particular attention to operating cash flow relative to earnings (free cash flow to equity, free cash flow to firm) (Damodaran, 2020). Prospective analysis uses historical financial statement data to forecast future revenues, earnings, cash flows, and ultimately to estimate intrinsic value via discounted cash flow (DCF) or other valuation models (Penman, 2019).

Fundamental analysis theory is most associated with “value investing,” an investment approach popularized by Benjamin Graham and later by Warren Buffett (Graham & Dodd, 2019). Value investors seek to buy securities at a discount to their intrinsic value, providing a “margin of safety” that protects against downside risk (Penman, 2019). Financial statement analysis is central to value investing: value investors scrutinize balance sheets (looking for hidden assets, low debt), income statements (looking for sustainable earnings, profit margins), and cash flow statements (looking for strong operating cash flows) (Damodaran, 2020). In contrast, “growth investors” may focus more on earnings growth trends and price momentum, but still rely on financial statements for basic information (Bodie et al., 2021).

A limitation of fundamental analysis theory is that it requires significant time, expertise, and data (Damodaran, 2020). Individual investors (non-professionals) may not have the skills or resources to conduct rigorous fundamental analysis (Palepu et al., 2020). Additionally, fundamental analysis assumes that financial statements are sufficiently reliable and comparable to support valuation; if financial statements are manipulated or not comparable, fundamental analysis may lead to incorrect intrinsic value estimates (Barth, 2019). Furthermore, even if an investor correctly estimates intrinsic value, the market may take a long time to recognize that value (Keynes’ observation that “markets can remain irrational longer than you can remain solvent”) (Malkiel, 2019). Despite these limitations, fundamental analysis theory remains widely used by professional investors and provides a strong theoretical justification for studying the usefulness of financial statements for investment decisions.

Integration of the Three Theories

The three theories provide complementary and competing perspectives that together form a robust theoretical framework for this study. Decision-Usefulness Theory provides the normative foundation: financial statements should be prepared to help investors make investment decisions, and should possess relevance, faithful representation, comparability, verifiability, timeliness, and understandability. Efficient Market Hypothesis (EMH) provides a positive (descriptive) claim: in efficient markets, financial statement analysis cannot generate abnormal returns because information is already reflected in prices. Fundamental Analysis Theory provides a practical methodology: investors can use financial statements to estimate intrinsic value and identify mispriced securities. This study does not aim to definitively resolve the debate between EMH and fundamental analysis (which is impossible in a single study), but rather to examine the actual practices, perceptions, and challenges of investors in the Nigerian market, contributing empirical evidence that speaks to the conditions under which financial statements are (or are not) decision-useful.

2.2 Conceptual Framework

The conceptual framework for this study is a schematic representation of the relationships between the independent variables (financial statement characteristics and investor characteristics), the mediating variable (financial statement analysis techniques), and the dependent variable (investment decisions). The framework, grounded in the three supporting theories (Decision-Usefulness, EMH, and Fundamental Analysis), posits that the usefulness of financial statements for investment decisions depends on the interaction between the quality of the financial statements themselves, the analytical techniques applied by investors, and the characteristics of the investors. Below is a detailed discussion of the independent, mediating, and dependent variables.

Independent Variables (Financial Statement Characteristics and Investor Characteristics)

The independent variables in this study are the features of financial statements that affect their usefulness, and the characteristics of investors that affect their ability to use financial statements.

A. Financial Statement Characteristics (Quality Dimensions)

1. Relevance: The capacity of financial statement information to make a difference in investment decisions, through predictive value (helping forecast future earnings, cash flows, or dividends) and confirmatory value (confirming or changing past expectations) (IASB, 2018). This variable is measured by investor perceptions of whether financial statement items (e.g., earnings, revenues, operating cash flow) predict future performance and confirm past assessments.
2. Faithful Representation: The degree to which financial statements are complete (include all necessary information), neutral (free from bias), and free from error (accurate) (IFRS Foundation, 2021). This variable is measured by investor confidence in the reliability of reported numbers, perceptions of earnings management, and trust in the audit process.
3. Comparability: The extent to which financial statement information can be compared across different companies and across different periods for the same company (IASB, 2018). This variable is measured by investor perceptions of ease of comparing competitors’ financial statements, consistency of accounting policies over time, and the impact of IFRS adoption on comparability.
4. Verifiability: The degree to which different knowledgeable observers could reach consensus that financial statement information is faithfully represented (Deegan, 2020). This variable is measured by investor confidence that audited numbers are reliable and that the audit process is effective.
5. Timeliness: The availability of financial statement information to investors before it loses its capacity to influence investment decisions (IASB, 2018). This variable is measured by the time lag between the reporting period end and the date financial statements are made available to investors, and investor perceptions of whether information is received in time to be useful.
6. Understandability: The clarity and conciseness of financial statement presentation, including the use of plain language, logical organization, and adequate explanation (IFRS Foundation, 2021). This variable is measured by investor perceptions of whether financial statements are easy to understand, and whether the notes provide helpful clarification.

B. Investor Characteristics

1. Investor Type: Whether the investor is an institutional investor (pension fund, mutual fund, insurance company, asset manager), a professional individual investor (with formal training in accounting/finance), or a non-professional individual investor (no formal training) (Bodie et al., 2021). This variable is measured by classification based on investor self-identification.
2. Investment Horizon: Whether the investor has a short-term (days to months), medium-term (months to a few years), or long-term (years to decades) investment horizon (Damodaran, 2020). This variable is measured by self-reported typical holding period.
3. Investment Approach: Whether the investor identifies as a value investor (seeking undervalued securities based on fundamentals), growth investor (seeking companies with high earnings growth), technical analyst (using price patterns), or passive/index investor (buying and holding diversified portfolios) (Penman, 2019). This variable is measured by self-reported primary investment strategy.

Mediating Variable (Financial Statement Analysis Techniques)

The mediating variable is the extent and nature of financial statement analysis performed by investors. Even if financial statements are of high quality, they are not useful if investors do not analyze them. This variable encompasses:

1. Extent of Usage: How frequently investors refer to each financial statement (income statement, balance sheet, cash flow statement, notes) and to each section within statements (e.g., revenue, profit, assets, liabilities, cash flow from operations) (Robinson et al., 2020). Measured by self-reported usage frequency.
2. Analytical Techniques Applied: Which techniques investors use, including ratio analysis (profitability, liquidity, solvency, efficiency, market ratios), trend analysis (horizontal analysis), common-size analysis (vertical analysis), comparative analysis (benchmarking against peers), cash flow analysis, DuPont analysis, and discounted cash flow valuation (Subramanyam, 2019). Measured by self-reported technique usage.
3. Depth of Analysis: Whether investors simply look at headline numbers (e.g., net profit, earnings per share) or perform deeper analysis (e.g., adjusting for non-recurring items, analyzing segment performance, reading notes) (Penman, 2019). Measured by self-reported depth.

Dependent Variable (Investment Decisions)

The dependent variable in this study is the investment decision outcome influenced by financial statement analysis. This is measured along multiple dimensions:

1. Investment Decision (Buy/Hold/Sell): Whether the investor decides to buy, hold (continue owning), or sell (dispose of) a company’s shares based (in part) on financial statement analysis (Bodie et al., 2021). Measured by self-reported decisions in specific cases or in general.
2. Investment Confidence: The degree of confidence investors have in their investment decisions when they are based on financial statement analysis, compared to decisions based on other information (e.g., tips, news, price momentum) (Palepu et al., 2020). Measured by Likert-scale confidence ratings.
3. Perceived Usefulness: The investor’s overall assessment of how useful financial statements are for making investment decisions, considering the trade-offs (time required, complexity, reliability) (Beaver, 2019). Measured by Likert-scale usefulness ratings.
4. (For non-professional investors who do not use financial statements): Reasons for non-use, including lack of training, lack of time, perceived complexity, perceived irrelevance, or reliance on advice from others (Deegan, 2020). Measured by selection from a list of reasons.

Moderating Variables

The conceptual framework also includes moderating variables (consistent with Contingency Theory, though not a primary theory in this study) that affect the strength of relationships:

• Market conditions (bull market vs. bear market): Investors may rely more on financial statements during volatile or declining markets when speculation is less rewarded.
• Company size (large-cap vs. small-cap): Financial statements may be more useful for large companies with more analyst coverage and less information asymmetry.
• Industry sector (e.g., banking vs. manufacturing vs. consumer goods): Certain industries may have more transparent or comparable financial statements.

Diagrammatic Representation (Described in Text):

The conceptual framework can be visualized as follows:

Independent Variables (Inputs) → Mediating Variable (Process) → Dependent Variable (Outcome)

Independent Variables (Inputs):

• Financial Statement Characteristics (Relevance, Faithful Representation, Comparability, Verifiability, Timeliness, Understandability)
• Investor Characteristics (Type, Horizon, Approach)

Mediating Variable (Process):

• Financial Statement Analysis (Extent of usage, Analytical techniques, Depth of analysis)

Dependent Variable (Outcome):

• Investment Decisions (Buy/Hold/Sell)
• Investment Confidence
• Perceived Usefulness of Financial Statements
• (For non-users) Reasons for non-use

The framework posits that financial statement quality affects investment decisions indirectly through the investor’s analysis process. High-quality financial statements (relevance, faithful representation, etc.) facilitate more effective analysis, which in turn leads to more confident and better-informed investment decisions. However, the relationship is moderated by investor characteristics: even very high-quality financial statements will not be useful to an investor who lacks the training to analyze them (non-professional individual investors) or who relies on other information sources (e.g., tips, price momentum). Conversely, professional individual and institutional investors may be able to extract usefulness even from lower-quality financial statements by making adjustments for earnings management or lack of comparability.
