INTRODUCTION 1 BACKGROUND OF THE STUDY The notion of “sustainable development” started being employed at a widespread scale after being presented the Brundland report, “Our Common Future”. “Sustainable development aims to meet today's needs and aspirations without jeopardizing the ability to meet tomorrow's.” Reporting on sustainable development became a way for large corporations to demonstrate their commitment to the cause. (Carp, Mihai, Pavaloaia, Leontina, Afrasinei, Georgescu, and Iuliana, 2019). Companies respond to societal pressures by adopting sustainable reporting as a tool for validating the socially responsible behavior imposed by the external environment in which they run their business, as part of a social contract espoused by legitimacy theory. Companies also see the instrumental significance of disclosing social responsibility information in enhancing economic performance, and submit such data to improve their image and lessen the negative impact of their own actions, according to the voluntary disclosure thesis (Carp et al., 2019). Firms' transparency issues have long been a component of their daily operations. The availability of information on companies is critical for investors and other stakeholders to make good capital allocation decisions and avert any imminent hazard in our economies.(Alareeni & Hamdan, 2020). Firms aim to present a clear image of their corporate responsibility procedures and initiatives to all stakeholders. As a result, during the past two decades, corporate disclosure of environmental, social, and governance (ESG) issues has evolved in a number of ways. Furthermore, an increasing number of companies are engaging in a broad range of economic, social, environmental, and governance disclosure initiatives, and this critical subject has garnered a lot of attention (Oncioiu et al., 2020). Consumers, workers, and investors are putting increasing pressure on American firms to make substantial contributions to the greater social good, according to a recent analysis from Aflac on corporate social responsibility (CSR). According to the survey, 77 percent of customers and 73 percent of investors would be more willing to buy a company's products or services if it demonstrated a commitment to tackling social, economic, and environmental challenges. Furthermore, nearly half of respondents said firms should “make the world a better place,” compared to only 37% who said making money for shareholders is more essential(Hold, 2019). The Director General of the Securities and Exchange Commission, ‘Reverend Daniel Ogbarmey Tetteh, has stated that listed firms must prioritize sustainability reporting over profit considerations in order to protect the environment. To that aim, he urged publicly traded companies to improve their sustainability reporting in line with global disclosure requirements, emphasizing that corporate executive should take a long-term view of the business and avoid the typical short-term profit goals just for the benefit of shareholders. Mr. Tetteh, who delivered the warning during a sustainability reporting event in Accra on March 9, 2020, stated that environmental sustainability had become a significant global concern for company sustainability’. From the 25th to the 27th of September 2015, leaders of state and government and high representatives met at the United Nations Headquarters in New York to agree on a new set of global sustainable development objectives. The goal is to create balanced and integrated sustainable development in all three dimensions: economic, social, and environmental. To attain these objectives, governments are taking steps to ensure that their enterprises pay close attention to the economic, social, and environmental aspects of their operations in order to support Agenda 2030 (Sustainable Development Solutions Network, 2015). It is critical that firms operating in Ghana pay attention to economic, social, and environmental issues. Businesses must account for all parts of their operations. The majority of the environmental problems that our country, Ghana, faces are generated by the operations of these enterprises. Land degradation, mining issues, inadequate waste management and the emission of harmful compounds into the atmosphere that cause respiratory diseases in humans are all severe difficulties that our country faces. Businesses should report on their economic, social, and environmental actions as a matter of course. Firms listed on the stock exchange must seek to look beyond profit and embrace the concept of sustainability which helps to sustain every business entity. It is with this regard that, this study seeks to examine the sustainability reports of listed firms in Ghana and the impact of these reports on the firm’s value. 1.3 Statement of the problem Many researches on sustainability reporting have focused on companies in developed Asia, Europe, and the United States. The majority of studies looked at the effects of sustainability reporting on a company's profitability. Other research looked at the effect of sustainability reports on a company's growth. (Ali et al., 2019) The impact of reporting on sustainability in economic decisions made by investors using GRI indicators, as applied to banks and industry sectors listed on the Iraq Stock Exchange. The findings suggest that reporting sustainability has no statistically significant impact on investors' economic judgments. (Ching et al., 2017) verified whether the sustainability reporting quality would affect corporate financial performance (CFP) among the firms listed on Corporate Sustainability Index (ISE) and to examine the quality of information disclosed in their sustainability reports (SR). The findings were that, there was no association between accounting and market-based variables and the reporting quality, and although the quality disclosure is improving throughout the years studied, the scores are still low. (Zahid & Ghazali, 2015) examined the implementation of corporate sustainability (CS) practice by Malaysian Real Estate Investment Trusts (REITs) and property listed companies, following the three dimensional (economic, environmental, and social) framework of corporate sustainability. The content analysis indicates that the majority of companies among the sample have their social responsibility and sustainability strategies for the satisfaction of stakeholders and legitimizing firm practices. Meanwhile, the crucial question firms and shareholders must answer is whether sustainability disclosure practices can be turned into positive firm performance. Prior research has tried to test the effect of sustainability disclosure practices on firm performance. (Mensah, 2019) sustainability disclosure issues are interconnected; therefore, considering only one dimension could be problematic. A limited number of sustainability disclosure studies focus on all three dimensions of sustainability reporting and their impact on performance in a single setting more important, the findings of these studies include conflicting perspectives and inconclusive findings on whether sustainability disclosure and its dimensions have a positive, negative or neutral impact on firm’s performance. Therefore, it is essential to focus on all dimensions of sustainability reporting when testing their impact on firm performance. The study will contributes to sustainability reporting prior literature by examining the developments and improvements in sustainability reports disclosures of listed firms on the Ghana stock exchange. The study will evaluate firms’ performance based on three dimensions: the firm’s financial, operational and market performance indicators, return on equity (ROE), return on assets (ROA) and the Tobin’s q. The study will also incorporate the influence of board characteristics on sustainability reports of listed firms on the Ghana stock exchange. 1.4 objectives of the study The general objectives of the study will be to analyse sustainability reports and firms value of listed firms on Ghana stock exchange market. However the following will be the specific objectives: i. To examine sustainability reports of listed firms on the Ghana stock exchange ii. To assess the impact of sustainability reports on the value of firms listed on the Ghana stock exchange. iii. To identify the influence of board characteristics on sustainability reports of listed firms on the Ghana stock exchange. 1.5 Research questions Answers to the following research questions will be sought to achieve the objectives of the study. i. What are the factors that affect sustainability reports of firms listed on the Ghana stock exchange? ii. What are the impacts of sustainability reports on the value of firms listed on the Ghana stock exchange? iii. To what extent do board characteristics influence sustainability reports of firms listed on the Ghana stock exchange? Literature review Businesses nowadays operate in a global dynamic environment. At the same time, today’s dynamic business environment encounters certain threats, which are needed to be addressed and controlled for the sake of stakeholders’ protection and future generations (Hongming et al., 2020). These issues cannot be compromised as organizations are socially responsible for sustainability impact and environ- mental issues, because the entire corporate world depends on these resources to operate. Unlike financial reporting, sustainability reporting is voluntary in most countries (Zelazna et al., 2020). For this reason, most companies presenting information about social and environmental protection actions use voluntary reporting systems, such as the guidelines in the Global Reporting Initiative (GRI) and in recent years, the integrated reporting developed by the International Integrated Reporting Council(GRI et al., 2021) . Although efforts were made toward standardizing the information regarding sustainable reporting (GRI ), there are still differences in the content and quality of reports compiled. The lack of compulsoriness and standardization in this field leads to inconsistencies in the companies’ assessment and reporting of sustainability(Hahn & Kühnen, 2013). This vulnerability is also generated by the fact that, unlike financial statements, no certification is required for these reports. Greater transparency and accountability, as insisted upon by a larger set of stakeholders, have now become essential requirements for corporate success. Corporate sustainability has become an integral part of corporate life and corporate strategy(Aras & Crowther, 2008) and is of paramount importance in creating a transparent environment within the business. In this context, SR is acknowledged as an important practice that contributes towards fulfilling stakeholders’ diverse demands (Genoud & Vignau, 2017). Study made by (Xinwa, 2018), theorized through the supply and demand model that investing in initiatives such as social and environmental issues maximize the market value of the company. Despite those findings, companies are still reluctant to invest in such initiatives. The role of stakeholders such as employees, shareholders, customers and environment becomes more and more important for the sustainability of organizations. In the mid-1980’s a stakeholder approach emerged due to rising concerns of managers who were facing turbulences and changes in their environment. Traditional strategies framework were not providing any help to understand the phenomena and to find out solutions; there was a need for a new framework (Genoud & Vignau, 2017). ‘Freeman stated in his book in 1984 that “Our current theories are inconsistent with both quantity and kinds of change that are occurring in the business environment of the 1980’s… A new conceptual framework is needed” (pg. 5). Hence, the stakeholder theory became a solution. However, the idea of a stakeholder approach was not entirely new. Indeed, pioneers from the Stanford Research Institute engaged research in the 1960’s to elaborate this stakeholder approach. They argued that it was necessary for firms to consider the concerns of every stakeholder and not only the shareholders, for a long term success. At the time when they were using the word stakeholders, they were already referring to customers, employees, suppliers, lenders and society(Saleh et al., 1989). This development had a small impact on managerial theories at the time but became a management practice decades afterwards thanks to further studies such as Freeman’s book. The stakeholder approach, developed by Freeman, explored the concept of strategic management surpassing its original economic stand by considering stakeholders as “any group or individual who is affected by or can affect the achievement of an organisation’s objectives”. The 21st Century is the century of “Managing for Stakeholders”. Subsequently, the stakeholder theory is of significant importance in our study since a natural fit exists between the concept of sustainability reports and company’s stakeholders. THEORETICAL FRAMEWORK Stakeholder theory (N. Burhan & Rahmanti, 2012) Stakeholder theory has both an ethical (moral) or normative branch and a positive (managerial) branch. The moral (normative) perspective of Stake- holder Theory argues that all stakeholders have the right to be treated fairly by a business entity, and the issues of stakeholder power are not directly relevant. Management of the business organization should be for the benefit of all the stakeholders. Within the ethical (moral) or normative perspective of Stakeholder Theory, all stakeholder have certain rights that must not be violated. It can be acknowledged that this concept can be extended to a notion that all stakeholders also have a right to be provided with information about how the business entity’s operation affects them(Yu & Zhao, 2015). Non-financial corporate performance has begun to capture the attention of increasing number of investment professionals as they realize that profitability alone is not sufficient for a firm’s longterm growth. By looking beyond economic, strategic and operational factors to include environmental and social considerations, sustainability reporting helps boost corporate transparency, strengthen risk management, promote stakeholder engagement and improve communications with stakeholders (Loh,Lawrence,thomas, Wang and Yu 2017) . Companies are also largely accountable for the impact of their activity on the community. However, it is often difficult for external stakeholders to assess the actual sustainability performance of the company. Therefore, to minimize information asymmetry between companies and their stakeholders, companies are expected to comply with sustainability transparency standards. Accordingly, sustainability and corporate social responsibility reports have become a major theme in management and accounting. (Khaghaany et al., 2019) As the number of sustainability reports continues to grow, global companies are announcing their efforts to enhance their environmental and social performance, known as sustainability, and to meet growing pressure to do more to promote environmental and social responsibility. Companies are therefore developing new communication methods and attempting to integrate sustainability in strategic performance measurement systems(Tempero, 2019). Legitimacy theory (N. Burhan & Rahmanti, 2012) states that legitimacy theory asserts that organizations continually seek to ensure that they operate within the bounds and norms of their respective societies, that is, they attempt to ensure that their activities are perceived by outside parties as being legitimate.(Cuganesan et al., 2007) Legitimacy theory relies upon the notion that there is a “social contract between the entity and the society in which it operates. The theory is used to explain the expectations that society has about how entities should conduct their operations. Legitimacy theory emphasizes that the business entities must consider the rights of the society at large, not only those of its investors(Gibassier & Unerman, 2021). Failure to adhere to societal expectations may lead to sanctions by the society. With respect to legitimacy theory, business entities would voluntarily report their activities if management deems it right that those activities were expected by communities in which it operate(Burlea-schiopoiu & Popa, 2013). Sustainability disclosure is a response to pressure exerted upon firms to conduct their activities in a way acceptable to the society ((Shamil et al., 2014). Among the theories adopted to explain sustainability disclosures, the legitimacy theory has been found to be the most successful (Vitolla & Rubino, 2017). Legitimacy theory extends the principal-agent relationship to include a wider group of stakeholders representing societal interests, and this conceptualization broadens the role of corporate governance mechanism to align firm activities with the wider interest of stakeholders(Ayuso & Argandoña, 2009). Thus, managers are motivated to disclose more information to support their claim on legitimacy. Firms value To satisfy the growing information requirements of stakeholders who look for it in firms’disclosure reports, the emphasis has to be placed on the usefulness, relevance and, value of the information contained within those reports ((Swarnapali, 2019)) value relevance is an ongoing theme in accounting and finance literature. Firms reports on sustainability because it is acknowledged that such activities when communicated through corporate sustainability reports lead to sustainable competitive advantage(Peters & Simaens, 2020). Corporate sustianability provides various benefits to the firm. For instance, making investments in firms sustainability activities may help the firm in developing capabilities and resources(Camilleri, 2017). These capabilities and resources related to corporate culture and technical know-how, which are acquired internally, can eventually lead to more efficient utilisation of resources. Such investments may also lead to the creation of various essential intangible resources which are mostly associated with employees. Firm’s image is one of the fundamental intangible resources that lead to competitive advantage. Firms with a better Sustainability image are able to develop and maintain a healthy relationship with investors, suppliers, bankers, customers and competitors (Laskar & Gopal Maji, 2018) Through corporate sustainability report, firms are able to attract and retain better employees and enhance employees’ motivation, as well as their loyalty and commitment towards the firm, which, in turn, improves firms’ profitability and value(Strandberg, 2009). In the long run, sustainability report brings better benefits by reducing the cost of conflicts with stakeholders and ensures a healthy relationship with them. It also helps in building a reputation and enhances firm’s productivity(Jiao & Xie, 2013). These better corporate sustainability practices are subject to more predictable earnings and lower the risk for investors and economic uncertainty(Endris, 2008). Firms get the benefit of corporate sustainability from the market only when corporate sustainability activities are communicated in the form of a report (Michelon et al., 2015). In order to derive these benefits, CS reporting has become a necessary requirement for entering the market. Board size Extant literature on board size suggests two contrasting views. One view argues for larger boards and the other view argues for smaller boards. The first view argues that larger boards are inefficient because they result in weaker control of management and increases the agency cost. However, this view is countered by stating that large boards are less likely to be influenced by management(Hidayat & Utama, 2015). Although small boards are considered efficient they are likely to be influenced by managers. Furthermore, it is argued that large boards allow including directors with different expertise(García Martín & Herrero, 2018). Previous studies have found a positive association between board size and voluntary disclosures. Similarly, studies exploring the association between board size and sustainability disclosures have reported a positive association ((Shamil et al., 2014). Data and methodology Study design A qualitative and quantitative approach will be used to achieve the objectives of the study. Sample Size The study covers companies listed on the Ghana stock exchange. The total sample size will be 32 amongst which companies that do not report on sustainability are excluded. Data collection procedure The researcher’s Sources of data will be derived from the annual report of listed firms. Data for this research is secondary data. For sustainability reporting and firm status, all information the researcher will consider is publicly available, of which major sources are the annual reports and sustainability reports or equivalents if applicable. In this study, sustainability reporting refers to the disclosure of non-financial information, including aspects such as governance, economic, social and environmental. We will take information disclosed by companies’ from 2008 up to 2018 into account. Sustainability practices of companies disclosed on their corporate website, standalone sustainability report, and/or in the annual report are considered. Data pertaining to board characteristics will also be collected from the annual reports of the listed firms. Data Analysis Panel data, sometimes referred to as longitudinal data, is data that contains observations about different cross sections across time. Examples of groups that may make up panel data series include countries, firms, individuals, or demographic groups. There are number of advantages of panel data: Panel data contains more information, more variability and more efficiency than pure time series data or cross-sectional data. Panel data can detect and measure statistical effects that pure time series or cross-sectional data can’t. To summarize, explain, and investigate trends in the acquired data, the researcher will employ descriptive statistics. The study topics will next be tested using panel data multiple regression analysis. Multicollinearity tests are also performed to confirm that the variables are not correlated. Fixed effects (FE) models and random effects (RE) models are the two basic modeling strategies used to evaluate panel data (Dougherty, 2011). Unlike FE models, RE models presume that differences between entities are random and unrelated to the independent variables in the model (Gujarati and Porter, 2009). Measurement of financial performance The financial performance will be comprised of return on asset (ROA), return on equity (ROE), stock price ratio and Tobin's q, all of which are in line with past research. (Oware & Mallikarjunappa, 2020). The return on assets (ROA) is the ratio of net income to total assets. The choice of ROA has an impact on a company's ability to replace fixed assets. (Oware & Mallikarjunappa, 2020). ROE is the net income over shareholder equity and it measures how a firm uses shareholders’ funds to generate profit.(Oware & Mallikarjunappa, 2020). It is calculated as ROE net income /total equity multiplied by100 where net income is net profit after tax and total equity is the shareholders fund. The study will use stock price ratio (SPR) as a variable indicator for measuring firm performance. SPR = current stock price divided previous stock price multiplied by 100%. Other studies have used this variable and mostly show a positive sign(Oware & Mallikarjunappa, 2020). The study also sought to measure the reaction from shareholders from the stock market. Tobin’s q measures firm value. Tobin’s q = (market value of equity + book value of total liability/ total Asset. Board characteristics Board size will be one of the study's independent variables and board independence, because board size and firm size have been found to have a positive link, and firm size is commonly evaluated using the natural log of total assets, board size will be assessed by the natural log of number of directors in this study (Alshetwi, 2017).
