Considering that the Johannesburg Stock Exchange (JSE) has enacted in its Listings Requirements, compliance of listed firms to International Financial Reporting Standards (IFRS) and King Code of Good Corporate Governance, this study aims to investigate the impact of internal corporate governance attributes on the value relevance of accounting information in South Africa.

The fixed effect generalised least squares regression is used for the period from 2002 to 2014. Proxies for internal corporate governance are the size of the board, leadership structure, board activity, staggered board, boardroom independence, presence of key committees and board gender diversity. Value relevance is measured using the adjusted R² derived from a regression of stock price on earnings and equity book values by following Ohlson’s accounting-based valuation framework.

The findings suggest that the net asset value per share is value-relevant in South African listed firms and also when the boardroom is largely independent. The value of earnings per share (EPS) is more robust when corporate governance structures, such as separating the roles of chief executive officer and chairperson, proportion of board-independent board members and presence of board committees, are in place. This suggests that EPS favours agency and resource dependence theories.

The value relevance of accounting information in the South African financial market underscores the importance of requisite rules and supervision regarding financial reporting to allow asset owners and managers in the allocation of capital decisions. This study supports the view that corporate governance plays a key role in ensuring, amongst others, credible financial reporting. The outcome of this study could inform the JSE to enforce, even stricter, compliance with IFRS and corporate governance to improve the value relevance of financial information.

Significant corporate governance reforms around the world suggest that regulators and policy makers consider corporate governance as a pertinent tonic in ensuring, amongst others, credible financial reporting. The implications of the study might assure users of financial information of how compliance to corporate governance practices may influence the value of the firm. This paper provides empirical evidence in the South African context that EPS, unlike net asset value per share, is driven by corporate governance structures.

The period of this study is unique, because it covers a relatively stable economic period before the financial crisis, a challenging and unstable period of time when the financial crisis materialised, and the aftermath of the financial crisis. In addition, the examination period of the study also covers the two corporate governance reforms in South Africa, King II in 2002 and King III in 2009, as well as the new Companies Act No. 71 of 2008. These exogenous factors may influence the results.

This study aims to investigate the impact of the macroeconomic environment on South African industrial sector returns.

Using standardized coefficients derived from time-series factor models, the authors quantify the impact of macroeconomic influences on industrial sector returns. The authors analyze the structure of the resultant residual correlation matrices to establish the level of factor omission and apply a factor analytic augmentation to arrive at a specification that is free of omitted common factors.

The authors find that global influences are the most important drivers of returns and that industrial sectors are highly integrated with the global economy. The authors show that specifications that comprise only macroeconomic factors and proxies for omitted factors in the form of residual market factors are likely to be underspecified. This study demonstrates that a factor analytic augmentation is an effective approach to ensuring an adequately specified model.

The findings have a number of implications that are of interest to investors, econometricians and researchers. While the study focusses on a single market, the South African stock market, as represented by the Johannesburg Stock Exchange (JSE), it is a highly developed and globally integrated market. In terms of market capitalization, it exceeds the Madrid Stock Exchange, the Taiwan Stock Exchange and the BM&F Bovespa. Yet, a limited number of studies investigate the macroeconomic drivers of the South African stock market.

Investors should be aware that while the South African domestic environment, especially political risk, has an impact on returns, global influences are the greatest determinants of returns. No industrial sectors are insulated from global influences and this limits the potential for diversification. This study suggests an alternative set of macroeconomic factors that may be used in further analysis and asset pricing studies. From an econometric perspective, this study demonstrates the usefulness of a factor analytic augmentation as a solution to factor omission in models that use macroeconomic factors to proxy for systematic influences that describe asset prices.

The contribution lies in providing insight into a large and well-developed yet understudied financial market, the South African stock market. This study considers a much broader set of macroeconomic factors than prior studies. A methodological contribution is made by estimating and interpreting standardized coefficients to discriminate between the impact of domestically and internationally driven factors. This study shows that should coefficients not be standardized, inferences relating to the relative importance of factors will differ. Finally, the authors unify an approach of using pre-specified factors with a factor analytic approach to address factor omission and to ensure a valid and readily interpretable specification.

This paper aims to test the effects of financial reforms on the structural stability of the parameter estimates in the determinants of capital structure.

A panel of 100 non‐financial companies listed on the Johannesburg Stock Exchange is constructed, and a panel least squares estimation technique is used to test for lagged, current and leading structural breaks in the firm specific determinants of leverage.

The results show that structural reforms have a significant role in influencing the empirical relationship between leverage and its determinants. Specifically, the lifting of international sanctions and stock market liberalisation have a significant impact on the stability of the profitability, growth and tax rate variables for the book and market values of the debt to equity ratio. Furthermore, when the total and short term debt ratios are considered, only stock market liberalisation appears to have a significant influence on the stability of the profitability parameter.

This paper adds to the existing body of literature on capital structure by documenting the extent of structural breaks in the parameter estimates of the relationship between leverage and firm specific determinants of capital structure for listed non‐financial firms in South Africa.
