Abstract

This research note aims to enrich our understanding regarding the market valuation implications of financial reporting under an Integrated Reporting (IR) approach. In order to do so, we focus on the Johannesburg Stock Exchange (JSE) and we examine whether the value relevance of summary accounting information (i.e., book value of equity and earnings) of firms listed on the JSE has enhanced after the mandatory adoption of an IR approach under the King III Report. Our study can be seen as a response to the recent calls for a closer investigation of the usefulness of the new reporting trend for investors. More specifically, our study can be seen as a response to the stance taken by the International Integrated Reporting Council (IIRC) Framework that the adoption of an IR approach improves the usefulness of financial reporting for investors. For our empirical tests we utilize a sample of 954 firm-year observations and employ a linear price-level model which associates a firm’s market value of equity with its book value of equity and earnings. In line with the IIRC Framework’s expectations, we find strong evidence of a sharp increase of the earnings’ valuation coefficient. However, contrary to the Framework’s stance, our results indicate a decline in the value relevance of net assets. Such a decline may be imputed to risks and/or unbooked liabilities that are revealed or measured more reliably after the introduction of an IR approach on the JSE. It should be noted, however, that despite its cause, the decline in the value relevance of net assets can be seen as a further argument in favor of the IIRC stance to assign equal importance to a wide range of “capitals,” such as human, social and natural capital. We believe that our findings are of particular interest to a wide range of regulators, standards setters, practitioners, and academics but first and foremost to the JSE and IIRC.
