This study seeks to evaluate the shareholder wealth effect of corporate name change by Malaysian listed companies. Our sample comprises both failed and non-failed Malaysian companies and standard event study methodology is employed. Our results indicate that corporate name changes have no impact on shareholder wealth unless the announcement is accompanied with news of approved corporate restructuring by Malaysian regulatory authorities. In addition, extraordinary abnormal returns were found on the announcement day for the failed companies group whilst, the sub-sample of non-failed companies experienced a significant low negative abnormal return around the announcement date indicating disapproval of cosmetic name changes. Investors in Malaysia are generally cautious about receiving news of a corporate name change. The study also suggests that the market cannot be fooled by mere name change; such a change must be backed by serious efforts towards recovery.

AbstractEnsuring access to clean water is one of the most important development and health challenges of the twenty-first century. Given the manifold impacts of business activities on water resources, corporate water actions should be of central concern to business ethics researchers. Yet so far we know too little about whether business activities that impact on water resources are noticed or how corporate water actions are valued by a firm’s stakeholders, including by financial markets. In response, we conduct an event study to investigate the shareholder wealth effect of reports of corporate water actions. We explore stock market reactions to water actions by S&P 500 firms from 2005 to 2017, showing that the market reacts positively to reports of responsible water actions and negatively to irresponsible actions. We further explain that these abnormal returns to water actions are associated with a firm’s past performance on ethical issues, arguing that the reputational effects from prior corporate social responsibility and irresponsibility influence market reactions. Our analysis provides evidence that there are diminishing marginal returns to responsible water actions for firms with records of past responsibility and an offsetting effect for those with past irresponsibility. Similarly, we demonstrate an insurance effect that limits punishment for irresponsible water actions for firms with responsible performance records and diminishing negative marginal returns for those already seen to be irresponsible. This study is the first to show that shareholders recognize market value in corporate water actions and are prepared to award or punish firms in stock markets based on their impacts on water.
