Enterprise risk management (ERM) has emerged as a distinct model for managing a sophisticated portfolio of corporate risks. The purpose of this study was to determine the impact of ERM on firm value for companies on the Johannesburg Securities Exchange. The sample comprised forty-five firms from different industries over the period 2000-2016. Most studies used five or ten-year periods, using data derived from only one industry. Tobin’s Q was used as a proxy for firm value. Multivariate regression analysis was employed to determine statistical relationships. The findings indicate a significant correlation between ERM and Tobin’s Q, indicating that ERM significantly contributes to firm value. These findings may be used to develop and shape ERM policy frameworks for firms and countries. The study provides new insights, from an African emerging market context on the value effects of ERM. Larger and international samples may improve future studies. / Business Management / M. Com. (Business Management)
