The impact of board structures on intellectual capital performance in South Africa: An empirical investigation

Abstract

The well documented agency problem remains an ongoing debate, with the board as a central point of corporate governance providing a control mechanism. The effective composition and functioning of the board is therefore highlighted as being key to overcoming agency‐problems (Hermalin and Weisback, 2003; Adams and Ferreira, 2009). This research report explores the relationship between the structural aspects of the board, including the average age of board members, the size of the board of directors and the specific positions women and ethnic persons hold on the board of South African listed companies, and intellectual capital performance measured using VAIC™ (Pulic, 2000), as well as market adjusted share returns. The population consists of all South African companies listed on the JSE Securities Exchange during 2011 with the final sample consisting of 193 companies after transformation of the data. The results of the regression analyses indicated no significant relationship between intellectual capital performance and board size, or specific positions being held by women or ethnic persons. A significant positive relationship however exists between the average age of the board of directors and intellectual capital performance. As a result, companies may be able to enhance their intellectual capital performance by increasing the average age of their board members.
