Executive Directors


Board of directors

The board has six standing committees (Audit; Social, ethics and transformation; Risk; Remuneration; Nominations and Acquisition committees) with delegated authority from the board. Each board committee is chaired by an independent non-executive director.

Diversity, in its broadest sense, is the hallmark of the Bidvest board, something we are very proud of. The non-executive directors are all independent and represent 75% of the board.
