Parmi Natesan, executive: centre for corporate governance at the Institute of Directors in Southern Africa (IoDSA), says, “There are no easy answers but there are warning signs boards should look out for.
“CEO performance has a direct link to company performance, which is why best practice around appointing, overseeing and evaluating the CEO is contained in King III. Putting a CEO succession plan in place, and initiating it at the right time, are key strategic considerations a board must take.”
Boards do have some research to help them. One study, by researchers at the Fox School of Business at Temple University, shows that CEOs go through discernible phases, which can help boards identify CEOs heading close to the danger zone. In their early years of tenure, CEOs tend to learn rapidly and take risks, moving onto sponsoring new initiatives and acquiring new skills. Over time, though, they tend to turn inwards, becoming risk-averse and relying overmuch on experience and possibly obsolete paradigms.
The Temple study found that the optimal CEO tenure was 4.8 years, a figure backed up by Fortune magazine’s finding that the 500 largest US companies have a median CEO tenure of 4.9 years. A wider-ranging sample of companies in another study showed variances in median CEO tenure from year to year, possibly linked to economic cycles.
A key factor to be borne in mind is the rapid change in the business environment, even the most highly skilled CEO could find his or her skillsets inadequate as time goes by. In addition, CEOs can damage their own reputations by staying too long at one company as opposed to exiting on a high note.
“Clearly, boards have to exercise their judgement — one can’t just act by rote and remove a CEO after a certain number of years but based on the research and accumulated experience, boards should look out for five warning signs.”
