A diverse board means diverse perspective and increased social acceptability, ensuring that the board conducts itself appropriately.
It is important for companies in Singapore to challenge the traditional ways of sourcing directors (that is, through personal networks), and focus on acquiring skills, experiences and a diversity of thought.
DIVERSITY on boards and management teams is increasingly and deservedly gaining prominence in Singapore. Organisations such as the newly established Council for Board Diversity and Singapore Institute of Directors' Diversity Committee are championing more diverse representation on boards across the public, private, and charity sectors. Their tireless efforts have resulted in a considerable improvement in the number of female non-executive directors (NEDs) within the top 100 companies listed on the Singapore Exchange (SGX), growing from 7.5 per cent in 2013 to 15.2 per cent last year. However, there is still a long way to go in achieving the stated targets of 20 per cent by 2020, and 30 per cent by 2030.
Board diversity is often viewed as a societal issue. Half of our society and half our workforce are women, so it makes sense that the board and management teams should also have stronger representation of women.
Enlightened companies and board chair view gender diversity as something more than a societal issue - they see it as the right business decision as well. These companies understand that women directors bring different skills, attributes and stewardship styles to the board, which ultimately enhances its effectiveness.
We should also understand that gender is just one dimension of diversity. In the context of board diversity, it will be meaningful to expand the definition of diversity to cover board independence, as well as age, tenure, ethnicity and domain expertise.
In a recent study, Willis Towers Watson conducted research to assess the importance of board diversity and business performance of companies in Singapore. Through empirical analysis, we found that companies with more diverse boards generate stronger business results.
Our hypothesis was that high-performing companies with a diverse board are higher-performing financially than companies without a broadly diverse board. Having NEDs with a diverse mix of skills, experiences and expertise ensures that probing questioning, constructive criticism and challenging debate can take place. The resulting decisions will be based on varied perspectives, and in turn, will have higher success rates.
We analysed the top 100 SGX-listed companies and tested the relationship between board diversity and the companies' latest three-year financial performance measured as revenue growth, profit growth, company valuation measured as price-to-earnings ratios (P/E), return on equity (ROE), economic value add (EVA), and total shareholders returns (TSR).
- Independence: Boards with a majority of independent directors should have unbiased decision-making aligned with shareholders' interests. Independent board members can bring external expertise, which can reduce agency costs and improve performance. However, they may also operate at an information disadvantage and may lack institutional history, thus limiting their effectiveness.
Consequently, our hypothesis was that there ought to be a positive relationship between a board with a majority of independent members, and company performance. Based on our study, companies which had a board with 75 to 90 per cent independent directors tended to have the strongest performance, compared with those with fewer independent directors. At less than 10 percent of the overall sample, these companies had higher TSR, ROE, P/E ratios and EVA performance than those with fewer independent directors.
This corroborates the principle that boards with the optimal balance between independent and non-independent representation are likely to outperform all others.
- Gender: Women often bring different competencies and approaches to stewardship, different risk-reward orientations, and consequently may provide more balanced perspectives to decision-making. Female board members may also be able to represent the views of the wider employee base, and hence lead to enhanced understanding of broader customer preferences.
Nearly a third of the companies in our study had no women directors. Companies with at least one female on the board out-performed in terms of TSR, ROE and revenue growth. Companies with two or more female directors also out-performed those with no female directors, but did not see a material upside compared to those with one female director. Boards with two or more female directors were valued at a premium (that is, higher P/E ratios).
This supports the hypothesis that companies with at least one female director have stronger business performance.
- Age: The 2018 revision of Singapore's code of corporate governance, for the first time, called out age as an important attribute of board diversity. The premise is that directors of different age groups bring different life experiences and perspectives to the board, enhancing its decision-making effectiveness.
Our analysis shows that only around 2 per cent of NEDS within the top 100 Singapore listed companies are below the age of 40 years old, and around 2 per cent are above the age of 80. However, our study revealed that the age of directors did not have any material correlation to company performance. Instead, there was a strong relationship between company performance and age differential among board members.
Companies with at least one generation difference - with between 20 and 35 years separating the youngest and oldest director - tended to outperform in terms of ROE, P/E ratio and revenue growth.
This emphasises the importance of younger directors who can bring fresh ideas, as well as older directors who often offer a wealth of experience.
- Tenure: Routine turnover and board refresh is necessary to introduce new ideas, experiences and to keep up with the dynamic needs of the business. This is particularly relevant in Singapore, where the revised Code sets a nine-year term limit beyond which a director may not be considered independent.
We analysed the correlations between different average NED tenures and company performance, and the findings were inconclusive. However, similar to findings for age diversity, our research shows that companies with a tenure spread of more than eight years exhibited higher TSR, EVA and revenue growth.
This supports the principle that having board members with varying lengths of tenure provides diverse perspectives, and a healthy balance between fresh ideas and institutional knowledge, presumably leading to more measured decision making, and consequently stronger company performance.
- Ethnicity: Greater ethnic diversity on boards should bring stronger inclusiveness, creativity and acceptance to innovative ideas, which may improve strategic decision making. And similar to gender diversity, ethnic diversity may allow the board to better understand and consider the company's employees and customers. The hypothesis is that an increase in the number of ethnic minorities may lower barriers to interaction, allowing for a wider range of skills and perspectives to be shared. To this effect, we tested whether a higher proportion of ethnic-minority board members would result in better company performance.
Our analysis suggests that about two-thirds of the top 100 companies do not have ethnic diversity on the board and are culturally homogeneous. However, there is no conclusive evidence to suggest that culturally diverse boards result in stronger financial performance. It is interesting to note though, companies with ethnically diverse boards had an around 10 per cent higher P/E multiple.
This shows a positive relationship between ethnic diversity in the board and the firm's reputation, and in turn, its valuation.
- Expertise: One of the more important traits of diversity is the variety of domain expertise of board members. A majority of the board members in Singapore tend to have accounting / audit, legal, or commercial (that is, P&L management) backgrounds. However, our hypothesis was that a broader range of expertise (for example, technology, risk, human capital, organisational development, marketing and public relations) would provide more domain knowledge to the board's decision making, leading to stronger company performance
Our analysis suggests that only 20 per cent of NEDs within the top 100 companies had experience other than accounting, legal, or commercial. The findings reveal that companies with directors that have at least four areas of domain expertise perform better in terms of TSR, ROE, P/E ratio, EVA and revenue growth. Interestingly, companies which had five or more functional skills represented within their NEDs saw a 28 per cent higher valuation premium.
This highlights that companies with directors who have multiple functional disciplines and are able to provide varied domain expertise to the board's proceedings will performmore strongly.
The analysis of the top 100 Singapore listed companies illustrates a strong relationship between board diversity and company performance. Nomination committees should critically review their board compositions and work towards achieving more diverse representation on boards, such that:
- A majority of directors should be independent, balanced by at least one non-independent director (usually the CEO and MD);
- There should be at least one female NED, but ideally two or more - and eventually there should be equal representation;
- At least one director should be below the age of 40 or 45 years old to provide a generational difference between the youngest and oldest director;
- Boards should have a strong spread of tenures with eight years or more between the newest and oldest serving board member, even if that means that some directors exceed the nine-year rule and may no longer be deemed independent;
- At least one board member should come from a cultural minority;
- Directors should represent at least four functional expertise areas such as audit and accountancy, legal backgrounds, human resources, risk management and technology
It is important for companies in Singapore to challenge the traditional ways of sourcing directors (that is, through personal networks), and focus on acquiring skills, experiences and a diversity of thought. Boards may fail tomorrow if they fail to change today. Progressive companies are beginning to appreciate the importance of diversity, and have tailored their nomination and appointment priorities accordingly.
In a diverse society, a diverse board can provide multiple perspectives, helping increased social acceptability and, in turn, ensure that the board conducts itself appropriately. It is critical for boards to ensure they have diversity of experience, background and thought.
Indeed, the numbers speak for themselves; the business case for board diversity is irrefutable.
