Diverse boards in India, UK and US outperform male-only peers by US$655bn
Companies with diverse executive boards outperform peers run by all-male boards according to new research from Grant Thornton. The study, which covers listed companies in India, UK and US, estimates the opportunity cost for companies with male-only executive boards (in terms of lower returns on assets) at a staggering US$655 billion in 2014.
Although acknowledging the progress made by women at a non-executive level, the report focused on whether diverse executive teams - the people involved in day-to-day business operations - outperform male-only peers.
Analysis of the return on assets ratio (also known as return on investment) showed that, on average, companies with at least one female executive board member outperformed those with male-only boards in each of the three markets analysed.
Francesca Lagerberg, global leader for tax services at Grant Thornton, commented:
“I liken the debate around board diversity to that of renewable energy. We know it’s the right thing to do - both in terms of fairness and for sustainable future growth - but collectively society is dragging its heels. The response to both issues seems to be 'Yes, we need to take action, but it will be expensive to implement in the short-term,' so we kick the can down the road.
“But the message from our research is clear: there is a large opportunity cost for companies associated with male-only executive boards. Those businesses stuck in the past are not fully unlocking their growth potential. Like a world still addicted to fossil fuels, these companies are suffering now. A lack of action now will make it all the more difficult to respond in the future when both problems are likely to be more acute.”
In the US, S&P 500 companies with diverse boards outperformed rivals by 1.91%. In the UK FTSE 350 the gap was 0.53% and for the Indian CNX 200, 0.85%. This translates into an opportunity cost of US$567bn, US$74bn and US$14bn in each of the three markets respectively - or around 3% of GDP in the UK and US.
Francesca Lagerberg added:
“The research clearly shows what we have been talking about for a while: that diversity leads to better decision-making. We only looked at listed companies in three markets and the figures are compelling. Now imagine extrapolating the results for all companies globally.
"However, just one in ten of the companies we analysed have women board executives. I believe that organisations have not seen a clear business case for change but the work we have done articulates the advantages of diverse boards in a language that businesses will understand.
“If companies don’t instigate change then their investors will quickly become concerned they are missing out on potentially huge performance benefits. These investors need to put pressure on their portfolio companies and work with non-executive teams to progress conversations to ensure they’re taking a diligent approach to board composition.
“And finally, these findings are a prompt to governments. Business run by diverse boards are generating greater returns on the assets they employ. In an era when productivity puzzles persist and economies trade within globalised markets, facilitating female participation at a decision making level within companies might just give them a competitive advantage.”
