2025 Singapore Board Diversity Index Overview

The document is a technical report detailing the 2025 Singapore Board Diversity Index (BDI), developed by WTW in collaboration with the Singapore Institute of Directors (SID) and James Cook University (JCU). The BDI aims to assess and highlight the state of board diversity among Singapore-listed companies across various dimensions. The report outlines the importance of cognitive diversity on boards and emphasizes that personal and experiential diversity are essential for fostering diverse thought and experience. It presents an analysis of 553 companies listed on the SGX and Catalist, examining eight key attributes of board diversity, including gender, age, tenure, independence, culture, international experience, domain knowledge, and industry expertise. The report also acknowledges the contributions of various partners in the data collection process and clarifies that the BDI is not prescriptive regarding ideal board composition, nor does it claim a direct link between diversity and corporate performance.
