The Conference Board’s report: “How Board Diversity Can Contribute to Board Effectiveness” documents board diversity disclosure trends by index (S&P 500 and Russell 3000) and characteristic, inclusive of gender, race/ethnicity, and sexual orientation. Data was derived from companies’ most recent SEC filings or publicly accessible governance and other documents. The report, which was produced in collaboration with data analytics firm ESGAUGE, along with Debevoise & Plimpton; KPMG; Russell Reynolds Associates; and the John L. Weinberg Center for Corporate Governance, also offers some atypical insights about how to frame and consider the board diversity discussion from board members, governance professionals, and C-suite executives.
