The first formal corporate governance code was the Cadbury Report (1992) in the United Kingdom.

It established principles of good corporate governance, emphasizing board effectiveness, accountability, and audit transparency.

The U.S. Sarbanes-Oxley Act (2002) and Germany’s Corporate Governance Code (2002) came much later.

The Cadbury Report influenced global corporate governance frameworks, including OECD Principles of Corporate Governance and the G20 Corporate Governance Code.
