What a governance code sets out
Launch library · evergreen read

A governance code sets out recommended practices for how a company should be structured and run, covering areas such as board composition, committee structures, and disclosure expectations. Many codes operate on a comply or explain basis, letting a company depart from a recommendation provided it explains clearly why it has chosen to do so.
This flexible approach reflects a recognition that a single rigid structure will not suit every company equally well, while still creating meaningful pressure toward good practice, since investors and analysts can readily see exactly where a company has departed from the code and judge whether its stated explanation is genuinely convincing.
Over time, governance codes tend to be revised as expectations shift, often in response to a high profile governance failure that exposes a gap the existing code did not adequately address. A code, in this sense, functions less as a fixed rulebook and more as a living, gradually evolving standard.
