The LME Board of Directors is responsible for providing leadership, either directly or through its committees, to deliver long-term value to shareholders and other stakeholders.
It also retains overall responsibility for the management of the London Metal Exchange (LME). It establishes corporate policies, sets strategic direction, ensures that an effective internal control environment is in place, and oversees the management which is responsible for day-to-day operations.
The Board however recognises that delegating its functions and authorities to its committees and the management does not absolve its overall responsibility for the sound governance.
