Corporate governance

UK listed companies are required to include a statement in their annual reports detailing how they apply the principles, and comply with the provisions of the Combined Code.  Some of the main provisions are as follows:

  • Every company should be headed by an effective board
  • The board should have a balance of executive and independent nonexecutive directors
  • The board should maintain a sound system of internal control to safeguard shareholders' investments and the company's assets

For non-UK companies, financial information may be presented in accordance with IFRS as adopted by the EU or equivalent standards (currently US GAAP and Japanese GAAP).  There are also modified corporate governance requirements for non-UK companies with a primary listing, such as disclosure of:

  • whether or not the company complies with the corporate governance regime of its country of incorporation
  • The significant ways in which its corporate governance practices differ from those set out in the Combined Code.
