The OECD is partway through a process of updating its Principles of Corporate Governance document. The current document dates from 2004. In the decade since, much about the way boards could, should or actually do work seems to have changed (although whether business performance has improved as a result of these changes remains an open question!), so an update makes good sense. A public consultation process opened on 14 November. It remains open until 4 January 2015.
The link to the OECD's call for submissions is here. I intend to make a submission and encourage you to do so  if you are knowledgeable of corporate governance, board practice and business performance matters. The submission address is dafca.contact@oecd.org.
