corporate governance - best practices?

Should the CEO and the Chairman be the same person? Or shoul the Chairman be an independent board member?

CEO and chairman should be different. And it is not necessary that Chairman should be an independent board member. It is recommended though.

It is not required that “CEO and Chairman” be different. It is recommended though. A company would not violate CFAI corp governance standards by having same CEO and Chairman. It is not necessary that the Chairman be an independent board member.
