Corporate governance CEO and chair

If the CEO of the company is chair of Board of directors, what do you think of corporate governance? and if other officials are member? Thanks

Best practice is for CEO and Chair to be separate people. Best practice is that 75% of the board is independent.

having the CEO as the chairman is considered bad practice. 75% of the board should be independent. as far as “other” officials, more detail is needed to assess the appropriateness
