They do not need a reason to dismiss the board, a majority vote suffices. The shareholders own the company, so they can install whatever board they like for whatever reason they like. I'm not aware of any board that got dismiseed for not aggressively optimizing taxes. Similarily, shareholders rarely complain about philantropic programmes of large corporations, for example this: http://www.exxonmobil.com/Corporate/community.aspx

Thanks.

Let's be honest, if Facebook decided to give back their $430 million tax credit and pay 40% on their $1.1 billion of profit, their share price would take a major dive.

Do you think the board would not be dismissed?

(Same goes for Apple, Google, etc. etc.)

Probably not since I think Zuckerberg et al controls the board.
