Hey board meetings can mean a phone call, video conferencing, etc. Everyone does not necessarily meet. Ballmer can do a Skype call or Nokia can. He can pick up the phone and call Bill Gates Chairman of the Board, etc. See proof of this before and you will see what I mean. A meeting may be in 1 minute or 10 days and not in person.
To facilitate participation at the Board meetings, directors may attend in person, via telephone conference or via video-conference.
