There! That's the kind of info I was after, thanks. Interesting trend for "staggered boards" (taken from Wikipedia): The Wall Street Journal reported in January of 2007 that 2006 marked a key switch in the trend toward declassification or annual votes on all directors: more than half (55%) of the S&P 500 companies have declassified boards, compared with 47% in 2005.
