Berkshire Hathaway
long a rarity among big companies because it doesn’t emphasize diversity for its board, wants its directors to put a sizable chunk of their money in its shares.
Instead of diversity, the longstanding board criteria at Berkshire Hathaway (ticker BRK/A, BRK/B) include “business savvy,” “high integrity” and a “deep genuine interest in Berkshire.”
