David Sokol, once a candidate to succeed Warren Buffett as the head of Berkshire Hathaway Inc., resigned after helping to negotiate the acquisition of a company whose shares he had purchased.

Lubrizol, an Ohio maker of engine lubricants, agreed this month to be purchased by Berkshire for about $9 billion.
