Is Berkshire Hathaway a Target for Activist Investors?

Charlie and I are probably a little affected by the experience we had in running one for a short period of time it's not been something we invested in significantly. We obviously made a major investment in Goldman Sachs and we continue to hold shares that came out of the warrants that we received when we made the investment in 2008 but I think I can't recall us making a investment banking purchase a marketable security involving an investment bank for a long timeCan you Charlie no I think generally we fear the genre more than we love it dear chairman.
