I saw Todd interviewed by Seth Klarman at the Boston Invest Conf in November. He did a fantastic job and had some interesting things to say about what its been like working with Warren and especially Charlie. ( all positive)

Like most of you, I have followed his career since the day he and Ted were announced as the guys put in place to take the mantle from Warren on capital allocation. My guess is that he left for the same reason Lou Simpson did after that announcement....Some of you might recall that the official word was that Lou was retiring. He proceeded to start managing individual accounts with his wife as the ops manager of the new company right away. He clearly felt disrespected and passed over after years of loyal service because of his age. ( Warren said that Lou wasn't that much younger than him as Lou was in his 70's)

Not everyone wants to stay at BRK forever. Tracy Britt had a position similar to one of those announced today and left her "dream job" to start her own fund.
