Investors need to understand that Team Buffett is generally a passive investor. That said, Weschler and Coombs have been encouraged to take board seats on companies they invested in. With those few exceptions, Berkshire Hathaway recently issued a press release signaling that the company wishes to avoid owning 10% or more of the outstanding shares of public companies. Yet, some companies are repurchasing and retiring their own shares and that can sometimes require Berkshire Hathaway to make minor sales to avoid hitting the 10% threshold.
