^ I agree with Parsads logic here. It is common practice that pot. conflicts of interests are disclosed if you work for a company and that if such a conflict arises, somebody else or a committed would have to make decision on a transaction. I recall some cases, where a company takes over a company, where the CEO has a personal stake in and the board or a omitted needed to decide.
The deal looks proper to me, the disclosure was fair and the price of the transaction does not indicate any favorites, but it would be interesting how BRK internally deals with these conflicts of interests. It would be good to get some disclosure in thr SEC filings on that matter. This is particularly important because WEB will pass on the batton in a few years.
