RE:RE:If it is BRKAuto:
If it is BRK, I don't think they would be interested in a takeover. ENB is incredibly well run and BRK would just be treating ENB as an investment, just like APPL, or AMEX, or Coca Cola.
If it is BRK they would probably want BoD representation with the size of holding that has been accumulated (if this is not my imagination). At the outer edges, they might be able to provide some symbiosis through their Dominion acquisition.
If it is BRK, it should provide ENB shareholders with a great deal of comfort as it has been 5 years since BRK has found a whale.
BRK only buys heavily into the best of breed and they hold the position for years if not generations.
