That's $6.5B at todays prices, throw in a few more price changes and it will be closer to $20B by the time the five years is up. Not bad for a 20c stock, I'm thinking about renaming my first born Brockman :-).
As with most long termers here, I'll be keeping hold of mine with still so much upside the story keeps getting better.
I note this is not yet formally announced, only newspapers currently?
