Is this an actual offer? Its one thing to theorize about it, its quite another to have $500 million actually waved in your face. I would need a direct comparison to know for sure; $500 million on the one hand, my Johnson in the other.
On second thought, if I had $500 million, my Johnson would be a primary beneficiary of the things I could buy with $500 million. So...without one, there would be no point in having the other.
