. >> tom: daniel rohr is a metals and mining analyst from morningstar and joins us from chicago.dan, how unique of a deal is this in the u.s. to have mining and energy drilling all in the same company? >> it is very unusual, forthe p. decades, ago, however, we had seen a lot of the oil majors, folks like amco, with exposure to mining as well. this is an animal we haven't seen in quite sometime in the u.s. >> tom: what drove the deal for freport, why did it want to go outside its expertise mining, that was two generations of leaders ago. why now? >> yeah. i'm still struggling with the underlying strategic rationale for this deal. judging by the stock market, i can't see a clear rationale as far as why they did this. what management has said is they see a compelling story for oil and gas demand over the next several decades, and the purchase of plains and m.n.r., was a good way to bet on that outlook. >> tom: i suppose one point that is worth exploring here is little bit, mac moran and mines around the world, they're mostly based here in the u.s. is that a big change, and why that?
