Well, I'll tell you, we're keeping an open mind and an open line of communication, Fadi. There's a couple of positions, the CN's position obviously. We've always said we're willing to make reasonable agreements with reasonable folks, with reasonable arguments, that's not a reasonable argument. So I don't see any hope with that position to be able to come to any meeting of the minds. We'll just not to agree to disagree. We intend to grow that railroad, but certainly not going to divest that railroad. And we think at the end of the day, those facts matter. They matter to the customer. I think they'll matter to the regulator. But obviously, the regulator will have to rule on that. When it comes to the NS, we've got -- we will, assuming that the STB approves this deal, and we believe they will. We're going to inherit a commitment, a joint venture that NS and KCS entered into back in 2006, and we're going to honor that, but that was a commercial discussion. A commercial relationship was established. We're going to honor what the contract says, but using the merger application to try to gain something that you didn't commercially negotiate is not something that we're interested in considering. So again, we think that's a very reasonable position to take, and we're going to maintain that position. When it comes to UP and BNSF, obviously, some of their concerns happens to be around infrastructure. We believe that the infrastructure if used properly, in the Houston area specifically, is more than adequate for the level of business that we believe our synergies will bring. That said, should we exceed our synergies, should investment need to be made in cooperation and in partnership with BNSF and UP, there are mechanisms within those agreements now, those track rights agreements that allow for those investments to be had. So again, I think our position is reasonable, and I don't see that changing. When it comes to the other CSX, overall, I think we're making some progress with CSX. I believe we're in a very reasonable place, and we're continuing to have very progressive discussions.
