Well, I don't know much what I could add to the comments that you just heard from Alan and Raj. Basically, the perspective of Wall Street is always give me the money; perspective from inside FedEx is what's the best thing we can do for the long term. Now, there have been some exogenous factors that have happened. First, let me remind you that in June, June 27th of 2016, FedEx was in the middle of the largest state sponsored cyber attack in history, so-called NotPetya account that brought the British health care system almost to a halt, cost hundreds of millions of dollars for Maersk, the big sea container line. I think, I'm right, it cost $1 billion dollars to Merck, great medical company. So, had TNT been a standalone company at that time, it would have been bankrupt. We did [indiscernible] Rob Carter and his people in recovering from that. So, I would say that the slowdown in the TNT situation on the Express side because of NotPetya was substantial as we reported at the time. Second issue, but as Raj told you, we are very optimistic about our intercontinental network and the ability to improve margins in the Express business, because of the integration. On the Ground side, the issue is very straightforward and that is the market changed from more business-to-business to business-to-consumer. So, we could basically have decided not to address that. But as Brie mentioned and Raj both, we decided that we wanted to play in that space and that we were not only playing in it, we were going to be the market leader, and we’ve gained market share in that sector for 18 consecutive years. So, I think we've got a pretty good track record of that. So, we started this fiscal year, very optimistic about our ability to expand margins and to hit on all cylinders. But as I tried to lay out in my remarks, we anticipated a $6 billion revenue increase. We're going to end up with about $4.5 billion. And this is a leverage business and to the extent that the last few percentage of revenue points go to the bottom line at a very disproportionate rate. So, that hopefully answers your question, I mean, we're not unmindful to the issues that you're talking about, but we do think we've got a good runway in the future because we've made those investments.
