Listen, probably best way to look at oil and gas is to go back to the compare and the prior year, and think about it from that perspective. Because that was a time of great uncertainty, remember oil, this time last year, went into the 20s and market see that. So, when the third and fourth quarters of '15 people were really holding on tight. By this period a year later, they're still very tight, they're still deferring things. But as we talked about, at least, we saw some emergency, repair work and activity occurring. That contributed also our broader footprint as we brought some of that online, we were able to participate in some more markets as well. So why we like the increase, especially considering the fact that that market has been challenged for a while, I think it had more to do with the lack of visibility in 2015 as a compare. Which is why -- and our comments right now we’re saying, the fact is we're three years into a cycle. This has been brutal, brutal cycle, particularly in the oil and gas industry. The fact is these things come back. So two things happen; one, as time passes, you get closer to the end of the downturn in the cycle that’s just the way the math works; the second thing is some of the things we've seen in some of the distributors, some of the other activities, and some of the fieldwork and everything, indicate that there is a little more comfort. As we anticipated now that oil is stabilized for, we're almost into the fourth quarter of stabilized oil. So, I think it's more of the compare in '15. There are some strategies that we've executed on that have allowed us to grow those bookings really in all those segments. But if you look at the segments that grew, it had more to do with '15 uncertainty than anything else. Keeping in mind in '15 and we talked about this, we had a couple of big projects like in our valve business and pulp and paper, some things that you don't see certainly on a recurring basis.
