Sure, Bill. Let me start with the final part. Right now, 50% of the fleets we have in the U.S. are 24-hour capable, and by far, those are the fleets that work the most hours on any given week. So the utilization is the highest with the 24 hours. We expect to be, this time next year, far higher than we are today with 24-hour capability. As far as the initiatives that were underway, the big one being supply chain and all that it encompasses, particularly logistics and procurements and R&M, I'd say that we're probably second base, and the time to improvement in that particular space is a little bit lengthier than, let's say, some of the early wins we had in some of the other areas, like, for example, converting to 24-hour fleet. Efficiency gains with the fleet in other ways, making sure it's in the right markets, is, I think, essentially complete. Another component which you didn't mention but was a big driver for us year-on-year was the customer mix, Bill. And again, there, I'd say we're probably, again to stay with the baseball analogy, say, between second and third base. You can always do a better job of not only high-grading your mix, but working with the customer to make sure that they're being more efficient. So we've made good improvements there. I think if you look at our top 20 list, it reflects a big percentage of the U.S's leading clients in the space with regards to pad drilling and understanding the subsurface and having the rig count to keep our fleet active, so somewhere around second base. And in terms of margin progression, as I think I highlighted on a previous question, still a very, very large gap between the -- that particular product line, which is our largest in North America, and our other business lines. I think, as we said in our prepared remarks, record revenues for many of the other product lines and what we didn't say, but if you remember, whether it was chemicals or Artificial Lift or completions, we had records in those last quarter, so 2 quarters in a row with some of these product lines. So we still have a lot of opportunity, and I would expect that 4 will be better than 3 and 1 will be better than 4 and every quarter going forward, of course, with a Q2 normal hiccup in Canada. Hope that answers your question.
