Yeah, sure. I mean, I would say, first of all, I mean, we do guide on cash costs, and we do try to take everything that's happening in the year into account when we're doing that. As you point out, we're actually challenging the lower end of the re-guided numbers. The most important part of getting the cash costs down is reliability. And we have seen – becoming, again, increasingly confident in the levels of reliability we're seeing for the plant. If you look, last quarter disappointed us, but if you looked at the last eight quarters, you'd see that we've been doing very well consistently through that piece. We haven't finished in terms – so reliability, we're continuing to work on it, you've seen what Firebag has done as it's come back from its turnaround. These five-year runs are working, and then the plants are coming back in a very reliable condition, which is very encouraging to us. We're continuing to work on what I will call the nuts and bolts of our business. So, as the reliability comes up, we can start to look at where we put our priorities, where we put our manpower. And we've been able to reduce costs through that piece steadily. It gets tougher as you go on. I mean, you clearly go in and get the low-hanging fruit first and then you move on to the more difficult issues. But we still have lots of things we're working on. So, generally, you will see that trend continue. If you look at things like mining, you know we've been working on a program of automation there, which – and I'll use this one by way of example, automation which lowers maintenance costs, increases the productivity of the vehicles, increases the production of the mine. So that has gone very well. It's commercially successful. So, you'll see us continue to work on initiatives like that where we steadily get reliability up and reduce real costs. I mean, Alister pointed out that we've actually, with all the capacity increases we've had since 2014, 25%-plus, we have actually reduced the absolute costs, even accounting for that 25% increase in production. So it's been significant. You're going to see more of that. As we finish these big investments, we also get the opportunity to refocus again. So these are – a project the size of Fort Hills takes a considerable amount of attention. Some of that attention is going to come back into our base operation as we consolidate our base operation again and integrate those operations into the business. So, yeah, I'm confident you will see a slow but steady trend on costs down and reliability up.
