Okay. Thanks, Andrew. So let me take some time on this one. This is an important question. So first off it is fair for you to expect us to drive the sequential improvement in gross margin every quarter for the remainder of 2019, and let me explain the drivers. First, of course, is 5G growth that will drive improved scale, which will provide us with improved leverage, right? And there are two distinct parts to this. Number one, we expect 5G deployments to accelerate meaningfully in the second half and we have visibility to where those countries are where those contracts will be. Two, also as we highlighted, we delivered approximately €200 million of 5G hardware in Q1 that we were unable to recognize revenue on. And we expect that to be captured in full by the end of the year. So that's the first point, 5G growth. The second is product mix. And that will improve, one, because within Mobile Access, we expect a higher mix of software sales, following a Q1 during, which we did not have any software releases, not 4G, not 5G. 4G because of the compatibility with 5G and 5G because of what I've mentioned, revenue recognition. And two, if you move beyond Mobile Access for a minute, there are also several drivers of improvement. Number one, improved scale in Fixed Networks, which was down a lot in Q1; FP4 product cycle in IP Routing, structural cost benefit we have there; third, PSE-3 cycle in Optical that's coming later in the year. And then on the third big point in Services, which is within Mobile Access as I mentioned the particular challenges we are seeing are limited to a couple of services contracts where we had cost overruns and I'm confident that we can drive significant improvement in our execution in the remainder of the year. Plus we also expect cost reductions in Services, which is part of cost of sales and hence will improve gross margin. And more broadly speaking, we're focused on improving our overall product costs. Obviously we're in a new technology transition and as we progress through the 5G technology cycle, I can assure you that we've already taken the necessary actions such as more sharp chipsets, system on chip products et cetera to start in 2019 and later in 2020.
