Well, two-course [ph], I don’t think customers are really lagging, one. But they have different areas of focus, and they have different road maps and timing of road maps which they would like to execute and also the size at which you want to do is also different. So this is not an homogeneous pack, this is heterogeneous three different customers, three different road maps, three different ways in which you want to execute this. But I think you’re actually correct, when you refer to the public statements which are very convincing. It’s only the public statements as you can imagine, we are in very close contact with them, and we are also seeing what they’re doing in preparation of that EUV. And that’s real tangible, I mean that those are factories, those are EUV better stores, those are that’s EUV infrastructure is being built and being put into place into those fabs. So that is also tangible, which is not that visible, but to us it is. On the negotiation process that’s also different per customer. For instance one of those customers doesn’t have a volume purchase agreement yet, but they have orders in our backlog. So they have order tools without of EPA. But the volume purchase agreement is ready to determine in their best interest. What their pricing is on a certain volume there is a commercial negotiation, which - as many asking the previous question is also a matter of how many options do you want or what do you want to pay for those options. So these things are commercial negotiations, which are not fully detached from the planning of what they want to do, but it is a different process, so you have the planning process for the production, which we’re pretty close to, which actually drives our own planning, our own production planning and you have the commercial process. That commercial process ends where it ends and this is where we are. So I think in summary, three different customers, not homogeneous in the way to look at the road maps, the timing of the road maps, not homogeneous in the way they negotiate. And not homogeneous also in the speed at which they want to do something and the speed of their ramp. So this is what we have to take into consideration, but again it’s try to put some color on what we said before is that we see this ramp up, we would be very clearly coming on the 7 nanometer, which means 12 units this year, which is now say around 20 units next year. And we could see a further doubling in the years thereafter when we look at the customer roadmaps and their execution planning. And I think that is the most important to mention, right now.
