Okay. I would take this C.J. Growth on deferred revenue; first of all it’s in our mind a significant achievement that we know have this predictability of the installation because that takes one of the big hurdles to recognize revenue in the same way as EUV away. So we basically have two elements, we have the shipment and then we have certain performance criteria that we have to achieve later on. So in this particular case, it was a 3350 you know what the price of that tool is. It’s in the mid 90’s. So you can do the math what we’re going to recognize for that tool in 2017, I guess. The performance criteria is linked to the target that Peter mentioned in his remarks. So, as we are achieving these, you should expect us in the next year 2017 to also recognize that part closer to shipment. So also in Peter’s remark already we said that for the 2017 shipment, we’ll recognize the majority. And I have to tell you it’s a little bit different customer by customer, but it is the majority, as you have just seen from this 3350. We will be not only able to recognize the majority of revenue closer to the shipment, but we will also catch up from this year shipment. So we shipped units for instance in the first half of the year that will see no revenue in 2016, so you’ll see catch up there. So we’re very pleased with that. In the meantime while we’re looking, so the last couple of bumps there to get to the DUV like revenue recognition, we will update you on a quarterly basis on what the revenue will look like, just like we did for Q4, we have we have one system at sixty but then we have deferred revenue coming in at an additional 80 million. As it relates to the gross margin couple of points there. First of all, the objective is clear. By 2020, we want to be at 40% gross margin. If you pair that with our other businesses, DUV will somewhere in the 50% range and holistic lithography were north of 70% and then our CLS business that’s the Cymer service business which is also in the mid 50’s or so. You can see that that gets us to the 50%. On a standard cost basis, we are very close to where we want to be right now, you can impute that from the information we gave you that the one shipment that we recognized last quarter at a 1.4% dilutive effect. If you do the math, you’ll figure out it’s somewhere in the mid-teens percentage-wise and that’s not full revenues. So you can you see from a standard perspective, we’re doing, okay, but of course we’re shipping only a few systems this year. If you look at the total EUV business, isolated from one machine, you have to take several other considerations. Number one, we have the infrastructure to build many more systems. So we have - we have cost of under absorption. We have a service model where eventually we will charge per wafer the good wafer out. We provide the service already but there’s not many good wafers out. So you can imagine that that’s a very significant loss business for us right now. The learning curve, we are still looking on cost not only internally but also with our suppliers. And then there are other are areas like we still have to go out in the field and bring these systems that we shipped up to the later stand-up which is also of work that we need to perform that is unpaid. And lastly, we have of course shipped this year mainly shipped and will ship 3350s 3300s and then going starting next year, we have 3400s which come at a higher ASP. So you should take this all into consideration and you look at the overall EUV business, it is still significantly negative gross margin for us. But the standard is approaching where we needed to be and with the volume coming in, it really depends on volume and learning curve and we believe based on what we see in backlog and based on what we hear from our customers, I mean DSM for incidence was very explicit about their EUV plans going forward and Peter mentioned the ramp will be in 2018, 2019. We believe we can get to that 40% that gets the company to 50%. I hope that was not too much detail but you asked so.
