Okay, so Tom let me do it -- let me make it pretty simple, right? This is, if you were to just take a straight line model of the last six or eight quarters, you can project it fairly well from where we’re at and what you would realizes is that, we wake up each quarter and we’re going to spend something like $3.5 million to $4 million a quarter right? And that includes some of the non-GAAP items of options expenses, so it’s not even real cash. Of that about $1 million is R&D, $1 million is about -- is typically our manufacturing costs that get embedded into our manufacturing cost of sales and about 1.5 million is SG&A, remember we’re still a public company and then I’d left out about $0.5 million of rounding here and there. Our systems, we typically sell at somewhere in the 50% to 60% type margins and that’s an incremental margin from there. And so we believe we can make a good business out of that, it’s a good rule of thumb, we don’t have to charge the margins that some of the larger players do, because we have a much lower overhead and so our scalability is, you go through that math and some around 6 million to 7 million depended with the margin is that makes up at that time, for the quarter we’re at breakeven and then we’re making $0.50 on the $1 there after. As we scale, one of the great things about this business is that, you need to start with some level of infrastructure maybe that’s the bad thing. We’re going to spend that money, whether we ship anything or not. But then I can ship a significant amount of capacity. We put in place to supply chain, a word class supply chain to be able to address these new products with every sub-system, major sub-system has a second source. So that we can supply capacity well, well in excess of our current revenue levels. If you come to our facility, you can see our infrastructure here is similar to that which I had in my last company where we were doing literally $200 million to $300 million a year. I’m not projecting that, that’s not what I’m trying to put in forward statements here. But what’s important is if a customer comes along and needs to order a number of systems, you need to have the ability to be able to ship those both on short lead times and within diverse [ph] type capacity. So that’s a simple model for you. Again, one of the first questions from Christian was, how big can will be? We’re not projecting that out, but we certainly do anticipate that we will have significant growth this year and we’ll continue that in the following year.
