Let me take the frontend of that Jason. There's no question that the products that Merit is developing are more difficult to produce. They take more time, but they have more value both to the clinician and to the Company. It's full and I've used it for lot, but it still holds true it just sticks to stitch, but it doesn't mean that the stick is cheap either. And everything in between is moving up the food chain in terms of its complexity, but the value that it brings that position. And consequently, we get a higher price marginal and the ideal is -- I think the prime example of that. If you look at sheath, you might be talking about maybe a $10 range, but with these particular sheaths because of their unique capabilities and specifications, you could be talking about $55, $65 $70. So it’s that kind of movement in products, as you also know the Company is complex with lots of products and its one of the hard things, so I think analyst is so many pieces to all of this. But that being said we continue to add products that our customers need, where we see opportunities broadly. And so it always takes a little bit more time to get these things overseas, but let’s take an example of China it could take two or three years before the products that were talking about today are going to be there and approve, but that being said, I think that speaks volumes to the sustainability of margin improvement and growth. So it's something we've done for long time, we have infrastructure in place and many of these locations were reviewed distribution in the past, we now have a direct or modify direct systems there. So whether it be logistics whether it be the face-to-face with customers and closer to the point of sale, the pipeline itself and let’s not forget things like Rhapsody, which is going to be first in man in August. Now this is a product that we talked a little bit about, you will start to hear more about this. This is a fully covered central venous stent. So as we start to move down the road, you’re going to see continued therapeutic types of devices that have substantially better margins. But that's a Merit, when Merit walks into lab, we’re there to help every aspect of that procedure, and I think that's what makes Merit really unique, things with other people ignore we don't. We think there's a huge opportunity for service to our customers and to our shareholders. So, I couldn’t be more pleased with where we are the Company date, maybe more importantly where were heading.
