Let me just answer the first part. It's been a great acquisition by any measure for us. But if I go back, I look at our other large acquisition, DALSA, when we acquired it in 2011 it had relatively compressed margins. Now, e2v has good margins. But DALSA this year enjoyed margins approaching 20%. e2v on the other hand, while it has good margins, please recall that overall their margins are lower than DALSA and partially because we have intangible amortization. In the Digital Imaging for example, e2v's amortization for this year 2018 is about $11 million. So, that compresses the margin. And consequently, e2v's overall GAAP margins are lower than DALSA. Going forward, I think because of the intangible compression, e2v will grow the overall margin for Digital Imaging. Having said that, DALSA used to have a compressed margin, but its margins have more than doubled. The same thing with LeCroy. When we bought LeCroy, it had very low margins. It has more than doubled since our acquisition. And if we do what we did in those domains with e2v, I think our margins will improve with time. There also you asked a question of how some of those products may carryover to other segments. First, in the space imaging domain we have between DALSA, Teledyne Imaging here, and e2v, we practically own the visible and the infrared businesses for astronomy and we are making some large in-roads in defense programs. Similar to e2v, because e2v has not had access to the U.S. defense market, we expect that we'll be able to introduce some other product into our defense markets here, which is of course a bridge across to our other products. Also, we have inherited some really outstanding high-performance analog-to-digital and digital-to-analog conversion devices that cut across all of our businesses. Between what they bring and what we have, I think we'd have a significant overlap, and certainly hope in all of our other segments. So, it's been a great acquisition. It doesn't have the margins that DALSA has. But DALSA didn't have the margins it has now and when we acquired it, but it does have highly margin. We've got mid double-digit margins even with amortization of intangibles that I mentioned.
