All right. Got it. And now, David, perhaps you can give us an example of one these VBUs, just how many people are in it, what do they do, what's your configuration.
David Reis - Chief Executive Officer & Director: Sure. It's a very good question. I think a few years back, we realized that there is a requirement from the market for us to become specialized in the different industries that we operate in. And I think it's clear to you and to, I'm sure, the rest of the people on the phone that there are substantial differences, for example, between the medical space and the aerospace business. So what we did, we – the initial steps were done in Stratasys before the merger. It was a very small team. They – past the merger, we spent and invested a lot of money and thoughts on building a group that its goal is to develop our capabilities into different verticals that we believe are the leading verticals in our industry. And we're talking about auto, aerospace, medical, dental, jewelry, and education as a subset of them. And this group is consist of quite a bit of employees and managers. And their task is to become specialists in respect to those markets, develop with customers specialized application, and later on, impact R&D to develop solutions which are tailored for those applications. Now, this team, when they conclude the work of developing certain application or a certain solution, they create the necessary tool in order for our core sales and marketing infrastructure to adopt this new development and sell it to the wider market. So it's kind of like maybe kind of a special unit, special forces which are running in front of the company with customers, developing specialized application mainly in tooling and manufacturing, and later on bringing them to the wide Stratasys core sales and marketing infrastructure to be able to sell it to the wider audience.
