Management
So I would say – thank you for the question, Melissa. So I would say all of the above because I think all of the solutions that we bring to market, we're bringing them because we had absolutely discussed with our customers before. There's some which, of course, have more urgencies depending on the customers. On the financial market, it'd definitely be the File Integrity Monitoring which is absolutely – everybody's really waiting for us to reduce that GA. We have a big pent-up demand, and this is because the financial institution File Integrity Monitoring is a regulatory aspect to that and the current solution that they use are very expensive to use and to deploy. Not that they are bad solution. In fact, they are pretty good solution, but they require servers that are huge infrastructure because they have a lot of data. So the cost of maintaining, supporting, updating the solutions, these traditional enterprise solution, this is the Siebel system versus Salesforce.com playing here, phenomena. So that's for that. The detection of Indication of Compromise is much more broader, so a broad appeal for small, very large and old companies, very hot odd market. So we see today the huge pent-up demand for these. Of course, it's going to take some time to get that translating into revenues because you need to go through the budget approval, et cetera. And our customers have the tendency for most part to put the up sell at the anniversary date of the subscription. So we've got kind of a lag, but I can tell you one thing. Everybody – the betas that went down, everybody is absolutely very happy with that, and that's another reason to further consolidate application, consolidate a lot of these old enterprise security solution which, as we all know, are difficult to install, to maintain and to deploy. And so that is very good for us.
Melissa A. Gorham - Morgan Stanley & Co. LLC: Got it. That's helpful. And then just one quick one for Melissa on the margin performance this quarter. So the results were obviously better than what you guided to and you noted a few factors, but I'm wondering to what extent was the upside just driven by timing issues where there was maybe slower hiring than you initially anticipated or if this kind of reflects maybe a change in view in how you're balancing growth over leverage.
