Good morning, and thank you for joining us on today's conference call to discuss Palo Alto Networks fiscal third quarter 2018 financial results. This call is being broadcast live over the web and can be accessed on the Investors section of our website at investors.paloaltonetworks.com. With me on today's call are Mark McLaughlin, our Chairman and Chief Executive Officer; Kathy Bonanno, our Chief Financial Officer; Mark Anderson, our President; and Nikesh Arora, Palo Alto Networks newly appointed Chief Executive Officer. This morning, we issued a press release announcing our results for the fiscal third quarter ended April 30, 2018. If you would like a copy of the release, you can access it online on our website. We would like to remind you that during the course of this conference call, management will make forward-looking statements, including statements regarding our financial guidance and modeling points for the fiscal fourth quarter and full fiscal year 2018. Our competitive position and the demand and market opportunity for our products and subscriptions; benefits and timing of new products and subscription offerings; and trends in certain financial results, operating metrics, mixed shift and seasonality. These forward-looking statements involve a number of risks and uncertainties, some of which are beyond our control, which could cause actual results to differ materially from those anticipated by these statements. These forward-looking statements apply as of today, and you should not rely on them as representing our views in the future, and we undertake no obligation to update these statements after this call. For a more detailed description of factors that could cause actual results to differ, please refer to our quarterly report on Form 10-Q filed with the SEC on February 27, 2018, and our earnings release posted a few minutes ago on our website and filed with the SEC on Form 8-K. Also, please note that certain financial measures we use on this call are expressed on a non-GAAP basis and have been adjusted to exclude certain charges. For historical periods, we've provided reconciliations of these non-GAAP financial measures to GAAP financial measures in the supplemental financial information that can be found in the Investors section of our website located at investors.paloaltonetworks.com. We would also like to inform you that we will be participating in the Bank of America 2018 Global Technology Conference on Wednesday, June 6, in San Francisco; and the 2018 William Blair Growth Stock Conference on Wednesday, June 13, in Chicago. And finally, once we have completed our formal remarks, we will be posting them to our Investor Relations website under Quarterly Results. And with that, I will turn the call over to Mark.
